What is a nominalisation chain?
Nominalisation turns an action or quality into a noun: instead of the council decided, we can say the council's decision. When another action noun specifies that noun, and a third specifies the second, a chain emerges: a head noun with prepositional phrases nested inside one another.
This rule is not about forming nouns from verbs or adjectives. Its focus is what happens when several action nouns occur together: how to read the group, how many links a reader can follow, and how to replace unnecessary ones.
In scientific, legal, and administrative writing, chains pack considerable information into one subject. The cost is that each new link requires the reader to retain another relationship. The goal is balance rather than density for its own sake.
noun + of / in / for / on… + noun phrase with further specification
- NP / noun phrase —
- A noun phrase: a noun with its dependent words, such as the new student; the pattern treats it as one group of words.
- noun —
- A word naming a person, thing or idea: student, book, happiness.
The review of the rules for the allocation of nursery places is under way.
The review of the rules for the allocation of nursery places is under way.
Three links: of the rules → for the allocation → of nursery places. The head noun is review.
A study of rainfall patterns in the valley continues.
A study of rainfall patterns in the valley continues.
Two links: of rainfall patterns → in the valley. This is a manageable, readable chain.
The extension of the runway at the regional airport was approved.
The extension of the runway at the regional airport was approved.
Two links with different prepositions, of and at: a chain need not consist entirely of of-phrases.
Reading a chain: the head noun and its links
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 renewal of the contracts of the cleaners by the hospital was criticised.
The renewal of the contracts of the cleaners by the hospital was criticised.
The head is singular renewal, so the verb is was. Expanded: the hospital renewed the cleaners' contracts.
Increases in the price of tickets for the festival worry the organisers.
Increases in the price of tickets for the festival worry the organisers.
The head is plural increases, so the verb is worry, even though the nearest noun, festival, is singular.
How many links can the reader follow?
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.
The delay in the approval of the budget for the new stadium annoyed fans.
The delay in the approval of the budget for the new stadium annoyed fans.
Three specifications using in, of, and for. The relationships are fairly clear here, but the number of links alone does not guarantee readability.
The report of the review of the plans of the committee of the council of the district was lost.
The report of the review of the plans of the committee of the council of the district was lost.
Five links: the sentence is grammatical, but readers can lose track of what each of-phrase belongs to.
The report on the review of the district council committee's plans was lost.
The report on the review of the district council committee's plans was lost.
The same meaning: a possessive and a compound noun phrase reduce the chain to two links.
Why dense chains become difficult: ambiguity and hidden agents
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 distrust of the voters grew.
The voters' distrust increased, or distrust directed towards the voters increased.
Ambiguous: the voters distrusted someone, or someone distrusted the voters. You can clarify it with the voters' distrust of the government.
The reduction of the budget followed the review of the contracts.
The reduction of the budget followed the review of the contracts.
Neither action's agent is named. Without extra information, expand the sentence passively: The budget was reduced after the contracts were reviewed.
Method 1: possessives and compound noun phrases
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.
The university's policy on the assessment of coursework was revised.
The university's policy on the assessment of coursework was revised.
The owner, the university's, precedes the noun instead of forming an of the university phrase, removing one link.
The flood risk management strategy was published in May.
The flood risk management strategy was published in May.
Three noun modifiers before the head strategy form a compact label. Its usefulness depends on the reader's familiarity with the topic.
Method 2: appropriate prepositions instead of repeated of
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.
An interest in the history of the region grew among students.
An interest in the history of the region grew among students.
In introduces the object of interest; of relates the history to the region.
A ban on the sale of fireworks to children was introduced.
A ban on the sale of fireworks to children was introduced.
On follows ban, of follows sale, and to introduces the recipient: three different prepositions in one phrase.
Method 3: restore a verb or split the sentence
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 expulsion of the student from the club was followed by the resignation of two members.
The expulsion of the student from the club was followed by the resignation of two members.
Two noun phrases: the density is moderate, but the agent of the expulsion is not named.
The club expelled the student, and two members resigned.
The club expelled the student, and two members resigned.
The verbs express the actions more directly. The club names the agent of the expulsion; add this detail only if it is known from the context. To preserve an explicit sequence, then can be added before two members resigned.
Agreement and determiners in a chain
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.
The reopening of the east galleries was delayed.
The reopening of the east galleries was delayed.
The head is singular reopening, so use was, not were, even though the nearest word, galleries, is plural.
The causes of the failure of the experiment remain unclear.
The causes of the failure of the experiment remain unclear.
The head is plural causes, so use remain. The appears before the head noun and before failure.
Register: when a chain is appropriate
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.
The cancellation of the ferry service followed a deterioration in the weather.
The cancellation of the ferry service followed a deterioration in the weather.
A formal version with two noun phrases, suitable for a report.
They cancelled the ferry after the weather got worse.
They cancelled the ferry after the weather got worse.
The simpler version with verbs preserves the event sequence. Followed alone does not assert a cause, so because would add a separate causal inference.
The limits of this rule
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.
The committee published its findings on the funding of rural libraries.
The committee published its findings on the funding of rural libraries.
Two nominalised actions occur together with one main verb. The chain is short and does not need shortening.
Common mistakes
Incorrect:The enforcement of the new rules in the three offices have been delayed.
Correct:The enforcement of the new rules in the three offices has been delayed.
The verb agrees with the singular head noun enforcement, not the nearby offices.
Incorrect:An investigation into cause of the fire was requested.
Correct:An investigation into the cause of the fire was requested.
In this sentence, cause is specified by of the fire and refers to the particular cause being investigated, so the is needed.
Incorrect:There was a sharp fall of the interest of tourists in the old town.
Correct:There was a sharp fall in the interest of tourists in the old town.
After fall, in introduces the measure that changes. Automatically using of creates the wrong relationship.
Incorrect:Their dependence from foreign funding is growing.
Correct:Their dependence on foreign funding is growing.
Dependence takes on; from is an error here, not an alternative.
Incorrect:The teachers' of the school performance improved.
Correct:The school teachers' performance improved.
Place the possessive ending after the complete possessor phrase: the school teachers' performance or the teachers of the school's performance. You cannot insert of the school between teachers' and the rest of the phrase as in the incorrect example.
