ETYMOLOGY:
Alteration (influenced by isle) of Middle English ilond, from Old English egland : g, eg; see akw-- in Appendix I + land, land; see lendh- in Appendix I.
WORD HISTORY:
It may seem hard to believe, but Latin aqua, “water,” is related to island, which originally meant “watery land.” Aqua comes almost unchanged from Indo-European *akw-, “water.” *Akw- became *ahw- in Germanic by Grimm's Law and other sound changes. To this was built the adjective *ahwj–, “watery.” This then evolved to *awwj– or *auwi–, which in pre-English became *aj–, and finally g or eg in Old English. Island, spelled iland, first appears in Old English in King Alfred's translation of Boethius about a.d. 888; the spellings igland and ealond appear in contemporary documents. The s in island is due to a mistaken etymology, confusing the etymologically correct English iland with French isle. Isle comes ultimately from Latin nsula “island,” a component of paennsula, “almost-island,” whence our peninsula.
