'anaptyxis' originates from Greek, specifically the word 'anaptuxis,' where 'ana-' meant 'up' or 'again' and 'ptysis' meant 'folding.'

'anaptuxis' was adopted into Late Latin as 'anaptyxis,' and eventually became the modern English word 'anaptyxis.'

Initially, it referred to the act of unfolding or opening, but over time it evolved into its current linguistic meaning of inserting a vowel sound within a word.
