Etymologically, the entry records: From Middle English side, from Old English sīde (“side, flank”), from Proto-Germanic *sīdǭ (“side, flank, edge, shore”), from Proto-Indo-European *sēy- (“to send, throw, drop, sow, deposit”). Cognate with Saterland Frisian Siede (“side”), West Frisian side … Root origin matters for spelling because borrowed morphemes (Greek, Latin, Old French, Old English) carry their source-language orthographic conventions into modern English, which is why historical etymology is often the cleanest predictor of whether a cluster like "-ough", "-eau", or "-tion" will appear. For readers arriving here from a spelling check, the authoritative guidance is: the correct English form is side, spelled S-I-D-E, and any other sequence of those letters, regardless of how natural it feels, is a misspelling in standard orthography.

Etymology

From Middle English side, from Old English sīde (“side, flank”), from Proto-Germanic *sīdǭ (“side, flank, edge, shore”), from Proto-Indo-European *sēy- (“to send, throw, drop, sow, deposit”). Cognate with Saterland Frisian Siede (“side”), West Frisian side (“side”), Dutch zijde, zij (“side”), German Low German Sied (“side”), German Seite (“side”), Danish and Norwegian side (“side”), Swedish sida (“side”). The LGBTQ slang sense was coined by sex therapist and author Joe Kort in 2010 and popularized in 2013. The sense was coined by analogy with top and bottom and based on the metaphor of a box which has a top, bottom, and sides.
