Fair (yet to be seen) and gentle people of this realm forum. I pose you a question: What (I dare ask) is Socionics? Now, don't be so hasty as to dismiss me; for with one seemingly straight forward question, I ask two!

First: What is Socionics in a "dictionary" definition sense, but please refrain from the narrow minded actions of cut-and-paste and or direct quoting in total place of your own words; I wish that you would all give the most rigid definition you can muster, in your own terms.

Second: What is Socionics in an applicatory sense; is Socionics a literal psychological 'hierarchy' of (rigid?) personality archetypes that exist in-place of constantly shifting (usually) reactionary, and or, scenario based sludge of the frontal lobe.

Or is it something different?

tl;dr What is Socionics in a general sense, and What is Socionics intended use (be it sociological descriptions of the workings of relationships; or psychological descriptions of ((rigid?)) personality types.)
