What ending should this word have? predict- able ible

The proper ending for "predict" is "able" --> predictable.

Explanation:

The suffixes -able and -ible are of similar use and meaning. Adding them to the end of a word means the thing or person we refer to is "capable of being" that word. For instance:

The weather, in the sentence above, is "capable of being predicted".

Usually, we add -able to full words: enjoy - enjoyable; rely - reliable. We add -ible to words that are not complete and cannot be used on their own: poss - possible; ed - edible.

just took the test;

argument: "it's time to wage a war against britain to secure american freedom."

claims: "america has tried every peaceful method available for seperating from england" & "the americans' petitions to the king have been turned away by him."

i literally just read the book and studied it for months so i could you, but i need to know where these questions are coming from. they are too general.
