'aromatical' originates from Latin, specifically the word 'aromaticus', from Greek 'arōmatikos', where 'arōma' meant 'spice' or 'sweet smell'.

'aromatical' changed from Middle English 'aromaticall' (borrowed via Latin/Old French forms) and eventually became the modern English adjective 'aromatical' (now rare; largely replaced by 'aromatic').

Initially, it meant 'pertaining to aromatic substances or possessing a scent', but over time the simpler form 'aromatic' became standard and 'aromatical' grew rare or archaic while retaining the general meaning 'fragrant'.
