Well, it's a little bit like the Shikaku thing I said.
"Shi" means "Four." "Kaku" means angle.
Therefore, "Shikaku", Four Angles = Square.

However, "Shi" also means "Die/Death". It depends on the Kanji or ideogram - Four is written differently from Death even though they sound equal.

Japanese _is_ hard to learn, but it's fun... the problem is spoken japanese (man they are fast!&#33 and the different accents. For instance, Naruto always uses a "te wa yo!!" at the end of almost every sentence. It gives the idea that he's not talking very respectuosly towards anyone. But it makes it hard to be understood.
