If you've ever felt like you need a translator to help understand all the weird jargon that comes with owning a vehicle in Aotearoa, you have come to the right place.

Initialism vs. Acronym

Ever wondered about the labels for these shortened terms? The difference comes down to how you say them.
  • An abbreviation is any shortened form of a word
  • An initialism is when you say the individual letters, like R-U-C
  • An acronym us when the letters form a new, pronounceable word, like NAS

A great example of the grey area is WOF. Some people say the letters 'W-O-F' (making it an initialism), while many others pronounce it as a single word, 'woff' (making it an acronym). So, you're not wrong either way.
