köken: From Old Swedish aptan, aftan, afton, from Old Norse aptann, from Proto-Germanic *ēbanþs, from Proto-Indo-European *h₁epi. Cognates include Norwegian Nynorsk aftan, Norwegian Bokmål aften, Danish aften, Icelandic aftann, English even (evening), Dutch avond and German Abend.
eve (day or night before, usually used for holidays)
çekim: çoğul aatot · tamlayan aaton
köken: Borrowed from Old Swedish apton, afton (“evening, eve”); “evening” and “eve” are the same word in Swedish because the ecclesiastical day changes at 6 p.m., but only the sense “eve” has been borrowed into Finnish.
fast, fasting (abstaining from or eating very little food) · the day before a holiday when people fast, or in general the day before any event; eve
çekim: çoğul ajunuri · tamlayan ajunului
köken: Probably from Latin iēiūnium or iēiūnus through a Vulgar Latin root *iaiūnus > *aiūnus, from Proto-Italic *jagjūnos, itself from Proto-Indo-European *Hyeh₂ǵ-yu-, adjectival form of *Hyeh₂ǵ-ye/o- (“to sacrifice”). Compare Spanish ayuno, French jeun, jeûne, also Italian digiuno. The equivalent Aromanian word agiun also carries the sense of 'starving', 'hungry'.
