'aphorismatic' originates from Greek via Latin and modern English, specifically the word 'aphorismos' (Greek) / 'aphorism' (English), where 'aphorizein' meant 'to define' or 'to separate out'.

'aphorismatic' changed from Greek 'aphorismos' to Late Latin/Medieval Latin 'aphorismus', then to English 'aphorism', after which the adjectival formation using the suffix '-atic' produced 'aphorismatic' in modern English.

Initially it referred to 'a concise statement or definition' (an 'aphorism'), but over time it evolved to describe the quality 'pertaining to or resembling aphorisms'—i.e., concise and pointed expression.
