the.com/winter squash

means A hard-shelled, thick-fleshed squash (like butternut, acorn, or pumpkin) harvested in fall and able to keep through winter without refrigeration.

from Squash itself borrows from the Narragansett word askutasquash, meaning roughly 'eaten raw/uncooked,' which English settlers clipped down to 'squash' in the 1600s — the plant came from the Americas, where it had been cultivated for thousands of years before Europeans ever saw it. The 'winter' half of the name is simple storage logic, not botany or season of growth: these thick-skinned varieties mature in late summer and fall but their dense flesh and tough rinds let them sit in a cellar for months, so they became the squash you ate through winter — as opposed to the thin-skinned 'summer squash,' eaten fresh and fast.
