Body Language: Part 2

(Update to this post)

I consulted a friend who told me that it was more likely that his tattoo said "echad" and means "one." One is written as אחד in Hebrew. I am not sure as to the full accuracy of any of this due to my lack of experience with Hebrew. According to my friend:

Echad can mean unity, but there's also more than one word for it, and Echat ¹ is, literally, one.

And further, he added in response to me saying that I was pretty confident in our discussions of what I saw:

Then it was Echad, which, is a rather stupid tattoo.

Note ¹: This was a relatively informal discussion and spellings were inconsistent at times, but I'm sure it's all on the level.
