Grammar hook - irregular plurals of body parts

Body parts are where Russian plurals go rogue. Ухо (ear) becomes уши - not *ухи or *уха. Глаз (eye) becomes глаза with a stress shift. Рука (hand/arm) pluralizes normally to руки, but its genitive plural is just рук - a bare stem with zero ending.

These aren't exceptions - they're suppletive and irregular forms inherited from Old Russian. The oldest, most frequently used words in any language resist regularization. Body parts, used daily for millennia, are exactly those words.

Body parts in context

У меня болит голова.
U menya bolit golova.
I have a headache. (Lit: My head hurts.)
болит + nominative - the body part is the grammatical subject
У неё красивые глаза.
U neyo krasivye glaza.
She has beautiful eyes.
глаз → глаза (irregular plural); кра­сивые (pl.) agrees
Врач сказал открыть рот.
Vrach skazal otkryt' rot.
The doctor said to open my mouth.
рот (acc. = nom. for inanimate masc.) - but gen. is рта (fleeting vowel)
Я сломал палец на ноге.
Ya slomal palets na noge.
I broke my toe. (Lit: finger on my leg.)
палец на ноге = toe; палец на руке = finger - Russian doesn't distinguish
Cultural context

"У меня болит..." is survival vocabulary. At any Russian clinic or hospital, you describe pain with this construction: У меня болит + the body part in nominative. Болит (singular) for one thing, болят (plural) for multiple. Knowing this pattern is more useful than any medical dictionary.

Рука means both hand and arm. Russian doesn't distinguish between them - рука covers everything from shoulder to fingertips. Same with нога (leg + foot). To be specific, you add qualifiers: кисть руки (hand, literally "wrist of the arm") or стопа (foot).

Язык has a double life. Язык means both "tongue" (the body part) and "language." "Русский язык" is "the Russian language," but "покажите язык" means "stick out your tongue." Context always makes it clear.
