Suffixes · Year 2

A suffix is a group of letters added to the end of a word. It can change the meaning (hope → hopeless) or the word class (the adjective kind becomes the noun kindness or the adverb kindly). The word you start with is the root word.

  • -ly makes adverbs from adjectives: quick → quickly. -er can make a person: teach → teacher.
