köken: First mentioned in 1915, alongside the less common variant cenceñada (“hearfrost”). A theory points at a back-formation from earlier *recencellada (“hearfrost”) (1894, only found in Luis Maldonado), from recencio (“a north-west wind; hearfrost”), either from cierzo (“a north-west wind”) or from Latin recēns (“fresh”), or, according to RAE, directly from cierzo (“a north-west wind”).
köken: Borrowed from English rime, from Middle English rim, rime, rym, ryme (“hoar frost; rime”), from Old English hrīm (“frost”), from Proto-West Germanic *hrīm (“rime; hoar frost”), from Proto-Germanic *hrīmą (North Germanic), *hrīmaz, *hrīmô, probably from Proto-Indo-European *krey- (“to graze, touch; to streak”).
köken: Inherited from Proto-Slavic *seržь (expected would be **среж), possibly merged with *skręga (“curtailment”) (whence Russian скря́га (skrjága, “cheapskate”)).
