Etymologically, the entry records: Appears 1850 in Cottage economy, attributed to William Cobbett (but not found in any editions published during his life). From Italian pesto, from Latin pistus (“crushed, pounded”), from Latin pīnsō (“to pound, beat, crush”). Cognate to pestle. 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 pesto, spelled P-E-S-T-O, and any other sequence of those letters, regardless of how natural it feels, is a misspelling in standard orthography.
