'Karczew (town in central Poland)'

ETYMOLOGY

Beider suggests that the name was borrowed from Old Polish, before the 16th c., when the first vowel of Karczew was long /aː/ (perhaps the vowel was lengthened in a stressed syllable before /r/ and a second consonant). The vowel merged with A₂ and had the corresponding different realizations in Yiddish dialects (e.g., "Kūrtshev" in CY).
