How do you know it's not SQL-lite with the single L serving a double role?

Common pronunciations allow you to stay perfectly ambiguous about where the L goes, which aligns quite well with the name as spelled. If you do it right, nobody can tell if you're saying sequel-ite or sequel-lite or seque-lite on the one hand, or S-Q-L-ite or S-Q-L-lite or S-Q-lite on the other.

AFAIK there is no official word on how the name is intended to be read or said.
