iit also means unbreakable bonds,so strangely,it is a good omen for marriage
Though the deck may have appeared in 1996, that meaning sounds like one of the old ones that, really, don't hold a lot of water in modern society. Rather like the definition of the Queen/Swords as a divorced woman. Back in the day when divorced women were rare, that was a useful definition. A reader could say, "The person you're looking for is a divorced woman..." and the sitter would say, "By gosh! That must be Mrs. Smith, she's the only divorced woman in town..." But now, your sitter would probably say, "Which one? I know a dozen...."
So the definition becomes rather pointless. Especially as it's also sexist. There is no male card that is a "divorced" man. The definition applies only to the one Queen, as if that state of non-marriage defines her more than her being, well, a prize winning scientist or investigative journalist
Likewise, I suspect this definition of "unbreakable bonds" meaning a "good omen" for marriage is probably sadly old-fashioned. As if marriage is the best possible state for two people, and a couple that can't divorce is going to be better off than a couple that can. That comes from a certain bias that has no basis in reality, back when or now. It's just that back when, being in a bad marriage was often more useful (to the woman at least) than not being married at all. Society back when being brutal to spinsters.
But that's a slim degree of "better." Rather like saying that at least in prison you're getting three square meals a day. Yeah, you're being fed. But you're still in prison and going to be there for the rest of your life. Is that really a "good" omen?
