I saw somebody with a hebrew tattoo on the train today. It was only three letters, and I believe they were (from right to left) Kof, Zayin, Chet. Is this a word? It might have been a Nun at the front, I couldn't really make it out perfectly, and I felt that more prolonged staring would cause problems.
Huge amounts of respect and thanks to anyone who can help me out with this one.
