The word لازم (lazim) is another essential Arabic dialect word. It means "must" or "has to". It's used in many (if not all) dialects, not just Levantine, and understood by everyone. It's also a very simple word to use since you don't have to worry about conjugating it. You just conjugate the verb that comes after it.
1. لازم تروح ع الجامعة (lazim trooh 'aljami'a) = you have to go to the university
2. لازم تفكّر في الموضوع قبل ما تاخذ قرار (lazim itfakkir filmowdoo' abl ma takhuth araar) = you have to think about the issue before you make a decision
3. بكرا هو لازم يشتغل (bukra huwi lazim yashtagil) = tomorrow he has to work
