The difference

From my research, the suffix –able is still being used to make new adjectives but the suffix –ible is not.

This means adjectives ending with the suffix -ible are older words that were made in the past.

This is also why we hear words ending with ABLE more often than words ending with IBLE. New words with the suffix -able are still being made!

The suffixes “-able” and “-ible” are both used to form adjectives meaning “possible, capable of, suitable for, or causing.” Of the two, “-able” is much more common: it is what’s known as a “living” or “productive” suffix, meaning that it is still being used to create new words. The variant “-ible,” on the other hand, is only used in older words that have survived into modern English.

Can the suffix -able be used with any word?

No, the suffix -able cannot be used with any word in English. The suffix -able is used with verbs and nouns to make new adjectives. Native speakers add -able to the end of verbs quite often in informal situations to show that something is possible, but not every verb will accept this suffix.

Some more common verbs that don’t have an adjective made with the suffix -able are: 

• act
• come
• go
• meet
• say

Eat is another exception. The spelling changes to become the adjective edible.

Are there any rules for using the suffix -able in English?

The final “e” in the base verb is usually dropped before adding -able. for example BELIEVABLE. 

This doesn’t happen in cases where the “e” is part of a vowel-consonant-e (VCE) pattern, such as “loveable” (from “love”). O is a Vowel – V is a Consonant – followed by the letter E.

If the base verb ends in “y,” the “y” is usually changed to “i” before adding -able. For example, “reliable” (from “rely”). *An exception is enjoyable.
