English Language Development AKA ESL, English as Second Language. It's a class usually for those people who just came to America, and speak English as their second language. They used ESL before, but now, they all use ELD instead of ESL.
A: Are you still in ELD?
B: nope, I got out of that class last year.
( El’ – De) 1. Noun; abbreviation for the Cadillac El Dorado, commonly thought of as the “top of the line” in the Cadillac catalog. 2. Adjective; describing an upgraded or “top of the line” product or person. Used in context to give value to a particular item or person. Common misconception: El D or “L-D” does not refer to any particular part of the male anatomy and should not be interpreted as “large dick”, “loving dong” or any other bastardization of the term.
“So Jill, are you ready to step up to the El D, or are you happy with that shitty boyfriend you have?”
