مسعاك*

بوركتي يا بنية وبورك مساعك

Good Abdullah:) وبارك الله فيك.

hhhhhhhhhh ok I got it and from today just speak formal language with them even not informal

Abdullah, this is a joke right?;) The way foreigners speak Arabic is not a language to be corrected. But you can do something about it; when ever you speak to one of our foreigner brothers & sisters, try to speak to him/her in the right Arabic language, this way they'll pick up the real Arabic words faster. I think it's our responsibility to teach them using the right words:) After all they only repeat the words we use with them.
