Etymologically, the entry records: From fail (verb) + deadly, modelled on fail-safe. 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 fail-deadly, spelled F-A-I-L---D-E-A-D-L-Y, and any other sequence of those letters, regardless of how natural it feels, is a misspelling in standard orthography.
