Etymology

It is inherited from Middle English ile, borrowed from Old French ile (earlier isle, modern French île),[2][3][4] from Latin īnsula (“island”),[2][3][5] a word of uncertain origin;[3][5][6] following the ancients, some derive it from in (“in”) and the ablative of salum (“open sea”), "that which is in the sea".[7][5][8] Middle French restored the spelling with s in the 15th century after Latin, and English followed, rarely before the late 1500s and regularly from Spenser on.[3][2][9]

Earliest recorded meaning

An island: about 1290, in the South English Legendary;[2] Barnhart dates ile probably about 1225.[3]

Semantic evolution

The older spelling ile survived until about 1700.[2] In the Wycliffite Bible isles rendered the Hebrew word for lands beyond the sea, as in isles of the Gentiles.[2] Isle is now chiefly literary or used of small islands, except in names such as the British Isles and the Isle of Man.[2][10] Its s also spread to the unrelated island, from Old English īgland.[11][3]
