Nominalisation

Nominalisation is common in formal and academic writing: it lets you name an event with a noun phrase and make it the subject or object of a new sentence. Because the government invested in the port, exports grew has two clauses with verbs; The government's investment in the port led to export growth connects two events expressed as nouns through the verb led to.

Nominalisation also lets you omit the agent when it is unimportant or clear from context: A thorough investigation began does not require a by whom phrase, whereas the verbal version X investigated thoroughly grammatically requires a subject.

Common productive suffixes include -tion/-sion (introduce→introduction, expand→expansion, discuss→discussion), -ment (develop→development, require→requirement), -al (refuse→refusal, arrive→arrival, propose→proposal), -ance/-ence (perform→performance, differ→difference, exist→existence), and -ure (fail→failure, expose→exposure, close→closure).

There is no formula that selects the suffix for every verb; learn each word's form individually. Two similar verbs may take different suffixes: refuse→refusal, but confuse→confusion, not confusal.

Some verbs change their stem instead of simply adding a suffix: decide→decision (not decideation or decidement), choose→choice, know→knowledge, lose→loss, prove→proof, succeed→success, believe→belief, grow→growth. These are another way of forming nouns, with each verb's corresponding noun learned individually.

Some verbs and nouns have identical spellings: increase, decrease, change, use, review, offer, cause, control. Their pronunciation or stress may differ, as with use and increase. For the ordinary noun meaning a rise, use increase rather than adding a suffix by analogy.

The original clause's subject becomes a possessive before the noun (the committee's decision) or a by phrase after it (the decision by the committee). The second is common when the agent matters but is not presented as the noun phrase's possessor, for example with a passive-like perspective. The original verb's object often becomes an of phrase (a review of the applications); verbs such as decide, refuse, fail, and attempt can produce nouns followed by an infinitive (a decision to cut costs, a refusal to comment).

If both subject and object are named, a common order is the + adjective + noun + of + object + by + subject: the careful analysis of the samples by the laboratory. Neither participant must always be named: omitting the subject (a thorough investigation began), or an object clear from context, is often natural.

An adverb describing the verb becomes an adjective before the nominalised noun: carefully examine → a careful examination; significantly improve → a significant improvement; rapidly expand → rapid expansion. The adjective usually drops -ly (careful, significant, rapid), but some pairs need a dictionary check rather than mechanical removal of the ending.

A manner adverbial can become an adjective: They analysed the data carefully last week → their careful analysis of the data last week. Time and place can also be retained, but do not necessarily become adjectives: last week remains a time expression after the event noun phrase.

Of is not a universal preposition. Learn a noun together with its meaning and typical complement: belief in the plan, response to a complaint, increase in prices, effect on sales. Often the preposition is retained: depend on → dependence on. However, solve the problem gives a solution to the problem. Solution of the problem is also possible, especially for the process of solving it; it should not be labelled an error.

Nominalisation is a register choice, not a correction of a grammatical error. The committee decided to cut the budget remains entirely correct in conversation, email, or a news report; the committee's decision to cut the budget is more characteristic of a report, academic article, or official document. Neither version is inherently better; choose the register that suits the situation.

Excessive nominalisation in successive sentences makes reading harder and sounds artificial even in formal writing. Experienced writers combine nominalised phrases with ordinary verb-based clauses instead of nominalising every action.

This rule does not cover chains of nominalisations in which one derived noun phrase is embedded inside another, such as the implementation of the reduction of the deficit; that is a separate, broader skill. It also excludes turning adjectives into nouns (reliable→reliability, complex→complexity), a different word-formation process with its own suffixes (-ity, -ness).

The passive voice (the budget was reduced) is related but separate: nominalisation removes the original clause's verb as a predicate rather than changing its voice. An -ing verb phrase used as a sentence subject (Reducing the budget was difficult) is also outside the main focus, although it is a valid, sometimes the only, way to nominalise a verb without a separate derived event noun (monitor→monitoring).

The most productive suffix for adjectives of Latin origin is -ity: dense → density, rare → rarity, flexible → flexibility. Adjectives in -able/-ible give -ability/-ibility, as in compatible → compatibility and available → availability; those in -ous often give -osity or -ity, as in generous → generosity and anonymous → anonymity. The suffix -ness attaches to simple and compound adjectives, especially those in -ful, -less, -ing and -ed: kind → kindness, helpful → helpfulness. Adjectives in -ive use both patterns, with the choice fixed for the word: effective → effectiveness, but active → activity and sensitive → sensitivity. Final -y changes to -i-: happy → happiness.

Adjectives in -ant/-ent change to -ance/-ence or -ancy/-ency: relevant → relevance, absent → absence, frequent → frequency, urgent → urgency. The choice between -ce and -cy is fixed for the individual word and sometimes reflects a difference in meaning: dependence is a state of dependence, while dependency can be a dependent territory or situation. Learn the suffix with the word rather than choosing by a formula; check uncertain forms in a dictionary.

Not every noun is formed by adding -ity or -ness. Learn complete pairs: true → truth, warm → warmth, broad → breadth, high → height, wise → wisdom, brave → bravery, safe → safety, difficult → difficulty. Sometimes the spelling of the stem changes; sometimes a different word is chosen for the intended meaning, as in fast → speed. Other derivatives may exist but have a different nuance or be much rarer.

A separate trap is a shift in meaning. Busyness names the state of being busy, while business means an activity, enterprise or commercial matter. Ill gives illness, referring to sickness rather than a bad or malicious quality. If a noun is familiar but its meaning is wrong, check whether it actually corresponds to the adjective you intend.

When the adjective is negative, the prefix carries over into the noun: impossible → impossibility, irrelevant → irrelevance, dishonest → dishonesty, unkind → unkindness. Sometimes un- in an adjective corresponds to in- in the noun because the noun is based on a Latin stem rather than the English word with un-: unequal → inequality. Check each pair in a dictionary instead of adding a suffix at random.

A negative noun expresses a lack or an opposite property, not simply ‘absence’: dishonesty is a trait, while absence is the fact of something or someone not being present. Such a noun can readily become the subject: the dishonesty of the contractor delayed the project.

The subject of the adjective clause becomes the complement of an of-phrase, as in the safety of the vaccine, or a possessive modifier, as in the vaccine’s safety. An of-phrase is more natural for long or inanimate subjects, while a possessive often suits short or personal ones. Other clause frames can also be transformed: how + adjective, as in How safe the vaccine is → the safety of the vaccine; so + adjective + that, as in so dense that few finished it → the sheer density of the text meant that few finished it; and it is + adjective + to-infinitive, as in It is necessary to document every decision → the necessity of documenting every decision.

Integrate the new noun phrase into a sentence through a predicate. For example, The text was so dense that few finished it → The density of the text meant that few finished it. The causal relationship is preserved here. The new verb does not have to be a linking verb such as be.

When an adverb previously modified a quality but must now modify a noun directly, the corresponding adjective is often needed: strikingly similar → striking similarity; increasingly dependent → increasing dependence. In increasingly dependence, the adverb has incorrectly been placed where an adjective belongs. Not every adverb in the sentence needs changing: what matters is the word it modifies.

Choose a natural combination with the new noun: very likely → high likelihood; very important → of great importance; extremely cautious → extreme caution. Not every pair can be formed mechanically: the choice of high, great, strong or another adjective depends on the noun. The findings are of great importance means that the findings are very important.

The adjective’s complement carries over, but not always unchanged: conscious of → consciousness of, able to → ability to, sensitive to → sensitivity to, dependent on → dependence on, responsible for → responsibility for. Sometimes the frame changes: different from → difference between, likely to → likelihood of + -ing, important to + infinitive → importance of + -ing. Possibility, likelihood and certainty can take a that-clause: the possibility that talks will fail.

The article depends on meaning and context. The importance of sleep names the particular property under discussion, but an of-phrase does not itself require the: Freedom of speech matters; Availability of water varies. Abstract nouns are often uncountable, and some also have countable meanings: a kindness is a kind act, and a difficulty is an individual problem. Check the usage of the particular word.

The noun phrase the volatility of the market is not a complete sentence on its own. It can be integrated as a subject or object: The volatility of the market worries investors. The predicate must convey the intended relationship, such as a cause, consequence or reaction.

A noun with this or that can summarise the previous idea: Border crossings remain unpredictable. This unpredictability raises costs for exporters. The reader sees which property is being discussed next. Avoid excessively long chains of nouns, but the number of verbs or clauses is not limited to one: this is a matter of clarity, not a grammatical prohibition.

Nominalisation is a choice associated with academic register, not a correction of an error: Experts doubted that the data were reliable remains perfectly good English. Dense sequences of nouns make a text harder to read, especially when the agent disappears. If the reader is not a specialist and an adjective is natural, consider keeping it. The test is whether the reader quickly understands what the sentence concerns and who or what is responsible for the situation.

This rule does not cover nouns derived from verbs, such as introduce → introduction, or chains of nested nominalisations. Nor does it cover nominal uses of adjectives such as the poor and the elderly, where the adjective appears without a suffix and denotes a group of people. Not every adjective has a convenient noun: the size of is more natural than uncommon bigness, and the height of is more natural than tallness.

Read the phrase from left to right. In this pattern, the first action noun is the head: it determines whether the verb is singular or plural and has its own determiner. Each following link answers a question about the preceding noun, such as of what, in what, for what, or by whom.

To check your understanding, expand the action nouns into sentences. If the agent is unnamed and unknown from the context, do not invent one: use a passive construction if necessary. Add a specific agent only when that information is available.

The noun nearest the verb does not control agreement; it merely ends the final link. Agreement with the nearest word is a particularly common mistake in long subjects.

The more nested specifications a phrase contains, the harder its relationships are to follow. After two or three links, reread the phrase to check clarity. There is no universal numerical limit: word length, familiarity with the concepts, and context also matter.

A long chain is not necessarily incorrect; it can be grammatical. The problem is that readers must hold all the relationships in mind and may not see which noun the final phrase modifies. Two or three links with a clear verb are preferable to six links with a weak predicate.

An action noun naturally has two sides: an agent and an object. The preposition of alone does not distinguish them. The same phrase can therefore have opposing readings: does the distrust of the voters mean that the voters distrust someone, or that someone distrusts the voters?

In a long chain, the agent often disappears altogether: the sentence describes events without saying who acted. Restore the agent by using a verb with a subject or naming the agent in a separate phrase, such as by the board or the board's.

The simplest way to remove a link is to put the owner or place before the noun: the policy of the university → the university's policy. Possessives are natural with people, organisations, and places.

Another option is a compound noun phrase: the strategy for the management of the risk of flooding → the flood risk management strategy. Noun modifiers are often singular, but established exceptions exist. Long groups without prepositions can also be hard to read, so check clarity rather than merely counting words.

A possessive does not automatically shorten every construction successfully. Do not mechanically change a lack of funding to funding's lack: the relationship and meaning may become unclear. Possessives with abstract nouns are possible in general; everything depends on the particular combination.

Not every action noun takes of. Learn the appropriate combination: interest in, ban on, answer to, need for, belief in, attitude to. A chain of different prepositions can be easier to read than a stack of identical of-phrases because each preposition signals the relationship involved.

A common mistake is to automatically attach of to every noun. Learn the noun with its preposition rather than treating of as a universal link.

If a possessive or compound noun cannot shorten the chain, turn one of its nominalised actions back into a verb. This creates a subject position and can make the agent visible.

Another technique is to split the sentence in two. A noun phrase in the second sentence, such as the expulsion or that withdrawal, summarises the first, allowing the new sentence to begin with a simpler construction. This creates cohesion between sentences without adding more links.

The verb agrees with the head noun, not the nearest word. Determiners depend on countability and specificity: the cause of the failure identifies a particular cause, but Funding of rural libraries remains limited is possible without the. An of-phrase does not automatically require an article.

The determiner in each nested link depends on meaning: the plan for the renovation of the stations, but a plan for renovation of stations in a general sense. These decisions accumulate within a chain, so check them individually.

Dense chains are characteristic of formal writing: reports, policies, research articles, and legislation. In a work chat, spoken explanation, or instruction, the reader needs to act quickly or follow speech, so verbs and short sentences usually work better.

Practise expressing the same content in two registers. Register is a choice for the reader, not simply a question of correctness.

This lesson does not teach noun formation from verbs or adjectives with -tion, -ment, or -ity; separate rules cover those patterns. We work with existing action nouns and how to connect them.

Other kinds of embedded noun-phrase structure—adjective order, relative clauses after nouns, and apposition—are not practice targets either. They appear only when they help shorten a chain.
