Etymologically, the entry records: Probably from a(minobuty)l(id)ene + -dronic (“calcium metabolism regulator, from ethidronic acid derivatives, EThane-1-HYDRoxy-1,1- diphosphONIC acid”) acid. 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 alendronic acid, spelled A-L-E-N-D-R-O-N-I-C- -A-C-I-D, and any other sequence of those letters, regardless of how natural it feels, is a misspelling in standard orthography.
