teach (one) a lesson

To convince one to avoid some unwanted behavior in the future through the inflicting of some form of punishment or harm. Can be said of the harm or punishment itself, or the agent inflicting the harm or punishment. After the CEO was found guilty, he was forced to repay $150 million in damages and will spend the next 10 years in jail. If that doesn't teach him a lesson, I don't know what will. A: "The cat scratched Bobby this time when he pulled its tail again." B: "Well, that ought to teach him a lesson." Are you going to mess with my little brother again, or am I going to have to teach you a lesson?

teach (one's) grandmother (how) to suck eggs

To try to teach an older person who is wiser, more experienced, and more worldly than a young person may think. Why are you explaining basic typing to Ethel? Sure, she's 70, but she's been using a computer since before you were born—quit teaching your grandmother to suck eggs! These young hotshots come in and try to prove they know the ropes better than we do, like they're teaching their grandmothers how to suck eggs.

teach away

1. In patent law, to criticize, discredit, or discourage a particular combination introduced or established in a later invention or reference, so as to preclude the latter's validity. Reference A clearly states that the placement of the parts within the machine, as detailed and proposed by Reference B, would fundamentally alter the functionality of the machine in a dangerous manner. It is thus our opinion that Reference A teaches away.
2. To teach in a foreign country; to teach abroad. I decided to get my certificate to teach English as a foreign language and spend the next year teaching away.

teach an old dog new tricks

Change longstanding habits or ways, especially in an old person. For example, His grandmother avoids using the microwave oven-you can't teach an old dog new tricks.

By 1546 a version of it appeared in John Heywood's proverb collection.
