Does it exist texting abbreviations in Spanish like in English?
You = u
Are = r
For = 4
Too = to
Be = b
See = c
Why = y
What would be those in Spanish?
We used a lot of abbreviations back in the times of the SMS. But now they're considered bad and uncomfortable, though they appear in jokes and memes. But in general you should 100% avoid them.
I don’t think a lot of those words listed really exist abbreviated in Spanish texting but here’s an article about Spanish texting; https://www.fluentu.com/blog/spanish/spanish-text-message-slang/
I personally like “@“ in place of “o/a”. It’s shorter and catchier to the eye. (I see sentences like “quiero amig@s para hablar en ingles” a lot on Duolingo).
There was a lot of use and abuse of them in SMS's, but they aren't so frequent in other texts. They vary in different countries and ages. Some known abbreviations are "x = por", "2 = -dos (kri2 = queridos)", "k = que", "tkm/tqm = te quiero mucho", "$ / $$$ = dinero, plata (no tengo $ / no tengo $$$)".
