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.
yesterday · tomorrow · any indefinite time in the past or future
çekim: çoğul कलों
köken: Inherited from Prakrit 𑀓𑀮𑁆𑀮𑀁 (kallaṃ, “tomorrow, yesterday”), from Sanskrit कल्यम् (kalyam, “at dawn, yesterday”), an adverbial accusative attested as early as the Mahabharata, from कल्य (kalya, “dawn”). Cognate with Marathi काल (kāl), Bengali কাল (kal), and Punjabi ਕੱਲ੍ਹ (kallh).
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'.
Inherited from Old Spanish viésperas (“evening, vespers, eve”), inherited from Latin vespera. For the lack of vowel syncope despite being an inherited word, compare áspero, níspero, miércoles. For the development of the stressed vowel, also compare avispa (from Old Spanish biespa).
