I'll do it for you

An old-fashioned ending in which the speaker promises or pledges to do something, normally to someone younger and often with a swagger: I will treat you to a good meal, I will show you what I have got, I will teach you a lesson. Modern speech keeps it mainly for that theatrical effect, and it can be either kindly or threatening depending on the verb. Two lines here are false matches where the syllable belongs to another word.

Register: old-fashioned; downward, kindly or boastful
