'acronymically' originates from 'acronym,' specifically the word 'acronymic,' where 'acro-' meant 'top' and '-onym' meant 'name.'

'acronymic' changed from the Greek word 'akron' and 'onoma' and eventually became the modern English word 'acronym.'

Initially, it meant 'a word formed from the initial letters of other words,' and this meaning has largely remained the same in modern usage.
