In a crisp manner; sharply, clearly, or in a way that is firm and snappy.
From 'crisp' (adjective) plus adverb suffix '-ly.' This is the most common adverbial form, used since Middle English to describe both sounds and manner of speaking.
When someone speaks 'crisply,' they're using a word that originally described curled hair but now describes sharp, clean communication—a beautiful example of how metaphors expand across meanings.
