'architectonic' originates from Greek, specifically the word 'arkhitektonikos' (ἀρχιτεκτονικός), where 'arkhi-' meant 'chief' and 'tekton' meant 'builder'.

'architectonic' changed from Late Latin 'architectonicus' and Medieval Latin forms into Middle English via Old French/Latin-influenced forms and eventually became the modern English word 'architectonic'.

Initially it meant 'pertaining to the master builder or to building/construction', but over time it evolved to its current meanings of 'relating to architecture' and more broadly 'structural or systematic'.
