Questions & Answers about كان لازم اغير اللمبة لانه ما كان في ضو بالغرفة.

Why does the sentence start with كان لازم? Why not just لازم?

In Levantine, لازم means must / have to / necessary. Very often, speakers add كان before it to put the obligation in the past:

• لازم اغير اللمبة = I have to change the bulb
• كان لازم اغير اللمبة = I had to change the bulb / I needed to change the bulb

So كان here shifts the idea into the past.

What does اغير mean exactly, and what form is it?

اغير means I change or, in context, I change/replace.

It comes from the verb غيّر = to change.
This is the first person singular imperfect form:

• بغيّر = I change / I am changing in everyday present
• اغير = often used after things like لازم, بدي, ممكن, etc.

So after لازم, Levantine commonly uses this form without بـ:

• لازم اغير = I have to change
• not usually لازم بغيّر

Why is it اللمبة and not another word for light bulb?
