A suffix is a letter or a group of letters attached to the end of a word to form a new word or to change the grammatical function (or part of speech) of the word. For example, the verb read is made into the noun reader by adding the suffix -er. Similarly, read is made into the adjective readable by adding the suffix -able.

Understanding Suffix Meanings

Understanding the meanings of the common suffixes can help you figure out the meanings of new words you encounter.

In some cases, the spelling of a root or base word changes when a suffix is added. For example, in words ending in y preceded by a consonant (such as the noun beauty and the adjective ugly), the y may change to an i when a suffix is added (as in the adjective beautiful and the noun ugliness). In words ending in silent -e (such as use and adore), the final -e may be dropped when the suffix that's added begins with a vowel (as in usable and adorable). 

As with all spelling rules, there are exceptions. Not all suffixes can be added to all roots. For example, the adjective beautiful is formed by adding the suffix -ful to the noun beauty, and the noun ugliness is formed by adding the suffix -ness to the adjective ugly.

Also note that a suffix may have more than one meaning. With adjectives and adverbs, for instance, the -er suffix usually conveys the comparative meaning of "more" (as in the adjectives kinder and longer).

But in some cases, the -er ending can also refer to someone who performs a particular action (such as a dancer or builder) or to someone who lives in a particular place (such as a New Yorker or a Dubliner).
