Group II. The group is a full root word except for a final e. Is what i'm thinking. Sorry I'm unsure.

Answer 2

Answer:

The rule that applies to the word desire is Group II. When the root is a full word except for a final e, the forms usually are spelled with -able.

Explanation:

Suffix -able is used to turn verbs into adjectives and means that something can be done or that is capable of something. There are many spelling rules used to introduce the suffix -able; the one that applies to the word desire is Group II, since it turns the word desire into desirable.
