JLPT N5 · Grammar
Highlighted parts are the fixed pieces of the pattern; the rest changes with the word you attach it to.
## What it means This pattern means "please don't ~". It's a polite way to ask someone not to do something.
## When to use it Take the **nai-form** of a verb, then add でください. So 吸う ("to smoke") becomes 吸わない, and then 吸わないでください means "please don't smoke". It works the same way for any verb — build the nai-form first, then attach でください.
## Don't confuse it with This is the direct opposite of **〜てください** ("please do ~"), which uses the て-form instead of the nai-form. たべてください means "please eat", while たべないでください means "please don't eat" — the only difference is which form of the verb you use, so it's easy to mix them up if you're not paying attention to the verb ending.
