Sizable or Sizeable: What’s the Difference?

Suffixes in English can be confusing. A suffix is a modifier attached to the end of a word. Suffixes can change the meaning of a word and even allow it to be used as different parts of speech.

One common suffix, -able, changes a verb into an adjective. Something which can be fixed is fixable, for instance; someone who is easy to get along with might be described as relatable.

This suffix isn’t always so straightforward, though. What happens when a word ends in -e, like size? When we add -able, should the E be omitted, or retained? Is the correct word sizeable, or sizable?
