Why is "L" the angular momentum

I was wondering why is L used as the symbol for angular momentum?

### Pseudo Statistic

Because the scientist that discovered it was sick and tired of using Greek symbols and said, "Hmmm, a random letter... l. But l's taking, so we'll use L."
Atleast, that's what I think. :D

There's no (or at least i haven't heard/read of a) justification...Merely a convention.You could ask why we denote the coordinates by x,y,& z instead of d,h,& k... Sometimes there is,sometimes there isn't an explanation...

C'mon! It's so OBVIOUS! L, as in AnguLar momentum.
