Nominalization: Turning Verbs into Nouns

Overview

Nominalization is the process of converting a word from another grammatical category, most commonly a verb or an adjective, into a noun. The result is an abstract noun that carries the meaning of the original word but functions as a noun in the sentence. Decide becomes decision. Develop becomes development. Accurate becomes accuracy. Each of these shifts transforms an action or a quality into a concept that can be named, quantified, modified, and positioned anywhere a noun can go.

Nominalization is not a grammatical error or a stylistic trick. It is a fundamental feature of academic, professional, and formal written English, and understanding it is essential for learners at the C1 level who need to read, write, and interpret complex texts across disciplines. A learner who cannot recognise nominalized forms will misread dense formal prose. A learner who cannot produce them will struggle to achieve the register expected in academic and professional writing.

The process carries real tradeoffs. Nominalization compresses information and raises the register of a text, but overuse can make writing abstract, impersonal, and difficult to follow. This lesson covers both how nominalization works and when it is appropriate to use it.

How Nominalization Works

In a sentence built around an action verb, the verb carries the main meaning and usually takes a subject and sometimes an object.

When these sentences are nominalized, the verb is converted into a noun and the action becomes a concept. The sentence structure changes significantly: the nominalized noun takes on the role of subject or object, and a lighter verb such as make, reach, conduct, or result in often replaces the original action verb.

The nominalized versions shift the emphasis from who did something to what was done, making them more impersonal and abstract. This is precisely the quality that makes them prevalent in formal writing, where the process or outcome matters more than the agent performing it.

Suffix Patterns for Forming Nouns From Verbs

The most systematic way to learn nominalization is to study the suffixes that convert verbs into nouns. Several suffixes are highly productive, meaning they apply to a large number of verbs and generate reliable nominalized forms.

Suffix: -tion / -sion / -ation / -ition

This is the most common suffix group for converting verbs into abstract nouns. The exact ending depends on the spelling and sound of the base verb.

Suffix: -ment

This suffix attaches to many verbs and produces nouns that refer to a process, result, or state.

Suffix: -ance / -ence

These suffixes often convert verbs or adjectives into nouns expressing a state, quality, or ongoing condition.

Suffix: -al

This suffix converts several common verbs into nouns, particularly those describing a formal process or event.

Suffix: -ure

A smaller but important group of verbs converts with this suffix.

Forming Nouns From Adjectives

Nominalization also applies to adjectives, converting qualities into abstract nouns.

The resulting nouns allow a writer to discuss a quality as a standalone concept rather than attaching it as a descriptor to a noun. "She is accurate in her calculations" becomes "The accuracy of her calculations impressed the audit team" — accuracy now functions as the subject of the sentence.

Why Nominalization Is Used in Formal Writing

Nominalization serves several communicative purposes that explain its prevalence in academic, legal, scientific, and professional texts.

It raises the register and formality of a passage. Verbs feel active and conversational. Nouns feel measured and authoritative. A report that says the committee decided sounds more informal than one that says the committee's decision.

It allows information to be compressed. A nominalized noun can hold what would otherwise require a full clause.

It removes or backgrounds the agent, which is useful when the identity of who performed an action is unknown, unimportant, or deliberately not stated.

It also creates noun phrases that can be easily modified with adjectives and prepositional phrases, giving writers greater structural flexibility: "The rapid development of renewable energy technologies in the last decade has transformed the sector."

When Nominalization Becomes a Problem

Despite its legitimate uses, excessive or unnecessary nominalization produces writing that is difficult to read and often obscures meaning. The most common symptom is a sentence dense with abstract nouns, weak verbs like make, give, carry out, and conduct, and very little sense of who is doing what to whom.

The test is whether the nominalization serves a clear purpose: compression, formality, agent removal, or structural flexibility. If the sentence is clearer and equally appropriate with a verb, the verb is usually the better choice.

Comparing Verb-Based and Nominalized Sentences

Common Mistakes to Avoid

Using the Wrong Suffix

Different verbs take different suffixes, and applying the wrong one produces a non-word.

Nominalizing Every Verb in a Sentence

Stacking multiple nominalized nouns in a single sentence produces a passage that is technically grammatical but practically unreadable. Each nominalization removes a verb, and removing too many verbs drains the energy from a sentence.

Forgetting the Article Before a Nominalized Noun

Nominalized nouns are abstract nouns that behave like other nouns in terms of article use. When a specific instance is referenced, the definite article the is usually required.

Confusing the Noun Form With the Verb or Adjective Form

Because nominalized nouns are closely related to verbs and adjectives, learners sometimes use the verb or adjective form in a position where the noun is required.

Using Nominalizations in Informal Contexts

Nominalization belongs to formal and academic registers. Using heavily nominalized language in casual conversation or informal writing sounds stiff and unnatural.

In a formal report, "The decision to attend was made following a review of the agenda" is appropriate. In conversation, it is not.

Spelling Errors in Nominalized Forms

Several nominalization suffixes involve spelling changes at the boundary between the base word and the suffix. Doubling consonants, dropping final e, and changing y to i are among the most common adjustments.

Practice Exercises

Exercise 1: Form the Noun

Convert each verb or adjective into its nominalized noun form using an appropriate suffix.

1. investigate
2. achieve
3. appear
4. refuse
5. accurate
6. develop
7. persist
8. responsible
9. approve
10. free

Exercise 2: Rewrite Using Nominalization

Rewrite each sentence so that the underlined verb or adjective is nominalized. You may need to restructure the sentence.

1. The scientists discovered a new compound in the deep ocean.
2. The board approved the merger after weeks of negotiation.
3. She was patient throughout the entire process.
4. The government failed to respond within the required timeframe.
5. Researchers developed a new approach to treating the condition.

Exercise 3: Identify Overuse and Rewrite

Each sentence overuses nominalization. Rewrite it to be clearer and more direct without losing any essential meaning.

1. There was a failure on the part of the team in the achievement of the completion of the project on time.
2. The implementation of the suggestion for the improvement of the organisation of the office led to an increase in the satisfaction of the employees.
3. An examination of the data resulted in the identification of a pattern in the distribution of the results.

Exercise 4: Correct the Mistake

Each sentence contains one error related to nominalization. Rewrite the sentence correctly.

1. The decidement to close the branch was announced on Friday.
2. Her improve in the second assessment was remarkable.
3. Failure of the bridge was attributed to poor maintenance.
4. The develop of the new software took three years.
5. His arguement was dismissed by the panel.

Summary

Nominalization is one of the defining features of formal English. The skill lies not just in knowing how to form nominalized nouns but in knowing when they serve the writing and when they obstruct it. Used with purpose, nominalization compresses, elevates, and focuses. Used without judgement, it makes writing harder to understand than it needs to be.
