'anagramming' originates from English, specifically from the word 'anagram,' which comes from Greek 'anagrammatismos,' where 'ana-' meant 'again' and 'gramma' meant 'letter.'

'anagrammatismos' transformed into the French word 'anagramme,' and eventually became the modern English word 'anagram' and its verb form 'anagramming.'

Initially, it meant 'transposing the letters of a word or phrase,' and this meaning has remained the same in modern usage.
