TYVM

TYVM is widely used in casual texting, as a quick, polite way to express gratitude without typing the full phrase. TYVM is common in chats, forums, and social media posts when you want to acknowledge someone's help or respond to a compliment. Nowadays, Gen Z probably prefer to use emojis (🙏, ❤️) and most other generations might just say "thx" for speed, but TYVM is still out there, doing it's bit in a slightly more formal yet still friendly way.

Of course, as with most abbreviations, TYVM can be used sarcastically (i.e., to mean "Thanks for nothing"). You have to read the context to understand whether it is being used genuinely or sarcastically.

TYVM is an initialism, because it’s pronounced letter by letter — "T-Y-V-M." It's not an acronym, as they form pronounceable words (abbreviations like FANG, GOAT, NASA, NATO, ROWE, TACO, YOLO). In short: if you can say it like a word, it’s an acronym. If you have to spell it out, it's an initialism.
