Usage

What does suffix mean? A suffix is a letter or group of letters placed at the end of a word to create a new word. For example, you can add the suffix -y to sleep to make sleepy or the suffix -er to loud to make louder. Suffixes are a handy tool of grammar that allows you to make a new word with a meaning that is closely related to the word the suffix is being attached to. Suffixes sometimes change the part of speech of the words they are added to. The verb create, for example, becomes the noun creation when you add the suffix -tion to it. To make create an adjective, you’d add the suffix -ive to make creative. Sometimes, a suffix changes the meaning of the word it is attached to. For example, the word defense means protection, but if you add the suffix -less, you end up with the adjective defenseless, which means unprotected.

Etymology

Origin of suffix

First recorded in 1595–1605; from New Latin suffixum, noun use of neuter of Latin suffixus, past participle of suffīgere “to attach on top of ,” equivalent to suf- suf- + fīgere “to fasten”; see fix

Explanation

In linguistics, the suffix is part of the word that's added onto the end, like the -ish in foolish. When a suffix is added to a word, it changes the form, like when adding the suffix -y turns the noun soap into the adjective soapy. You can also use suffix as a verb. If you suffix the word cake with -less, you end up cakeless, which is pretty sad, especially if it's your birthday.
