What does the MySQL function name 'ELT' stand for?

Question

I understand what the function 'ELT' does but what does it stand for? It doesn't state in the official documentation and I can't seem to find it anywhere else either.

Answer 1

It stands for "Eagle, lettuce and tomato," the least-successful sandwich ever made.

Seriously, I believe it's just an abbreviation of "element," as in, give me the nth element of the following list.
