-ment (act or result of)
-ment
Makes a noun from a verb.
Kabir's improvement in maths pleased his teacher.
Enjoyment
The pleasure of enjoying something.
Rohan read the comic purely for enjoyment.
Argument
A disagreement, or reasons for a view.
Priya made a strong argument for a longer lunch break.
Remember: Usually just add -ment: enjoy → enjoyment. Trap: argue drops its e, so it's argument. Judgement is the usual British spelling; judgment is also correct.
