Almost every NYT puzzle introduces new answer words to the puzzleverse. This page collects answer words debuted by a single constructor.
Words in this color debuted by this constructor in the Shortz Era but did appear in earlier pre-Shortz puzzles.
Even better, the table below also shows reused words — answers debuted by David J. W. Simpson that have since appeared in later crosswords. These are often particularly interesting. After all, someone else found them clever or useful enough to steal. I mean, recycle.
