Beginner - I'm thirsty

Ahlan!
A small question on grammar.
I thought this was the conjugation of sh-r-b (to drink)

ana ashrab
ant/ hiya tashrab
anti tashribi
huwa yashrab

so why does the speaker in the dialogue say
'tishrab a9ir?' Why the I after the T. Isn't it tashrab? I know you said it's colloquial. But is there a specific logic regarding where to make this adjustment? Can you give any other examples of this difference in colloquial and classical in conjugation of the imperfect tense?
Shokran

I can give you more examples, like te3mal (to work) and teshtary (to buy)... but there is no rule for it, so it is better to focus on the classical ones if you prefer rules and grammars.
We teach some colloquial for those who live in Arab countries and they want to communicate easily with their colleagues and friends,, we are trying the best to satisfy most of you here :).

to abhikek :

you are right the correct ( tashrab )

and there is question mark deleted which it

( hal )

and the correct sentence is

hal tashrabu 3a9eeran ? not :

Teshrab 3a9eer?

and note :

anti tashrabin not tashrabi

Hi Ehab,

I think you guys are doing a great job. It is good to have a mix of colloquial and MSA. After all if you are travelling it is colloquial is what people will be using in their daily lives. Anyway I like the fact we get exposure to this.

Cheers :-)

Hey guys,

Just curious what the beginning (and ending) song on every lesson is talking about. I hear "allah" but don't understand anything else.
