Cultural definitions for suffix


A letter or a group of letters added to the end of a word to change its meaning. For example, adding the suffix -ter to the adjective hot turns it into the comparative adjective hotter, and adding the suffix -ly to the adjective quick turns it into the adverb quickly. Other examples of words with suffixes are: “willing,” “management,” “serviceable,” “harmonize,” and “joyful.” (Compare prefix.)
