You can pronounce Itai however you like (if you pronounce it 'asshole' that would be rude unless it's appropriate given the situation) however technically you are supposed to pronounce it ee-tai (like the letter E and then the ti in time)
It is spelled איתי in Hebrew
א is the first letter of the alphabet, ת is the last, and י is the tenth, the numerical value is 421
It means 'friend' or 'with me' in Hebrew
Because it was a name given to a general who was originally named something else, it is often a name that people change their names to
It means pain in Japanese, which wasn't intentional but works really well
