Nominalisation (Academic Noun Style)
Nominalisation turns a verb or adjective into a noun — decide becomes decision, happy becomes happiness — so an idea can head the sentence. It makes writing denser and more formal, which suits academic and official texts.
Level: C1. You already write clear sentences with verbs. Nominalisation is the next move up: you turn the verb or adjective into a noun so the idea becomes a thing you can name, count and build a formal sentence around.
The rule
Nominalisation means making a noun out of a word that is normally a verb or an adjective. Decide (verb) becomes decision (noun); happy (adjective) becomes happiness (noun). The action or quality is still there, but it is now packaged as a noun phrase — a group of words that works as a single noun.
Why bother? Because a noun can sit in the subject slot and carry a lot of information. Compare They decided to close the factory, and this made many people angry with The decision to close the factory caused anger. The second version is shorter, more abstract and more impersonal. That density is exactly what academic, scientific, legal and official writing wants.
Most nominalisations are built with a suffix: an ending added to the base word. The commonest are -tion/-sion (react → reaction), -ment (develop → development), -ance/-ence (refer → reference), -ity (able → ability), -ness (happy → happiness) and -al (arrive → arrival). Some words change their vowel or stem instead (strong → strength, lose → loss, choose → choice).
The cost is clarity. A noun hides who did what: A decision was taken does not tell you who decided. Good C1 writers use nominalisation to sound formal and to connect ideas, but they stop before the sentence becomes a wall of abstract nouns that no reader can unpack.
Transformation forms
| Base word | Word class | Nominalised noun | Typical ending |
|---|---|---|---|
| decide | verb | decision | -sion |
| develop | verb | development | -ment |
| arrive | verb | arrival | -al |
| fail | verb | failure | -ure |
| argue | verb | argument | -ment |
| analyse | verb | analysis | stem change |
| lose | verb | loss | irregular |
| happy | adjective | happiness | -ness |
| able | adjective | ability | -ity |
| strong | adjective | strength | vowel change |
| wide | adjective | width | vowel change |
| poor | adjective | poverty | -ty |
Example sentences
- The decision was made after a long discussion.decide to decision, discuss to discussion: two nouns carry the action.
- Her analysis of the data was thorough.analyse to analysis, heading the subject of the sentence.
- The failure of the experiment surprised no one.fail to failure lets the idea become the subject.
- Government investment in housing has increased.invest to investment packs the action into one noun.
- The refusal to cooperate delayed the project.refuse to refusal; note the following to-infinitive.
- There has been a significant improvement in air quality.improve to improvement, with the preposition in.
- The development of the vaccine took years.develop to development, a classic -ment noun.
- His arrival went unnoticed.arrive to arrival, an -al noun as subject.
- The assessment of risk is central to the study.assess to assessment.
- Their reaction to the news was calm.react to reaction; the preposition is to.
- The width of the bridge was measured first.wide to width: an adjective turned into a noun with a vowel change.
- Poverty remains the main obstacle to growth.poor to poverty, grow to growth: two nominalisations.
- The accuracy of the results was questioned.accurate to accuracy, an -acy noun.
- Her happiness was obvious to everyone.happy to happiness, an -ness noun.
- The strength of the argument lies in its evidence.strong to strength, argue to argument.
- An explanation was given for the delay.explain to explanation; the agent is hidden on purpose.
- The introduction of the policy caused debate.introduce to introduction.
- The loss of data was a serious problem.lose to loss, an irregular form.
- Knowledge of the subject is assumed.know to knowledge, an irregular noun.
- The choice between the two options was difficult.choose to choice, an irregular form.
- The reduction in costs followed a review of spending.reduce to reduction, review and spend nominalised: dense but still readable.
Common mistakes
- ❌ The implementation of the reduction of the allocation of resources was slow. → ✅ Resources were allocated more slowly after the cuts. Three stacked nouns are unreadable; unpack them into verbs.
- ❌ the analyse of the data → ✅ the analysis of the data. You need the noun analysis, not the verb analyse.
- ❌ He gave an explainment. → ✅ He gave an explanation. Use the correct suffix; explainment is not a word.
- ❌ a big improvement of the situation → ✅ a big improvement in the situation. Many nominalisations take a fixed preposition (improvement in, reaction to, increase in).
- ❌ A decision was taken, which upset everyone, so nobody knew who was responsible. → ✅ The board took the decision, which upset everyone. If the reader needs the agent, name it rather than hiding it in a passive nominal.
- ❌ The developmentation of the plan… → ✅ The development of the plan… Do not double-mark a word that is already a noun.
A short conversation
A: Your report keeps saying we decided and we found. Can you make it sound more academic? B: So I turn the verbs into nouns? A: Exactly. We decided becomes the decision was taken, and we found becomes the findings show. B: Got it — but you warned me not to overdo it. A: Right. One clear noun phrase beats three stacked nouns that nobody can read.
Usage notes
- Where it belongs. Nominalisation is a feature of written, formal registers: research articles, reports, policy, law. In conversation, English strongly prefers verbs — They cut the budget, not The budget reduction was effected.
- Choosing the agent. Nominalisation often lets you drop the agent, like the passive. That is useful for an impersonal tone, but dishonest if you hide responsibility that the reader has a right to know.
- Fixed prepositions. Learn the preposition with the noun: an increase in, a reaction to, a solution to, a reason for, knowledge of, an effect on.
- Linking ideas. A nominalisation can repackage a whole previous sentence as the subject of the next: The factory closed. This closure cost 300 jobs. This is a key tool for cohesion in academic prose.
Compared with…
- Hedging and cautious language is the other main academic-style tool. Where nominalisation compresses information into nouns, hedging softens a claim so you do not overstate it, using modals and adverbs: This may suggest that…, The results appear to indicate…. The two often work together in the same formal sentence. See Hedging and Cautious Language.
- Prerequisite — articles. Nominalised nouns need the right article: the decision (specific), a decision (one of several), decisions in general (zero article). Review Advanced Article Use.
- Prerequisite — subject–verb agreement. A long noun-phrase subject still has to agree with its verb: The analysis of the samples was completed (head noun analysis, singular). See Subject–Verb Agreement.
