Here was the best explanation I found in the Toot link above: @rothko@beige.party … it’s not a riddle. each phrase is merely a statement of fact.

“What” is a word made up of 4 letters.

“Yet” is made up of 3.

“Although” is written with 8 letters"

and “then” with 4.

“Rarely” consists of 6, and

“never” is written with 5.

it’s not actually asking for an answer

Is this loss?

The second full-stop breaks the connection to the word “letters” needed in the last sentence.

Yes

Classic … >!It’s a statement not a question!<

My brain was trying to make various synonyms for “shit” work 😅
