The book asks me to make new verbs from the following words: clear, noble, body, rate, store.
For clear, I can use clarify; for body, embody; for store, restore.
For noble, I am not able to think of any new verb. For rate, ratify doesn't just satisfy me because I guess the meaning of rate and ratify are different, unlikely from clear and clarify which still have the same kind of meaning.
I wish somebody could help me with noble and rate.
