acronym (English)

Where does "acronym" come from?

The word 'acronym' is a modern invention, first appearing in German in the early 1900s before entering English in 1940. It was crafted by combining the Ancient Greek 'akron' (meaning 'peak' or 'beginning') and 'onyma' (meaning 'name'), following the naming patterns of words like 'synonym' and 'homonym.' These roots ultimately trace back to a Proto-Indo-European term for 'sharp,' reflecting the idea of taking only the pointed, initial letters of a phrase to create a new name.
