What’s the difference between portend and presage?
Do they have any differences with each other?
There is really no difference in the meaning of the 2 words as verbs. They both mean to warn of something to come in the future, usually something unpleasant.
It’s worth noting that presage can also be a noun, meaning an omen or warning. Portend is only a verb, but we have the noun portent which is derived from the same Latin root.
