Swim slow/slowly/more slowly/slower!

[kimconu]

To tell someone to do an action faster using a short imperative sentence, we use “faster” Swim faster!, Run faster!, Walk 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, , suppose Tom is doing something (swimming, running, etc.) too fast, and I want to urge or tell him to slow down. Which expression should I use? Does it sound natural?

- Hey Tom! Swim slow / slowly / more slowly / slower!
- Hey Tom! Run slow / slowly / more slowly / slower!
- Hey Tom! Walk slow / slowly / more slowly / slower!

As a learner, don't try to start sentences with "so".

But However, what should I say if I want to be more specific about the action?

As a learner, don't start sentences with "but".

Suppose Tom is doing something (swimming, running, etc.) too fast, and I want to urge or tell him to slow down. Which of the following expressions should I use? Does it Which sound natural?

- Hey, Tom! Swim slow/slowly/more slowly/slower!
- Hey, Tom! Run slow/slowly/more slowly/slower!
- Hey, Tom! Walk slow/slowly/more slowly/slower!

Note my corrections above. We don't put a space on either side of a slash.

Regardless of the verb, you can use only "more slowly" or "slower" if you mean "less fast". Using "slow" or "slowly" means you're dictating that he goes specifically at a slow rate, rather than indicating that you think his current speed is too fast.

For info, I'd probably say "Tom, don't swim so fast".
