...and some acronyms have been used in everyday conversation so much that they appear in the English language as a 'normal' word and most folks don't even realise it's an acronym.
As en example, I was shooting pretend 'Laser' beams at my brothers in the early 70's, but it wasn't until my school Physics lessons, I learnt it was an acronym. Light Amplification by the Stimulated Emission of Radiation (LASER) if I remember rightly, but as I just lived on the edge and didn't Google it to be sure, may be wrong.
