I was doing a crossword from the NY Times (from Tuesday, October 25, 2022 By Ashleigh Silveira, Nick Shephard / Will Shortz) and I got the following clue.
29 DOWN - Loss leader?
The answer is "ELL". However, I do not understand why and how "ELL" fits the clue.
Why is the answer "ELL" and how does the clue fit?
