For me, it's not single cards that carry the meaning, it's usually more than one so I see things in specific groups. Like 2 of Cups, Lovers and the Heirophant would be one combination that would speak of marriage to me. Throw in the Page of Cups, Empress and Sun and I'd be seeing something indicating that children were going to be coming along soon. Or that possibly one was already on the way. And 4 of Wands is another that might occur in combination with the others. But usually it's the combinations that will tell the tale for me rather than only one card.
I think once you learn the cards that
can indicate a certain outcome, then you'll also be able to pick up the groupings of cards in a spread that can mean a certain outcome. Just be aware that no one card always means any one thing.
For instance, in a reading for a woman expecting a child, seeing the Hierophant and 4 of Wands in the same spread, especially right next to each other, could mean a baby shower is going to come up. These two cards speak of traditional things and a celebration. See what I mean? If the 3 of Cups and Judgment are there, then a surprise baby shower thrown secretly by the woman's friends might be indicated. (Speaking of that, why don't people give the expectant dads a baby shower of their own? I think they should.)
