A chum of mine, who is a high school teacher, wrote to me and used the acronym LELL as if I would know what it meant. I didn't. In response to my inquiry, he said it means a Limited English Language Learner. I then asked where that phrase arose and he did not know. It sounds like one of those phrases that originates in legislation and is then shortened by those who have to use it, because it is in the law, repeatedly. But does anybody know?
