Word of the Day: GOLEM (119A: Monster of Jewish folklore) —
In Jewish folklore, a golem [...] is an animated anthropomorphic being, created entirely from inanimate matter. The word was used to mean an amorphous, unformed material in Psalms and medieval writing. // The most famous golem narrative involves Judah Loew ben Bezalel, the late 16th century chief rabbi of Prague. // The word golem occurs once in the Bible in Psalm 139:16, which uses the word גלמי, meaning "my unshaped form". The Mishnah uses the term for an uncultivated person: "Seven characteristics are in an uncultivated person, and seven in a learned one", Pirkei Avos 5:9 in the Hebrew text (English translations vary). In modern Hebrew golem is used to mean "dumb" or "helpless". Similarly, its is often used today as a metaphor for a brainless lunk or entity who serves man under controlled conditions but is hostile to him and others. "Golem" passed into Yiddish as goylem to mean someone who is clumsy or slow. (wikipedia)

Reader wrote me ahead of time and told me this was probably the easiest Sunday puzzle she'd ever done, so I was expecting some kind of record time, but I wasn't even close. It's reasonably easy, but I

Just a few hang-ups today, most notably in the SW, where LONG FOR really made a mess of things for a while. Took a while before I had the good sense to change it to ACHE FOR (89A: Desperately want). I thought TOM was the [Pal of Huck Finn] (JIM) and thought the [Injury symptom] was a

Bullets:
- 13A: Crosswise to the keel (ABEAM) — like ABAFT, I learned this from xwords.
- 22A: Onetime first name in Israeli politics (GOLDA) — had this been four letters, I'd have been lost, but at five, GOLDA was the first name to come to mind.
- 79A: Handbag monogram (YSL) — one of the few fashion monogram's I'm aware of (besides, perhaps, DKNY).
- 86A: Reed of rock (LOU) — wanted OBOE (no, not really)
- 87A: "1984" superstate (EURASIA) — somehow, this never seems fictional enough to be from "1984"; but there it is.
- 2D: Jimi Hendrix's debut single ("HEY JOE") — already one of the most searched for terms of the day—I apparently covered it in a bygone write-up.
- 8A: "___ hath an enemy called ignorance": Ben Jonson ("ART") — I teach Jonson every year but didn't know this. One of two literary quotes today, the other coming from Harriet Beecher STOWE (29D: Best-selling author who wrote "I did not write it. God wrote it. I merely did his dictation").
- 13D: Swirly marbles (AGATES) — considered AGGIES for a bit. That's slang for AGATES, right? I've never played marbles, so what do I know?
