  • Most acronyms can be written as capital letters or with only an initial capital letter.
  • Some acronyms are so established that they are now ‘normal’ words, generally used without conscious awareness of their original full form. These words should be written in lower-case letters. Examples include:

laser

light amplification by stimulated emission of radiation

radar

radio detection and ranging

quango

quasi-autonomous non-governmental organization

scuba

self-contained underwater breathing apparatus
