Etymology

Origin of summer¹

First recorded before 900; Middle English somer, Old English sumor; cognate with Dutch zomer, German Sommer, Old Norse sumar “summer”; akin to Sanskrit sámā “season, half-year, year,” Old Irish sam-, Old Welsh ham, Welsh haf “summer”

Origin of summer²

First recorded in 1275–1325; Middle English somer, from Anglo-French; Old French somier “packhorse, beam,” from unattested Vulgar Latin saumārius, equivalent to Latin sagm(a) “packsaddle” (from Greek ságma ) + -ārius noun suffix; see -ary, -er ²

Explanation

Summer is the season after spring and before autumn. In the summer, the weather is warmer and many students get a break from school. If you live in the Northern Hemisphere, summer lasts from June to September, and if you travel in December to Australia or somewhere else in the Southern Hemisphere, you'll get to experience summer all over again. When fancy people talk about what they do during the summer, they may use it as a verb: "Oh, we summer in Maine."
