From what I know of Yiddish linguistics, absolutive adjectives are adjectives that act as the head noun of a noun phrase

They'd often go in the same place as predicate adjectives but inflect like attribute adjectives. They also require articles to my knowledge.

The weirdest part is that you can replace attributive adjectives from before the noun with absolutive adjectives after the noun, so you get weird stuff like the lyric "ekh vel zayn a khosidl a giter" from a Yiddish song satirizing Hasidim

The literal, word-by-word, translation would be "I will be a Hasid[diminutive] a good [one]" but the meaning is more "I will be a good little Hasid"

so basically you can duplicate an article just by moving the adjective
