Hi Nat, it's confusing. "bita3 / bita3et + possessive suffix" means belongs to + pronoun. "bi" + verb in present tense indicates repeatable or continues taking action. If you mean "biyta3ib" then it means it makes someone tired. It's always better to put the word in a sentence to get the right explanation according to the context. Good luck!

bita3ib بتعب = متعب = tedious = tiresome This makes sense because it has been explained why, by "la2ano" which means "because" ;)

بتحب بلغة الشات

Bita3ib means it make you tired (both physically and morally)

Honestly this is unclear. At least as an Egyptian. If there was a typo for example and it is "bita3it" then it means belongs to (in the Egyptian dialect). Or "biy3atib" means to scold.
