Nominalisation: making a process the topic without changing the facts
1. The process becomes the subject of discussion
In a verb-based construction, we primarily report who does what. In a nominalised construction, we name the action itself so that it can be compared, evaluated, explained, or made the topic of the next sentence. The grammatical metaphor here is not a poetic image: the event is grammatically presented as a “thing”, although it remains an event.
Compare The panel decided yesterday and The panel’s decision yesterday. The second fragment is not a complete statement: it needs a continuation. Nominalisation is not simply a change of ending, but a restructuring of the whole sentence. A noun can be the subject, object, or part of a prepositional phrase.
who + verb + what → action noun + participants / object + predicate of a new sentence
- verb / V —
- A word for an action or state, such as work or be. The pattern determines its form.
- object / O —
- Who or what an action affects: in I read a book, a book is the object.
- noun —
- A word naming a person, thing or idea: student, book, happiness.
The board postponed the vote. This postponement gave members another day to read the report.
The board postponed the vote. This postponement gave members another day to read the report.
Postponement names an action already reported and makes it the topic of the second sentence; the consequence is directly asserted by the writer.
We discussed the expansion of the evening service.
We discussed the expansion of the evening service.
Expansion is the object of discussed. Discussing an expansion does not by itself prove that the service has already been expanded: the context determines the status of the event.
2. Word formation and the grammar of the noun phrase
Common pairs include: revise → revision, improve → improvement, refuse → refusal, discover → discovery, grow → growth. There is no single universal suffix. Some words do not change form: a change / to change, a delay / to delay. Check not only the ending but also the intended meaning: organisation can refer to the process of organising or to an institution.
After a verb is changed into an ordinary noun, its dependent words are restructured: expand rapidly → rapid expansion; examine the records → examination of the records. The article, possessive determiner, number, and preposition are chosen according to the meaning of the whole group. Do not combine the directly with the possessive determiner their: their decision, not the their decision.
Not all abstract nouns are uncountable. Two separate checks can be two inspections, whereas general increase is growth. Make the predicate agree with the head noun, not with the nearest word after of: the inspection of two lifts was, but two inspections were.
The gradual expansion of the service took three years.
The gradual expansion of the service took three years.
The adjective gradual describes the noun expansion. Of the service identifies what was expanded; took preserves the past time frame.
Two inspections of the bridge were completed in May.
Two inspections of the bridge were completed in May.
Two inspections means two events, so the plural form were is used. Nominalisation should not erase the number of separate actions.
3. -ing forms can also name a process
The ending -ing is not a sign of unsuccessful nominalisation. Comparing the results carefully takes time is a normal construction: the -ing group occupies the subject position, but internally retains verb complementation, a direct object, and the adverb carefully. By contrast, the careful comparison of the results has a clearly noun-based structure.
Noun forms ending in -ing are also possible: the careful handling of the samples. Therefore, the whole construction matters, not a rule that “-ing is forbidden”. Rapid industrialising can name a process, although industrialisation is more often the established term in the relevant text. An unusual collocation, a grammatical error, and failure to use a specific derived noun are different things.
For practical writing, choose a natural form and a consistent internal structure. If the task explicitly asks for comparison, that is the word-formation target of the exercise; acceptable comparing does not therefore become ungrammatical in the language.
Checking the figures carefully took an hour.
Checking the figures carefully took an hour.
Checking has the direct object the figures and the adverb carefully: this is a verb-based structure inside a group that functions as the subject.
The careful checking of the figures took an hour.
The careful checking of the figures took an hour.
Here checking has noun-like marking: the, the adjective careful, and of. Both examples are grammatical and preserve the duration.
4. Who acted, and what was the action directed at?
Nominalisation allows us not to name the agent, but it does not require us to hide the agent. If the agent is known and relevant to the reader, retain it through a possessive group, by, or a separate part of the sentence. The agency’s inspection of the site clearly distinguishes the inspector from the object being inspected.
Of-groups are sometimes ambiguous. The criticism of the director may mean criticism directed at the director; without enough context, the reader cannot always confidently recover the roles. For precise editing, name the critic and the target: the residents’ criticism of the director. If the agent has not been established, do not invent one for the sake of an active sentence or a clearer noun phrase.
An impersonal tone does not guarantee objectivity. The regrettable rejection of the plan already contains the evaluation regrettable. The rejection of the plan hides who rejected the plan if this is not clear from the context. Responsibility and evidential support belong to the content, not to the part of speech.
The residents’ rejection of the proposal surprised the committee.
The residents’ rejection of the proposal surprised the committee.
Residents’ names those who rejected the proposal; committee names those who were surprised by it. The roles must not be switched during paraphrasing.
The deletion of the files occurred overnight; the person responsible has not been identified.
The files were deleted overnight; the person responsible has not been identified.
The agent is genuinely unknown. Nominalisation is appropriate here, and the absence of an identified agent is stated directly.
5. Time, possibility, and negation do not disappear
A noun does not itself have grammatical tense. Past time, duration, incompleteness, or possibility must be preserved in the predicate and dependent words: the ongoing review, a possible reduction, the attempt to reopen. Check that the new sentence does not assert completion of a process that is still continuing.
Aim to, try to, and work towards describe a goal or effort, not a guaranteed result. We aim to reduce delays can be expressed as Our aim is a reduction in delays. Our reduction in delays, without other qualifications, may already present the reduction as a fact. Similarly, may reject expresses a possible rejection, not necessarily a rejection that occurred.
Preserve the scope of negation and the degree. Did not approve does not equal refused to approve: the second includes a deliberate decision to refuse. A slight improvement cannot be changed into a dramatic improvement. Do not infer a motive, cause, evaluation, or scale for the sake of impressive noun-based style.
The team is still reviewing the policy. The team’s review of the policy is still in progress.
The team is still reviewing the policy. The team’s review of the policy is still in progress.
The second sentence does not make review a completed result: still in progress preserves the state of the work.
The council may postpone the hearing. A postponement of the hearing by the council is possible.
The council may postpone the hearing. A postponement of the hearing by the council is possible.
Possible conveys the uncertainty of may. The agent, council, is retained; neither sentence reports that the decision has already been made.
6. Cohesion: name the previous idea accurately
This reduction, these changes, and that refusal can pick up a previous action and make it a known topic of a new sentence. This makes it easier to move from information already stated to new information. Repeating the key noun is often more precise than using this without naming what it refers to.
The summarising noun must match the previous content. If the team merely proposed changes, this implementation would incorrectly present them as implemented. If three different inspections took place, these inspections preserves the plural meaning. Do not call a neutral change failure or success if that evaluation has not yet been made.
The laboratory repeated the test twice. These repetitions produced the same reading.
The laboratory repeated the test twice. These repetitions produced the same reading.
These repetitions refer specifically to the two repeated test performances, not to an additional action.
The union proposed a shorter working week. This proposal has not yet been discussed by management.
The union proposed a shorter working week. This proposal has not yet been discussed by management.
Proposal preserves the status of the proposal. Change or implementation without clarification could prematurely present it as completed.
7. Connecting events does not allow you to invent causation
Nominalised processes are convenient to connect through followed, coincided with, resulted from, or caused. However, these predicates encode different logical relationships. After does not mean because of; simultaneity does not mean consequence; despite marks concession, not cause.
If the source information asserts only the sequence of events, choose followed or after. Led to or caused are appropriate only when a causal relationship has already been established. Even a grammatically flawless sentence can be an inaccurate paraphrase because it makes a stronger inference.
The release of the report followed the director’s resignation.
The release of the report followed the director’s resignation.
Followed reports the order of events. The sentence does not explain why the report was released and does not make the resignation the cause.
A fault in the alarm caused the cancellation of the rehearsal.
A fault in the alarm caused the cancellation of the rehearsal.
Caused directly names the reason. This combination is appropriate if the fault really was the cause of the cancellation in the source information.
8. Choose density for the reader, not for formality’s sake
In an analytical paragraph, comparison or reduction can help maintain one topic. In a short request, a verb often shows the required action more quickly. Please confirm your address and Please provide confirmation of your address are grammatical; the second option is not better merely because of confirmation.
It is not necessary to nominalise every verb. Long chains such as the evaluation of the implementation of the revision of the procedure may force the reader to reconstruct several embedded actions. Keep one useful process noun and distribute the remaining information. This is a limit on the use of nominalisation, not a general ban on noun-based style.
Before finishing, reread the sentence: is it clear who acted; what happened, is continuing, or is only possible; what relationship exists between the events; and why exactly this action was named with a noun? If the answer is unclear, return some of the information to a verb-based construction.
Please attach the receipt before you send the form.
Please attach the receipt before you send the form.
For a direct instruction, the two required actions are immediately visible. There is no need to add the attachment of or the submission of merely to sound formal.
The evaluation covers two changes. It examines how the team introduced them.
The evaluation covers two changes. It examines how the team introduced them.
Evaluation remains a useful topic noun, but the subordinate clause clearly names the action and the agent. Balance does not require eliminating all nominalisations.
Common mistakes
Incorrect:The rapidly expansion of the archive continued.
Correct:The rapid expansion of the archive continued.
The adjective rapid is needed before the noun expansion. The adverb rapidly is natural with the verb expanded, but not as this direct modifier of the noun.
Incorrect:Their refusal negotiate delayed the meeting.
Correct:Their refusal to negotiate delayed the meeting.
The noun refusal retains the infinitive complement to negotiate. Omitting to breaks the construction.
Incorrect:The their decision surprised us.
Correct:Their decision surprised us.
The possessive determiner their already determines decision; the cannot stand directly before their in this noun phrase.
Incorrect:The deterioration of the two roofs are visible.
Correct:The deterioration of the two roofs is visible.
The head word of the subject, deterioration, is singular. The plural noun roofs inside the of-group does not determine the form of the predicate.
Incorrect:The careful examination the evidence took two days.
Correct:The careful examination of the evidence took two days.
After examination, the object is expressed with of. A direct object is possible in examining the evidence, but not in this group with an ordinary noun.
