κιρρός

Ancient Greek

Unexplained, with the same geminate -ρρ- as in πυρρός (purrhós, “red”). The traditional derivation by Pokorny from Proto-Indo-European *(s)ḱeh₃- (“shadow, darkness”)^[1] and comparisons with Proto-Slavic *śěrъ (“grey”) and Irish ciar (“dark”) are phonetically problematic, as is the link to Lithuanian širmas (“grey”), since Lithuanian -ir- is from a zero-grade.^[2]
