Correct spelling

flexible

Correct spelling, explanation: the word flexible is made by adding the suffix -ible (meaning: to be possible), to the base word flex. You may know that the suffix -ible and -able mean the same thing, and wonder why flexible uses one over the other. There are two rules here: -ible is used when there is no full base word (like edible), and in certain words of Latin origin only – which is why we use it in flexible.

Definition of flexible:
adjective
1. elastic, possible to bend

2. possible to change or adjust

Incorrect spelling

flexable

Incorrect spelling, explanation: there may be some confusion around when to use the suffix -able and when to use -ible. They look similar, and mean the same thing, so why is flexable an incorrect word and flexible correct? In general, we mostly use -able to create new words and it’s quite versatile. On the other hand, -ible is used only in certain words of Latin origin (like flex), and in the case of words that don’t have a clear base word.
