قوي و جداً

قوي means strong or powerful

جدا means very

ther's no similarity between them for example:

that man is very strong>> الراجل ده قوي جدا

he is very tall>>هو طويل جدا

ps:اوي has the samemeaning of جدا

So would you say طعبان جداً  or طعبان قوي?

Hello, about your last sentence, it could be : تعبان جدا / I am too tired.

Regards.

We don't say قوي in dialect, we say it اوي in Egypt. You can say تعبان جدا او تعبان اوي.

I guess you know that we spell the ق as if it's أ

We use both of them to express the same meaning. 

تعبان قوي = تعبان جدًا = تعبان على الآخر = تعبان خالص = تعبان موت 

All are Egyptian slang

It's same meanz, both meaning " too much "

Thanks for the feedback :-)

Oh and yes, I understand that قوي is pronounced as اوي.  The books I've been using/reading include the ق in spelling, but also says that it is silenced. 

Thanks again.
