Etymologically, the entry records: From Middle English asma, asme, from Medieval Latin asthma, asma, from Ancient Greek ἆσθμα (âsthma, “laborious breathing, asthma”). The spelling was changed to add -th- in the 16th century to match the Greek etymological roots. 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 asthma, spelled A-S-T-H-M-A, and any other sequence of those letters, regardless of how natural it feels, is a misspelling in standard orthography.
