Etymology

It is inherited from Middle High German sumer, inherited from Old High German sumar, inherited from Proto-West Germanic *sumar, inherited from Proto-Germanic *sumaraz (“summer”).[2][1][3] The same word is Old Saxon sumar, Old Norse sumar, Old English sumor (now English summer), Old Frisian sumur and Dutch zomer.[2][4][5] It is unrecorded only in Gothic, where Wulfila rendered Ancient Greek θέρος (théros, “summer”) by Gothic 𐌰𐍃𐌰𐌽𐍃 (asans, “harvest”).[6]

Pfeifer and Duden trace it to Proto-Indo-European *sem- (“summer”), also found in Sanskrit समा (sámā, “half-year, season”), Avestan ham- (“summer”) and Old Irish sam (“summer”).[4][7] Kluge points out that only Old Armenian ամառն (amaṙn, “summer”), beside ամ (am, “year”), has the same suffix as the Germanic word.[2] Kroonen relates it to the old word for “half”, sām- and Latin sēmi-, and reconstructs *smH-oro-.[5]

The regular modern form would keep /u/, as most southern dialects do (Alemannic German Summer, Bavarian Summer, Luxembourgish Summer); the vowel ⟨o⟩ before the nasal is of Central and Low German origin.[1][3] The EWA finds it from the 15th century in Middle Franconian and credits Luther's Bible with spreading it over the whole language area;[3][4] Pfeifer dates the change to about the 16th century, as in Sonne.[3][4]

Earliest recorded meaning

Old High German sumar is recorded from the third quarter of the 8th century in glosses, then in the Benedictine Rule, the Hildebrandslied, the Tatian and Notker, meaning “summer”; the genitive (des) sumares meant “in summer”.[3][8][9] In Middle High German sumer was also the name of a fever.[3]

Semantic evolution

The oldest Germans knew only two seasons, and Sommer was the warm half of the year in contrast to winter, as in the pair Sommer und Winter “all year round”;[10][11] Walther von der Vogelweide already uses it so.[10][11] Once spring and autumn were distinguished, it was narrowed to the season between them.[11] In poetry it can stand for a year of life (Hagedorn: sechzehn Sommer alt).[10][11]

The white threads of small spiders drifting in late summer have been called fliegender Sommer since the 17th century, later Altweibersommer, which also names a spell of fine autumn weather.[4] The compound Sommersprosse “freckle” clarifies an older sprusse;[4][7] Pfeifer dates it to the end of the 17th century, Duden to the 16th.[4][7] Sommerfrische “summer holiday in the country” arose about 1600 around Bolzano and spread at the end of the 19th century, when Sommerfrischler (1869) appeared.[10]
