What is the Egyptian word for warrior?

I guess you mean the ancient Egyptian Word, not the modern Arabic one.

We know how ancient Egyptian Words were written, but not how they were said since vowels were not included in hieroglyphs. There is more than one Word with that meaning:

kfaw [where a is a consonant sound that does not exist in English] - a warrior

thr a Syrian warrior

aHAwty a warrior

mryn a Syrian warrior
