Back to basics then
Just trying to understand why it seems everyone else has a different 'word' than I do.
Ah. I see. So you're wondering why so many agree that "wait" is right of the Hanged Man, but no one seems to have heard of "fateful decision"? I think, to answer that, you need to get back to basics. Here is the Rider Waite interpretation and corresponding Crowley. These two are the ones that almost all creators of tarot books will use as a springboard for their meanings. IF you read a book where the writer didn't pay any attention to these, only their own feelings, then that might account for why you're not getting the same meanings for these cards as others.
The Hanged Man:
RWS: Waite has no one interpretation for this, but says: "It should be noted (1) that the tree of sacrifice is living wood, with leaves thereon; (2) that the face expresses deep entrancement, not suffering; (3) that the figure, as a whole,
suggests life in suspension"
Bold mine there. That one part there would explain why so many see it as "waiting" rather than a "final" decision. It doesn't seem "final" at all given those notes--especially as Waite insists that this card isn't about death or endings, but life. So, it would seem right to read this card as a pause, as being in the middle of a process, rather than a fait accompli.
Thoth/Crowley Interpretation: "The Hanged Man is a symbol for the turning points in life, showing up a need to stop and assess a situation. We're hanging in the air until we find a new view of the things around us, a proper way to rearrange or restart."
Again, this seems more in line with "waiting" then with a fateful, final decision. So let me ask you--WHY do you see this card as a fateful, final decision? What book did you read? And how does the image imply this to you? Most books agree that readers should not apply Christian metaphors to the image, as it is not about a Christ figure dying for others. It relates to an old form of punishment for traitors who were hung by one foot, upside-down. In many early decks, the card was called "The Traitor." And though this might seem to suggest the card is about betrayal, it's actually about the person who sees things "upside down" from the rest of us. Others see him as "betraying" them, but he is being true to himself. And willing to sacrifice their opinion of him in order to do so.
This is why his expression is serene rather than suffering. He is finally seeing the world as he always should have, and is absorbing this new perspective (see also the story of Odin hanging from the tree).
