'alliterationist' originates from the word 'alliteration,' which comes from Latin 'alliteratio,' where 'ad-' meant 'to' and 'littera' meant 'letter.'

'alliteratio' transformed into the English word 'alliteration,' and eventually the term 'alliterationist' was coined to describe someone skilled in this technique.

Initially, it referred to the use of repeated consonant sounds, and over time it evolved to describe a person skilled in this technique.
