A professor at a nearby university just scheduled an appointment with my daughter. He wrote, "I will meet you at 2 pm, NLT 2:15."
NLT? My daughter searched the college map to figure out which building was NLT or NLT 2. She asked me what else NLT might mean. I had no idea. It might be a building, a performance venue (since she was auditioning), or an abbreviation of another kind. It does not appear in my "Texting Dictionary of Acronyms."
Have you seen NLT before? Do you know what it stands for?
An online search revealed that the professor must have meant he would meet her no later than 2:15. Why didn't he say that?
