What you'll learn

By the end of this lesson, you'll be able to turn verbs and adjectives into nouns to make your writing more formal.

When do I use it?

Nominalisation replaces a verb or adjective with a noun, making text more abstract and formal:

  • "They analysed the data" → "The analysis of the data revealed..." (verb → noun)
  • "The price increased" → "There was an increase in the price." (verb → noun)
  • "The report is reliable" → "The reliability of the report is clear." (adjective → noun)

Common noun endings: -tion/-sion, -ment, -ness, -ity, -ance/-ence, -al.

How do I form it?

Structure

verb + -tion/-sion/-ment → noun adjective + -ness/-ity/-ance → noun

  • decide → decision, explain → explanation, improve → improvement
  • happy → happiness, possible → possibility, important → importance
  • "Their decision to invest was wise." (from decide)
  • "The possibility of failure worried us." (from possible)

Common mistakes for Spanish speakers

Warning

Spanish nominalises with the same endings (-ción, -dad, -encia), so the concept is easy — the trap is choosing the WRONG English ending: "existance" is wrong (existence), "necesarity" is wrong (necessity), "developement" is wrong (development). Learn the correct noun for each word. Also, nominalisation can make text heavy — use it in formal writing but keep verbs in speech: prefer "we analysed" over "we performed an analysis of" in conversation.

Hint

Verb/adjective + -tion/-ment/-ness/-ity → noun. Check the spelling of each one.
