Etymologically, the entry records: From Middle English hardenen, equivalent to hard + -en. Cognate with Danish hærdne (“to harden; cure”), Swedish hårdna (“to harden”), Norwegian herdne (“to harden”), Icelandic harðna (“to harden”). 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 harden, spelled H-A-R-D-E-N, and any other sequence of those letters, regardless of how natural it feels, is a misspelling in standard orthography.
