Etymologically, the entry records: An abbreviation of coronavirus disease + 19 from 2019, the year the virus was discovered. Coined by the World Health Organization on February 11, 2020. Intended to avoid stigma by not referring to a place, animal, career, or group of people. 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 COVID-19, spelled C-O-V-I-D---1-9, and any other sequence of those letters, regardless of how natural it feels, is a misspelling in standard orthography.
