Why we learn these forms separately
Many adjectives use -er or more, but good, bad, and far have special comparative forms. It is easier to remember them in pairs: good — better, bad — worse, far — farther/further.
Better is also the comparative form of well (“well”, “healthy”), while worse is the comparative form of badly (“badly”). Therefore, in works better and feels better, the same form can have a different role.
This soup is better than the one I had yesterday.
This soup is better than the one I had yesterday.
good → better; the spelling of this form is not related to the word good.
The traffic today is worse than usual.
The traffic today is worse than usual.
bad → worse; it also has a separate root.
Three pairs to memorize
In this lesson, we focus on three pairs: good → better, bad → worse, far → farther/further. This is not a complete list of all the special features of comparison in English.
The form comes after the linking verb (be) or another verb of state (feel, look, sound, taste, get), just like a regular comparative: subject + verb + better/worse/farther/further + (than + the second participant).
X + be/feel/look/sound/get + better/worse/farther/further + (than + Y)
My back feels worse this morning.
My back feels worse this morning.
bad → worse; the comparison appears without an explicit than—the reference point (yesterday/earlier) is clear from the context.
The nearest hospital is further than I expected.
The nearest hospital is further than I expected.
far → further; the comparison is with an expectation, not with another specific object.
Her cooking has got a lot better since she started taking lessons.
Her cooking has got a lot better since she started taking lessons.
good → better; get better describes a change over time.
Why not -er or more
For an ordinary comparison of quality, use better and worse: This phone is better; the weather is worse. Do not form these words mechanically as gooder or badder.
More good or more bad are possible in other constructions, for example more good than bad—“more good than evil.” This is a different pattern, not an ordinary comparison of two things by quality.
For distance, use farther or further, not farer.
Better and worse already express the comparative degree. In a neutral standard comparison, more better and more worse are unnecessary; for emphasis, say much better or much worse.
This hotel is better than the last one, not more better.
This hotel is better than the last one, not “more better”.
better already expresses the comparative degree; there is no need to add more.
The line moved faster today, but it was still worse than I hoped.
The line moved faster today, but it was still worse than I hoped.
In this ordinary comparison with an expectation, we use worse.
Farther or further
Both words are comparative forms of far, and they are interchangeable for physical distance: The office is further from the station and The office is farther from the station are equally correct.
Further is also used to mean “additional”: further information—additional information. Farther is not used in this meaning. Could you explain this further? means “Could you explain this in more detail?”.
Practical tip: for physical distance, both forms are possible. For the meaning “additional”, use further: further information. There is no need to impose a broader ban on all figurative uses of farther.
The office is further from the station than I thought.
The office is further from the station than I thought.
physical distance—both further and farther are natural here.
We need further details before we can confirm the booking.
We need further details before we can confirm the booking.
the meaning “additional”—only further works here, not farther.
Comparison without an explicit than
Better, worse, farther, and further can appear without than when it is clear to the listener what the comparison is with.
I feel better—“I feel better”—often compares the present state with an earlier one. It is not necessary to say exactly what it is better than.
How are you? — Better, thanks.
How are you? — Better, thanks.
The comparison with the previous state is clear from the situation.
The forecast looks worse for tomorrow.
The forecast looks worse for tomorrow.
The context should make it clear whether tomorrow’s forecast is being compared with today’s forecast or with an earlier forecast for tomorrow.
In a sentence: negatives, questions, and short answers
The comparative forms themselves do not change in questions or negative sentences. With be: Is it better? / It isn’t better. With feel in the Present Simple, do/does is needed: Does it feel better? / It doesn’t feel better.
A short answer repeats only the auxiliary verb, without repeating better/worse/farther/further: Is it worse today? — Yes, it is. / No, it isn't.
Is/Was + X + better/worse + (than Y)? — Yes, it is. / No, it isn't.
This translation isn't worse than the last one.
This translation isn't worse than the last one.
the negative is formed with isn't; worse does not change.
Is the traffic better on Sundays?
Is the traffic better on Sundays?
the question is formed through inversion with is; better stays in place.
Common traps: when automatic habits let you down
The ending -er and the word more are regular patterns for other adjectives: heavy → heavier, expensive → more expensive. Do not transfer them automatically to good, bad, or far.
Compare: This bag is heavier than that one (regular, -er, the word heavy) and This bag is better than that one (irregular, a separate word, good)—both sentences are correct, but they describe different qualities using different mechanisms.
This bag is heavier than that one, but it's better made.
This bag is heavier than that one, but it's better made.
Heavier is formed from heavy; better made means “made better” and has the adverbial meaning of well.
The new laptop is more expensive but works better than the old one.
The new laptop is more expensive but works better than the old one.
More expensive describes the laptop, while works better describes how it works; better here is the comparative form of well.
Using them in speech
These forms help you talk about how you feel, quality, weather, distance, and change. Choose the one that accurately expresses the quality you need.
The aim of this material is not only to recognize a form in someone else’s sentence, but also to use it freely by creating your own advice, complaints, praise, and accounts of real or imagined changes.
I think this plan is better than the one we discussed last week.
I think this plan is better than the one we discussed last week.
a personal evaluation in a work context.
My flight leaves from a terminal that's further from the entrance.
My flight leaves from a terminal that's further from the entrance.
a practical everyday use of distance.
Common mistakes
Incorrect:This soup is gooder than the one I had yesterday.
Correct:This soup is better than the one I had yesterday.
good does not form its comparative with -er; its comparative is the separate word better.
Incorrect:My new phone is more good than my old one.
Correct:My new phone is better than my old one.
For an ordinary comparison of the quality of two phones, use better.
Incorrect:The traffic today is badder than yesterday.
Correct:The traffic today is worse than yesterday.
bad, like good, does not form an -er form; its comparative is the separate word worse.
Incorrect:Her results were more bad than last term's.
Correct:Her results were worse than last term's.
The form needed in an ordinary comparison of results is worse.
Incorrect:This hotel is more better than the last one.
Correct:This hotel is better than the last one.
In a standard comparison, better already means “better”, so more is unnecessary. For emphasis, you can say much better.
Incorrect:The station is farer from here than the airport.
Correct:The station is further from here than the airport.
far does not take -er; its comparative is the separate form farther/further (both are acceptable here).
