'articulatorily' originates from Modern English, specifically formed from the adjective 'articulatory' + the adverbial suffix '-ly', where '-ly' meant 'in the manner of'.

'articulatory' derives from the noun 'articulator' and ultimately from Latin 'articulare' and 'articulus'. Latin 'articulare' (from 'articulus' 'a small joint') gave sense both of 'jointing' and later 'uttering (distinctly)'; through Late Latin and Old French influences the root entered Middle English and became 'articulate'/'articulatory', leading to the Modern English adverb 'articulatorily'.

Initially connected with 'joints' or 'joining' (from Latin 'articulus'), the sense shifted toward 'utter clearly' and 'divide into distinct parts' and has come to mean 'relating to speech production (articulation)' in modern linguistic usage.
