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: From Proto-Finnic *härmä (compare Estonian härm, Karelian härmä, Livonian ǟrma; from earlier *šärmä), borrowed from Proto-Baltic [Term?] (compare Latvian sarma, Lithuanian šarma).
köken: Inherited from Proto-Slavic *seržь (expected would be **среж), possibly merged with *skręga (“curtailment”) (whence Russian скря́га (skrjága, “cheapskate”)).
