What does - ively -ive-ate means as a suffix?

Answer 1

Each allows the base word to be used in a different context.

Using -ively makes an adverb, or something that describes an action.

Using -ive makes an adjective, as in 'ameliorative'.

Using -ate makes a verb, as in 'activate'.

Answer 2

The suffix "-ively," when added to a word, typically means "in a certain manner" or "related to." The suffix "-ive-" is often used to form verbs meaning "to make or become." When combined, they create a new verb form that describes an action being done in a specific manner or way.
