Etymology

Origin of afternoon

Middle English word dating back to 1250–1300; see origin at after, noon

Explanation

The afternoon is the time of day that starts mid-day and ends in the evening. If you have an afternoon appointment, it's probably some time between 12:00 and 5:00 p.m. It's pretty much agreed that the afternoon begins after noon, or 12:00 p.m., but when the afternoon ends and evening begins is a bit more vague. Still, if you ask a friend to meet you for coffee in the afternoon, she will know what you mean. You can even use the word afternoon as a casual greeting, short for "Good afternoon!" In Middle English, the word was aftermete, meaning "after the noon meal."
