Etymology: "Aestival" comes directly from Latin "aestivalis," the adjective built on "aestas," the Latin word for summer. The Latin root is related to "aestus," meaning heat or glowing warmth, which explains why the summer word carries the sense of heat as well as season. The Romans used "aestivalis" for things belonging to the warm months, and English took the term over in its Latin form to describe what pertains to summer. The word has a close relative in "estival," the same adjective with the initial "a" dropped, which is the more common spelling in modern dictionaries. Both forms sit comfortably alongside "hibernal," the opposite term for winter, and the pair shows how English scholars and writers often reached back to Latin to build precise seasonal vocabulary.
