The Monday streak is now to 64. That’s a lot of Mondays in a row. I’m proud to keep that going.

I pulled out 10D Cheese-on-toast dish: RAREBIT. I hadn’t heard of rarebit. So I looked up the etymology, and I am not satisfied.

rarebit (n.)

1785, an absurd perversion of (Welsh) rabbit, as if from rare (adj.) + bit (n.).

So no help.

I don’t know if I fully understand the the theme of this puzzle. I mean I think I get it, but I don’t know if it’s as superficial as it seems, since I haven’t seen a theme clue.

17A Marine inhabitant that’s an animal, not a plant, despite what it’s called: SEA[C]UCUMBER.
27A Angry shout to a miscreant: WHY[Y]OULITTLE.
41A Sobriquet for Simón Bolívar: EL[L]IBERTADOR.
54A Observation satellite: EYE[I]NTHESKY.

So the theme is just that the the word that precedes the circled letter is the letter as a word?

Finished this one in 6:00.
