Answer 1

Rule C - Group III: The suffix “-able” always follows “i”.

Step-by-step explanation

When a word ends in “y”, such as “envy”, the “y” becomes an “i” when adding the suffix“-able” to make new adjectives. In this case, envy becomes enviable. There are other examples which exemplify this rule: justify - justifiable, or rely - reliable.

Answer 2

The given root word above is the word "envy" and the rule that applies to this word is option C. Group III. The suffix -able always follows i. With the word envy, the last letter "y" should be changed to "i" then add a vowel suffix. In Group III, as stated, we change the "y" to "i" then add -able, so the word becomes "enviable" making it an adjective. Hope this helps!
