Yes, they do.
IMO in German = mMn (meiner Meinung nach)
But for the most part we use the English ones
zB = zum Beispiel = for example
usw = und so weiter = and so forth
etc = etcetera = and so forth
we love shortings too
smh = iwie (irgendwie)
How r u = wg (wie geht’s)
somebody = jmd (jemand)
Shut up = hdf (Halt die Fresse)
probs = wsl (wahrscheinlich)
idk = kp (kein Plan)
kp could also be “kein Problem” (no problem) which is why I personally prefer idk / np over kp / kp
I’m using none of these. But what i use almost all the time : possibly = evtl (eventuell) maybe = vllt (vielleicht) kindest regards = LG (Liebe Grüße) e.g. /for example = zB (z.B.: / zum Beispiel) (i omit the dots and colons)
One of my favorites is in Japanese. Laughing is “w” or “www” or something. The word is “warau”. So then the ws, they look like grass, so people use the grass emoji, so then people write “kusa”.
In Portuguese we don’t use many acronyms, but we have shorter versions of words with the vowels removed or things like that. When people tried to use acronyms we ended up with “fds” which some people read as weekend, others read as “fuck it”. The only other acronyms I can think of right now are all for offenses such as fdp (son of a bitch) and cdf (“ass of iron”, very old term for calling someone a nerd).
The only Hindi acronyms that I know of are offensive. There’s mc, which stands for madarchod (motherfucker), and bc, which stands for behenchod (sister fucker).
There’s also the rarely used AMJ, Hindi equivalent of TIL, used on the Hindi version of r/todayilearnt (r/aajmainejana).
