'acronymic' originates from 'acronym', which is derived from Greek, specifically the word 'akron', meaning 'tip' or 'end', and 'onoma', meaning 'name'.

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

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