Other forms: suffixes; suffixed; suffixing

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.
