Puzzle Ninety-Four: The Limits of My Language (18x15 themeless)

My wife challenged me to construct a puzzle with 40-Across as a seed entry. 2 years later, it's here.

Apologies for the lack of a January contest meta, and for the delay in posting answers for Thanks I Hate It from October and the Super Secret Contest Meta, whose deadline was December 31. I have been dealing with a whole lot since December and where I have a number of non-meta puzzles already in the queue, I haven't had the mental energy to create a contest meta in a couple of months. I hope to bring it back, but for now the meta contest has to go on hiatus. 

I have a Universal puzzle set to run on February 18. I posted a few new PuzzGrids (Connections / Only Connect-style puzzles) this fall. And if you're a National Puzzle League member, I debuted as a contributor to The Enigma last issue with two flats.
