To tell someone to do an action faster using a short imperative sentence, we use “faster,” for example: Swim faster! Run faster! Walk faster! Climb faster! Crawl faster! Fly faster! Go faster! Move faster! Jump faster! So, to tell someone to slow down, we often use the general command “Slow down!” for all situations. But if I want to be more specific about the action, can I use “slowly”? Does it sound natural? For example: Swim slowly! Run slowly! Walk slowly! Climb slowly! Crawl slowly! Fly slowly! Go slowly! Move slowly! Jump slowly!
