'alphabetarian' originates from the Latin word 'alphabetum,' which means 'alphabet,' combined with the suffix '-arian,' indicating a person associated with or practicing something.

'alphabetum' transformed into the English word 'alphabet,' and eventually became the modern English word 'alphabetarian' by adding the suffix '-arian.'

Initially, it meant 'a person learning the alphabet,' and this meaning has largely remained the same in modern usage.
