～てくれるTo do something for someone (usually you)

The verb 呉(く)れる in Japanese, is very similar to 与(あた)える (to bestow). The primary difference is that 呉(く)れる (primarily written in hiragana) means to 'bestow to the speaker' (or someone in the speakers inner circle).

In this way, てくれる is the opposite of てあげる, which conveys that someone (usually the speaker) gives (an action) to another person that is outside of their inner circle. てくれる is commonly translated as 'would you do (A) for me', as a question, or 'someone did (A) for me', as a statement.

When asking for a favor, てくれる can be shortened to てくれ. However, this is very casual, and should not be used with strangers (or anyone that you do not know well). As an English equivalent, てくれ sounds similar to phrases like 'would ya do (A)', or 'could ya do (A)?'

Fun Fact

てくれる is one of the most casual ways to ask for a favor, with てもらう being slightly more polite. ていただく (the humble speech variation of てくれる) is even more polite than either of these!
