Disquisition is a noun that refers to an elaborate discussion of a particular subject.

Our word of the day originates from the Latin word quaerere (kwa WOAR ay) which means ‘seek’ or ‘ask.’ This word evolved into disquisition and referred to an investigation. But more recently the word has come to refer to a lengthy and elaborate discussion — the kind you might have in a college classroom, not in a bar. For example: When I asked about the video game my son was playing, I wasn’t expecting at disquisition on the history of video games. But two hours later, I learned the game he was playing was called Old West Shootout.
