Actually, Paul, I mistyped.

I meant to write that just because "sideco" is listed in a Yoruba dictionary, it doesn't mean it originally comes from that language.

As to the origin of the word juju-I always thought that it came from Yoruba or some other African language. But I've no proof of that.

Of course, words with the same or similar spelling and the same or similar pronuciation can be in more than one language and have entirely different origins & meanings.
