Ten abbreviations for texting in English:
1• hru - how are you

?
2• wyd - what are you doing?
3• wbu/hbu - what about you?/how about you?
4• ur - your
5• ty/tysm - thank you/thank you so much
6• wht - what
7• y - why
8• bc - because
9• lol - (to express) laugh out loud
10• idk - i dont know

I hope this is useful :) I sometimes forget that I am talking to some foreigners that dont know shorthand in texting. Let me know if i should do more of this to help you guys or ask me any questions
