Did you look up the definition of "word"? How is "DME" a "word"? As Ron
implies, "VOR" *could* be considered a "word", but the vast majority of
us
spell it out and don't consider it to be a "word".

Then what do you think it is? It's not an abbreviation

They *are* both abbreviations. "DME" is a shortened form of the phrase
"Distance Measuring Equipment", while "VOR" is a shortened form of the
phrase "Very High Frequency Omnidirectional Range".
