Suffix · forms nouns
Turns a verb into the noun that names the action, process or its result: develop becomes development.
Written by Bryan López, English teacher · Updated
The suffix -ment takes a verb and creates the noun that names the action, process or its concrete result. From "develop" you get "development"; from "agree" you get "agreement"; from "pay" you get "payment". It is the second most common noun-forming suffix after -tion. The key difference: -tion tends to pair with Latin-origin verbs, while -ment pairs more often with native English and French-origin verbs.
Unlike -tion (which usually names an abstract action), -ment often names both the process and the concrete result or document. agreement = the process of agreeing AND the signed document. payment = the act of paying AND the money handed over. statement = the act of stating AND the written record. Always check context to see whether a -ment word refers to the process or the outcome.
The rule is straightforward: verb + ment. No tricky spelling changes.
In most cases just attach -ment to the verb. The silent -e is kept in nearly all words (move → movement, achieve → achievement), though "judge → judgment" is a classic exception. When you see -ment, strip it off to find the verb hidden inside.
-ment/mənt/ · soft, unstressed 'munt'

No extra -e-. Just verb + ment: develop + ment = development.
The suffix is -ment, not -iment. move → movement.
agree → agreement. The -e in "agree" is kept, then add -ment: agree + ment = agreement.
A trick to remember it
Think of development: verb + -ment = the action or its result. Develop gives development, agree gives agreement.
