Multidimensionality. I know, it sounds like a made-up word. One of those words with too many syllables. A big word designed to impress when a shorter, simpler word would suffice. A word like that is actually called a sesquipedalian. Go figure.
Multidimensionality has a specific definition, but like many other words, the definition shifts, or is tweaked, depending on the subject being spoken of and its context. My most recent brush with the word, or its concept, was a bit of an accident.
