ah-SEHR BWEH-nah LEH-trah
Literally, this means 'to make good handwriting'.
In practice, it means to be on your best behavior to impress someone.
El nuevo empleado está haciendo buena letra para que le suban el sueldo.
B2The new employee is on his best behavior so they'll raise his salary.
Cuando voy a casa de mis suegros, siempre intento hacer buena letra.
B2When I go to my in-laws' house, I always try to be on my best behavior.
This expression comes straight from the classroom. In the past, having neat and beautiful handwriting ('buena letra') was a very important way for a student to impress the teacher. A student who tried hard to write well was seen as diligent and eager to please. Over time, the idea of 'making good handwriting' for a teacher expanded to mean doing anything to impress a person in authority.
Use this idiom when someone is clearly trying to impress a person in a position of power, like a boss, a teacher, or even a potential father-in-law. It often implies the behavior is a conscious effort to gain favor.
Mistake: “Confusing this idiom with the literal act of having good handwriting.”
Correction: This phrase is almost always used to talk about behavior. If you want to say someone actually has nice handwriting, you should say 'tiene buena letra' ('he/she has good handwriting').
Very common and widely understood in all contexts.
Understood in many countries, especially in the Southern Cone (Argentina, Chile, Uruguay), but other local expressions might be more common depending on the country.

It can. While it can be neutral (like trying to impress your in-laws), it often carries a slightly cynical tone, implying that the person's good behavior is calculated and not entirely genuine. It's not as strong or negative as the idiom 'hacer la pelota' (to suck up).
