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 *akwā-, "water." *Akwā- became *ahwō- in Germanic by Grimm's Law and other sound changes. To this was built the adjective *ahwjō-, "watery." This then evolved to *awwjō- or *auwi-, which in pre-English became *ēaj-, and finally ēg or īeg 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 īnsula "island," a component of paenīnsula, "almost-island," whence our peninsula.
