Key Points:
The suffix “-tion” is used to form nouns from verbs, typically indicating an action, process, or state.

The spelling of the base verb often changes slightly when adding “-tion” (e.g., dropping or replacing letters).

Not all verbs can be converted to nouns using “-tion”; some require other suffixes like “-ment” (e.g., enjoy → enjoyment) or “-ance” (e.g., perform → performance).
