Answer:
The proper ending for "predict" is "able" --> predictable.
Step-by-step 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:
- If you know nature well enough, the weather becomes predictable to you.
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.
