This is a standard PSE connect wall in that you must find four groups of four.
Then find the commonality between those four groups (not a word that fits into all four groups, as some connect walls require). The title refers to that commonality.
This is my first connect wall, so I got a couple rounds of feedback from a knowledgeable friend and altered this puzzle accordingly.
- This wall contains a few US-centric terms, so it might be easier for Americans.
- No words need to be flipped (reversed).
- Here are the word frequencies for the past 100 years for some of the rarer words in the grid. (Clarification: These frequencies are for the words as they relate to the connection, not the word from the image. This is a good hint within itself.)
EDIT: Sept 9, 2022:
Added in word lengths to each of the 16 images.
Added A1Z26 checksums per row (top to bottom): 117, 130, 204, 205
Added clarification under the frequencies bullet point above.
