What it means
てください attaches to the て-form of a verb to make a polite request. It means “Please do...” and is commonly used when asking someone to perform an action. The request is polite but direct, so it is suitable for everyday situations and clear instructions.
Usage note
てください is polite, but it is not the most formal request. For especially respectful situations, use a more indirect form such as ていただけますか. The familiar counterpart てくれ is much more forceful and should generally be limited to close relationships or situations where the speaker has authority.
