Expressing Opinions

I think, I believe, and In my opinion express your opinion or degree of confidence. You can follow them with a complete sentence. A common soft negative pattern is I don't think + an affirmative sentence.

Expressing Your Opinion

1. A frame before an opinion

I think helps you present an evaluation or uncertain information in your own voice. I think the bridge is beautiful — an evaluation; I think the shop closes at nine — an assumption about a fact that can be checked.

A useful opening pattern is: put I think, I believe, or In my opinion at the beginning, followed by a complete sentence with its own subject and verb. These phrases can also appear in other positions, but here we are practising this one.

How to build it

I think / I believe / In my opinion + complete sentence

I think the new bridge is beautiful.

I think the new bridge is beautiful.

Beautiful is an evaluation, so the frame I think is useful.

In my opinion, the weather is too hot today.

In my opinion, it is too hot today.

The phrase In my opinion opens the sentence and is separated by a comma.

I believe that this neighbourhood is safe.

I believe that this neighbourhood is safe.

A separate sentence, this neighbourhood is safe, follows the frame.

2. I think and I believe

The frames I think and I believe have the structure subject + verb. You can put that after them, or leave it out: the meaning is the same. In conversation, people more often speak without that.

I think is common in everyday conversation. I believe may sound more formal or emphasise conviction; the strength of the confidence also depends on context and intonation.

How to build it

I think (that) + sentence; I believe (that) + sentence

I think that our teacher is very kind.

I think that our teacher is very kind.

You can leave out that: I think our teacher is very kind.

I believe our plan is realistic.

I believe that our plan is realistic.

I believe shows conviction. Is comes after the subject our plan.

3. In my opinion

The phrase In my opinion always uses the preposition in. The alternatives on my opinion, at my opinion, and by my opinion are common mistakes.

At the beginning, In my opinion is usually separated by a comma. It is a familiar phrase for expressing your own evaluation. According to usually refers to a source of information, so choose In my opinion for a simple personal opinion.

How to build it

In my opinion, + sentence

In my opinion, the first lesson was the best.

In my opinion, the first lesson was the best.

After the comma comes a regular sentence with the subject the first lesson.

In my opinion, this dress is too bright.

In my opinion, this dress is too bright.

Too bright is an evaluation, and the frame introduces it.

4. After the frame — a complete sentence

The frame only introduces the opinion. The sentence that follows it is built like a regular affirmative sentence: subject, then verb (often is or are), then the rest. The word order does not change as it does in a question.

In the pattern think + complete sentence, be is needed before an adjective: I think this idea is good. There is also the formal construction think + object + adjective, but here we are practising the simpler pattern with a complete sentence.

How to build it

frame + subject + verb + the rest

subject / S
—
The grammatical subject: who or what the clause is about; the verb agrees with it. In The book was written, the book is the subject, although someone else does the action.
verb / V
—
A word for an action or state, such as work or be. The pattern determines its form.

I think the neighbours are friendly.

I think the neighbours are friendly.

The subject the neighbours is plural, so use are.

I believe that the trains are late today.

I believe that the trains are late today.

After that comes a separate sentence with the subject the trains.

5. Negation: I don't think

To say “I don't think that…”, put the negation in the frame: I don't think. The sentence after it remains affirmative: I don't think the restaurant is cheap. You can also say I think the restaurant isn't cheap, but in this rule we are learning the form I don't think: the negation is in the frame.

This sounds softer than a direct negative statement. A double negative (I don't think … isn't) changes the meaning, so avoid it.

How to build it

I don't think + affirmative sentence

I don't think the restaurant is cheap.

I don't think the restaurant is cheap.

Don't comes next to think, while is cheap remains affirmative.

I don't think these shoes are comfortable.

I don't think these shoes are comfortable.

The subject these shoes is plural, so use are.

6. Think about and think + sentence

Think about + a noun means “consider or reflect on something”: I think about my holiday. There is no evaluation here; there is only the subject of the thought.

Compare “I think about my holiday” and “I think my holiday was wonderful.” For the second meaning, say I think (that) my holiday was wonderful, without about before this sentence.

How to build it

think about + noun ≠ think + sentence

noun
—
A word naming a person, thing or idea: student, book, happiness.

I think about my holiday.

I think about my holiday.

The noun my holiday follows about; there is no evaluative opinion.

I think my holiday was wonderful.

I think my holiday was wonderful.

A complete sentence with the evaluation wonderful follows think.

7. Opinion, reason, and softening

The frame shows your position. To explain it, you can add a reason with because or use a separate sentence.

The frame is not necessary every time: you can state a fact without it (The shop closes at nine). But for evaluations such as good, boring, and expensive, the frame makes the language more polite.

How to build it

frame + opinion + because + reason

I think this dress is nice because the colour is bright.

I think this dress is nice because the colour is bright.

Because answers the question “why?” and introduces a new sentence.

In my opinion, the dessert is sweet. I like it.

In my opinion, the dessert is sweet. I like it.

You can give the reason or explanation in a separate short sentence.

8. Limits of the rule

Here we are learning how to express your own opinion. Questions such as What do you think? and answers such as “I agree / I disagree” belong to related rules in this topic.

I think can be used both with evaluations and with assumptions about facts that can be checked. The frame does not change whether the statement is true; it shows how the speaker presents it.

How to build it

here: express your opinion; not here: ask for an opinion or agree

I think the shop is too small.

I think the shop is too small.

This is a personal opinion, not a question or an expression of agreement.

What do you think of the shop?

What do you think of the shop?

This is a question about someone’s opinion; it is taught separately.

Common mistakes

Incorrect:On my opinion, this soup is salty.

Correct:In my opinion, this soup is salty.

The English phrase uses the preposition in; on, at, and by do not work here.

Incorrect:I think this soup are salty.

Correct:I think this soup is salty.

Soup is singular here, so the complete sentence needs is.

Incorrect:I think about the weather is cold.

Correct:I think the weather is cold.

Before the complete statement the weather is cold, this pattern needs think (that), without about.

Incorrect:In my opinion, the test be easy.

Correct:In my opinion, the test is easy.

In an ordinary statement in the Present Simple, the test needs the form is.

Incorrect:I am think this movie is good.

Correct:I think this movie is good.

In the Present Simple, do not add am before think. For an ordinary evaluation, I think is enough.

How to agree or disagree

Agreement: three ways to say yes

When someone gives an opinion, you can support it. Simple responses are I agree (with you), That’s true and You’re right. Each expresses that you see the matter similarly.

I agree is the most direct of these. That’s true and You’re right affirm that the statement is true. Adding a reason after any of them helps the agreement sound engaged rather than mechanical.

Other common expressions include That’s right, Exactly and I totally agree. If the other person makes a strong argument, you can say That’s a good point: point means an argument here, rather than a punctuation mark.

How to build it

I agree (with you) / That’s true / You’re right → agreement

I agree with you about the new schedule.

I agree with you about the new schedule.

Agree takes with before a person.

That's true. Trains are faster than buses here.

That's true. Trains are faster than buses here.

The second sentence adds a reason.

You're right. The shop closes at nine on Sundays.

You're right. The shop closes at nine on Sundays.

Be + right means having the correct view.

Disagreement: direct or softer

Disagreement can take different forms. I don’t agree clearly states that you have another opinion. I don’t think so is a short response to an opinion or question. I’m not sure about that expresses doubt and is the softest of these options.

You can add a reason to make your position easier to understand. It helps the conversation, but neither guarantees agreement nor forms a compulsory part of the reply.

I’m not so sure (about that) also expresses doubt. I totally disagree emphasises strong disagreement, while Absolutely not is a firm rejection. Strength and politeness depend on context and intonation; I’m not sure about that is a useful opening for softer disagreement.

How to build it

I don’t agree / I don’t think so / I’m not sure about that → disagreement

I don't agree. The test was fair.

I don't agree. The test was fair.

Direct disagreement with a reason.

A: It's too hot to walk. B: I don't think so. It's only twenty degrees.

A: It's too hot to walk. B: I don't think so. It's only twenty degrees.

A short response followed by a reason.

I'm not sure about that. The museum may be closed today.

I'm not sure about that. The museum may be closed today.

Doubt sounds softer than direct disagreement.

The verb agree: no be, and with for a shared opinion

Agree is itself a verb: I agree, you agree, she agrees. Do not transfer an adjective pattern from another language into I am agree; no auxiliary be is needed before agree here.

Form negatives with do: I don’t agree, she doesn’t agree. I’m not agree is incorrect. To name the person or opinion, use agree with: I agree with Kate, I agree with her idea.

Agree to occurs with a different meaning: accepting a proposal or condition. This lesson concerns sharing an opinion, so with is needed.

How to build it

I agree with + person / opinion; I don’t agree with + person / opinion

She agrees with her brother about the music.

She agrees with her brother about the music.

Add -s after she, but no be.

We don't agree with the new rules.

We don't agree with the new rules.

Don’t forms the negative.

I agree with Nina's idea.

I agree with Nina's idea.

With also precedes an opinion.

Polite disagreement: acknowledge first, then use but

Saying no directly can sometimes sound too abrupt. First acknowledge the other person’s point, then return to your own: I see your point, but... or That’s true, but....

The response has two steps: a concession and a contrasting response. But marks the turn; a reason or your opinion usually follows it.

I see what you mean, but... works similarly to I see your point, but....

A reason can make the response more persuasive. I see what you mean, but I don’t agree is polite but gives little explanation, so adding why is helpful.

How to build it

I see your point, but ... / That’s true, but ... → acknowledgment + another view

I see your point, but the train is cheaper.

I see your point, but the train is cheaper.

Acknowledgment, then but and an argument.

That's true, but I prefer small shops.

That's true, but I prefer small shops.

That’s true acknowledges part of the point here, rather than expressing complete agreement.

Choosing your response

Before replying, ask whether you fully agree, partly agree, have doubts or disagree. Full agreement: I agree, That’s true, You’re right. Partial agreement: I see your point, but.... Doubt: I’m not sure about that. Direct disagreement: I don’t agree, I don’t think so.

You’re wrong is grammatical but can sound abrupt. For softer disagreement, choose I don’t agree or I’m not sure about that and add a reason if useful.

Tone also depends on the situation: a friend may need only a short reply, while a business chat often benefits from a reason and respectful wording.

I'm not sure about that. The shop may be closed on Mondays.

I'm not sure about that. The shop may be closed on Mondays.

Soft doubt with a reason.

I don't agree. The price is fair for the quality.

I don't agree. The price is fair for the quality.

Direct but polite disagreement.

You're right, but I still prefer the old plan.

You're right, but I still prefer the old plan.

Agreement with part of the point, followed by a personal preference.

The lesson’s scope: responding rather than starting a conversation

This lesson concerns responses to someone else’s opinion. Expressing your own view with I think or In my opinion, and asking What do you think?, are separate topics.

A response can also include I think, for example after but. The main purpose is then to show your reaction to what was said: support, doubt or disagreement.

A: Dogs are better pets than cats. B: I'm not sure about that. Cats are quieter.

A: Dogs are better pets than cats. B: I'm not sure about that. Cats are quieter.

A response to A’s opinion rather than a conversation opener.

A: The new park is lovely. B: That's true, but I think it's too small.

A: The new park is lovely. B: That's true, but I think it's too small.

I think belongs to the second step; the main response pattern is That’s true, but.

Common mistakes

Incorrect:I am agree with your idea.

Correct:I agree with your idea.

Agree is already a verb, so it needs no be, even if a first-language adjective pattern suggests it.

Incorrect:Mark has right about the date.

Correct:Mark is right about the date.

The expression for having the correct view is be right, not have right.

Incorrect:She is not agree with us.

Correct:She doesn't agree with us.

Negate agree with do/does + not, rather than be + not.

Incorrect:I agree to my sister about the film.

Correct:I agree with my sister about the film.

When sharing a person’s opinion, use with after agree.

Incorrect:I think no. It's too late.

Correct:I don't think so. It's too late.

The short disagreement pattern is don’t think so, not I think no.

Asking for opinions: What do you think…? / Do you agree?

1. Three ways to ask for an opinion

English offers three useful patterns. What do you think about…? asks for an opinion on a topic. What’s your opinion on…? does the same in a slightly more formal way. Do you agree (with…)? checks whether someone agrees with something.

These patterns invite someone to state a position: assess an idea, explain a view or confirm agreement. The answer can include both an assessment and supporting facts.

How to build it

What do you think about …? / What’s your opinion on …? / Do you agree (with …)?

What do you think about the concert on Saturday?

What do you think about the concert on Saturday?

An open question: the other person gives their assessment of the concert.

What's your opinion on the new library hours?

What's your opinion on the new library hours?

The same request for a view, with the noun opinion; it sounds slightly more formal.

Do you agree with Olga?

Do you agree with Olga?

A yes/no question about agreement: yes or no can be sufficient.

2. What do you think (about / of) …?

This is a very common pattern. After what, put auxiliary do, then subject you and verb think: What do you think? Add the topic after about or of: What do you think about the plan? / What do you think of the plan?

Leave out the topic when everyone knows what you mean: What do you think? People often ask this immediately after giving their own view or showing someone something.

Keep do before you in the question: What do you think, rather than What you think.

How to build it

What + do + you + think + (about / of + topic)?

What do you think about my presentation?

What do you think about my presentation?

Do comes between what and you; the topic follows about.

What do you think of the new bakery?

What do you think of the new bakery?

Of is just as natural as about here.

I've shown you the photos. What do you think?

I've shown you the photos. What do you think?

The topic is omitted because both people know what the question refers to.

3. What’s your opinion on …?

Opinion means a person’s view. This question consists of what’s (what is), possessive your, noun opinion and a preposition introducing the topic: on, of or about. There is no verb think, so auxiliary do is not needed.

Similar requests include What’s your view on…? and Do you have an opinion about…? These can sound slightly more formal than What do you think…? and suit workplace discussions or conversations with a manager.

Notice where is goes: before your opinion in the direct question, as in What’s your opinion…, rather than What your opinion is.

How to build it

What’s + your + opinion + (on / of / about) + topic?

What's your opinion on the new dress code?

What's your opinion on the new dress code?

Opinion + on: a neutral, slightly formal request for a view.

What's your view on remote work?

What's your view on remote work?

View is a synonym of opinion, often used in workplace discussions.

Do you have an opinion about the new timetable?

Do you have an opinion about the new timetable?

A yes/no question about whether someone has an opinion; a yes usually leads to an explanation.

4. Do you agree …? and Do you think …?

Do you agree? checks agreement with what has just been said. Add a person with with (Do you agree with Olga?) or a statement with that (Do you agree that the exam was hard?).

Agree is a verb in its own right, so form this question with do. Are you agree…? is not the correct pattern.

Do you think (that)…? checks whether someone holds a particular view. The following clause uses statement order, with the subject before the verb: Do you think the bus is full?

How to build it

Do you agree (with + person / that + clause)? / Do you think (that) + clause?

clause
—
A construction with a verb, often with its own subject: when I arrived. A non-finite clause may leave the subject unspoken: to get home.

Do you agree with the new lunch rules?

Do you agree with the new lunch rules?

Agree + with introduces what the person agrees with.

Do you agree that the show was too loud?

Do you agree that the show was too loud?

Agree + that is followed by a clause with the subject before the verb.

Do you think we need a bigger table?

Do you think we need a bigger table?

After Do you think, subject we precedes verb need.

5. Asking for an opinion rather than a method

A Ukrainian expression for asking someone’s opinion can be misleading if translated word for word as How do you think…? English how asks about a way or method. To request an assessment, use What do you think…? or a yes/no question with Do you think…?

Distinguish Do you think about the plan? from What do you think about the plan? The first asks whether someone considers the plan; a yes/no answer need not assess it. The second requests an assessment: “It’s good”, “It’s too long” or “I like it”.

Both questions are grammatical. Choose according to your purpose: asking for an assessment, or asking whether someone thinks about a topic at all.

What do you think about my new haircut?

What do you think about my new haircut?

What requests an assessment of the haircut.

Do you think about moving to another city?

Do you think about moving to another city?

This asks whether the person considers moving, rather than asking them to assess the move.

How do you think she will finish so fast?

How do you think she will finish so fast?

How asks what method the person thinks she will use to finish so quickly. This differs from requesting an assessment.

6. Open or yes/no questions, and inviting an answer

An open question (What do you think…?, What’s your opinion…?) invites someone to explain their view in their own words. A yes/no question (Do you agree…?, Do you think…?) checks a position quickly. Choose an open question for an explanation or a yes/no question to check agreement; either can lead to discussion.

To invite a particular person, use their name: Dan, what do you think about the plan? For a more formal tone, try Could I ask for your opinion on…? Ordinary What do you think…? also suits many workplace conversations.

After giving your own view, invite someone else in: I like the red one. What about you? or What do you think? A neutral question leaves more room for an answer: Do you think the rule is fair? is less leading than Don’t you think the rule is unfair?

Maya, what do you think about the new logo?

Maya, what do you think about the new logo?

The initial name directs the question to Maya.

Could I ask for your opinion on the budget?

Could I ask for your opinion on the budget?

A polite, formal option for addressing a manager.

I prefer the longer route. What about you?

I prefer the longer route. What about you?

After expressing your preference, invite the other person to give theirs.

Combining your opinion with a question

Briefly give your own view, then invite someone to speak: I think the route is too long. What do you think?

After someone answers, ask for their reason with Why do you think so?

What do you think about the new route? I think it's too long.

What do you think about the new route? I think it's too long.

The first sentence requests the other person’s opinion; the second expresses the speaker’s view.

Common mistakes

Incorrect:How do you think about my idea?

Correct:What do you think about my idea?

How asks about a way or method. To request an assessment of this idea, use what rather than translating the Ukrainian expression literally.

Incorrect:Are you agree with Olga?

Correct:Do you agree with Olga?

Agree is a verb, so this question uses do without be.

Incorrect:What you think about the concert?

Correct:What do you think about the concert?

This direct question with what needs auxiliary do before the subject.

Incorrect:What your opinion is on the schedule?

Correct:What's your opinion on the schedule?

In the direct question, is precedes your opinion rather than following it.

Incorrect:What's your opinion in the new menu?

Correct:What's your opinion on the new menu?

Use on, of or about to introduce a topic after opinion, rather than in.

Incorrect:Do you think is the shop open?

Correct:Do you think the shop is open?

After Do you think, use statement order: subject the shop precedes verb is.
