It's kinda difficult to describe what I mean exactly, but I couldn't think of an example. Maybe I can add it later if I come up with one.
The art/science of naming for example these complex situations within a single word:
• (not mine) "Waited a long time to read book. Read book. Didn't like book. Life now empty." "There should be a word for that."
• The empty but also content feeling you get after finishing a story or movie because you're "life" within the story stops. There could be a word for this.
