Etymology

Origin of acorn

before 1000; Middle English acorne (influenced by corn ¹ ), replacing akern, Old English æcern, æcren mast, oak-mast; cognate with Old Norse akarn fruit of wild trees, Middle High German ackeran acorn, Gothic akran fruit, yield < Germanic *akrana-; alleged derivation from base of acre is dubious if original reference was to wild trees

Explanation

The nut, or fruit, that grows on oak trees is called an acorn. Chicken Little thought the sky was falling when an acorn fell on his head. Don't make that same mistake. Acorns are a distinctive nut that's often found on forest floors where oak trees grow. They are smooth and greenish, set in a rough brown base that's shaped like a little cup. The acorn is a seed, able to sprout roots if it falls in the right place, eventually growing into a new oak tree. Many animals eat acorns, some stockpiling the nuts for weeks. In Old English, æcern means "nut," from a Germanic origin.
