same here, but only when it feels like good conversation or is a subject we already discuss. Especially if youre in the same room, then it can become a little trivia game and if no one knows then someone can look it up

related note, my girlfriend is bilingual with spanish, and i only have some old high school classes of spanish to go off of, so whenever she texts me a word i dont recognize i ask her what it means. Aside from helping me understand, she gets a peek into my literacy level (which is admittedly pretty low), i can call out the word when its used again, and i get the impression she likes teaching me these little things.

extending the lesson beyond our little ritual, when you ask another person for the information it goes beyond being useful to each other. it is a bid for connection, and a display that you trust them and their opinion/knowledge on the subject.
