Hi 17th
Oh my goodness I just looked up the Kurdish numbers, the words are so different to Arabic, so can't help you with that one.
Don't worry too much about insulting people, Arabs are very friendly people and will just be delighted that you are making an attempt to communicate in their language.
I believe Kurdish is closely linked to Farsi and I have a good friend that I speak to online every day that is Iranian, therefore a native Farsi speaker, so if that can help in any way just shout up.
Oh aren't languages brilliant I just searched for Kurdish language phrasebooks and came across a language comparison - it seems that the word for woman in Kurdish is the arabic word for demon and in Russian the word for wife is the arabic word for adultery.
