Learn English – Is the phrase “come fast” a grammatically correct imperative?


Is the following sentence grammatically correct as a command?

"Come fast."

I believe this would be a correct alternative:

"Come quick."

It depends on what was intended. To invite people to participate in a religious practice of not eating, “come fast” works but “come quick” doesn’t.

Grammar that doesn’t consider intent is a low bar to cross. If a sentence conveys meaning in some context - any context - it’s grammatical. And some would say that’s already too high a standard for grammaticality.
