Pronunciation

Forms

ле́то (léto) n inan (genitive ле́та, nominative plural лета́, genitive plural лет, relational adjective ле́тний or ле́тный)[1] Before 1918 it was spelt лѣто, as in „Писано в обозѣ под Азовом лѣта 1695” “written in the camp before Azov in the year 1695”.[2][1] The genitive plural лет serves as the genitive plural of год after numerals: пять лет “five years”.[3][4]

Etymology

It is inherited from Old East Slavic лѣто (lěto, “time; year; summer”), from Proto-Slavic *lěto (“summer; year”).[1][3][5] The word is common Slavic: Old Church Slavonic лѣто (lěto) renders Ancient Greek χρόνος (khrónos) and ἔτος (étos), and there are Ukrainian літо (lito), Bulgarian лято (ljato), Czech léto, Polish lato and Upper Sorbian lěto (“year”).[6][3]

Its origin is unclear, and no etymology is generally accepted.[3][7] The main views:[7]

  • Vasmer thinks it possibly related to the Swedish dialect word låding (“spring”) and to Old Irish laithe (“day”), which would make it a Celtic–Slavic word;[6] Björkman and Ahlqvist, however, suspected the Scandinavian words of coming from Middle English.[6] Chernykh takes only the Irish word as a sure cognate and starts from a base meaning “the time when the sun shines and warms”.[3]
  • Vaillant derived it from the root of Lithuanian lėtas (“soft, quiet, slow”) and Latvian lēts (“light”), meaning “to slacken”, so that the word first meant “the mild time, when the cold relents”;[7] Sławski thought this the most likely, and Anikin developed it.[7] Shaposhnikov, Shansky and Bobrova follow it.[8][9]
  • Others connected it with лить “to pour” and Lithuanian lietus (“rain”), as “the time of rains”.[6][10]
  • Machek took the word to be an adjective “fine”, agreeing with an understood *vermę (“time”), and related to Latin laetus (“glad”).[6]

Vasmer rejects a loan from Old Irish líth (“feast”) and calls a link with волна pure guesswork.[6] Wiktionary reconstructs Proto-Indo-European *leh₁tóm (“warm part of the year”).[1]

Earliest recorded meaning

Miklosich cites the Ostromir Gospel of 1056–1057 for лѣто in the sense “time”, Greek χρόνος.[11] Chernykh dates the Old Russian word from the 11th century in the senses “time in general”, “year” and “summer”.[3] The Novgorod Menaion for November of 1097 has „въ послѣдьняя лѣта” “in the last times”.[12]

Semantic evolution

In Old Russian the word was above all the “year” of dates, as in „въ лѣто 6576” “in the year 6576” on the Tmutarakan stone of 1068;[13] Shansky and Bobrova link the counting of years by summers with летопись “chronicle”.[9] The Lay of Igor's Campaign has „минула лѣта Ярославля” “the years of Yaroslav are gone”.[12] The 18th century still used it mainly for “year”, with phrases such as многая лѣта “many years”, a wish for long life.[2]

In modern Russian it means “summer”; the plural лета “years, age” is dated or poetic.[4] In Olonets лето also means “south”, and летний ветер a south wind;[6] Shansky and Bobrova explain this from the warm weather.[9]
