köken: From Proto-Finnic *kirstu (compare Estonian kirst, Votic kirstu), of unknown further origin, but related to Latvian šķirsts (“chest, coffin”) and dialectal Russian ке́рста (kérsta); there is no consensus on the direction of borrowing. The word however cannot be older than Finnic due to the consonant cluster.
köken: Borrowed from Polish kufer or Ukrainian куфер (kufer), from German Koffer, from Late Middle High German koffer, from Middle Dutch coffer, from Old French cofre, from Latin cophinus, from Ancient Greek κόφινος (kóphinos, “basket”).
köken: First attested in 1786. Back-formation from bőrönde, from bőr (“skin”) + -önde (a suffix created by the language reformers). The -e ending was interpreted as a possessive suffix or a diminutive suffix, so the word was shortened. Created during the Hungarian language reform, which took place in the 18th–19th centuries. For the suffix, compare bölcsőde.
