what is the meaning of the suffix

A suffix is a letter or group of letters added to the end of a word to change its meaning or grammatical form.

Examples:

• -ed turns a verb into past tense, as in walked.

• -ly can change an adjective into an adverb, as in quickly.

• -s can show plural, as in cats.

In short, a suffix goes at the end of a word, while a prefix goes at the beginning.
