So now we move onto the minors. I'll be taking them 4 at a time to get us through them quickly--and I won't be spending as much time on the Opposite/blocked/upsidedown. So do Chime in if you see anything I seem to be missing on those scores.
I'll also be viewing Wands as Fire/Energy and Swords as Air/Mind/Communications. If you view Wands as Air, Swords as Fire, just flip them.
Aces: Aces are the spark, the initial energy of the suit. Unfocused, undirected, pure and new. So for Wands, new energy. For Swords, a new idea. For Cups, a new emotion. For Pentacles, new luck (or health).
If we reverse the Aces then the most immediate, opposite meaning is that there is no spark of energy, idea, emotion or luck. Or that the potential for these is blocked. In image, the reversed card shows these aces pointing down--going down, instead of rising up. The overturned cup is emptied of all it's liquid.
So what does this mean in a reading? It likely means that the querent SHOULD be feeling a stirring of that ace, but isn't. So, the querent should be feel excited at a new prospect (energy, ambition), but doesn't (reversed wand). He should feel the start of a new idea, or a new speech he wants to give, but there's nothing (reversed sword). He should feel emotions stirring as he, say, gazes at attractive people or his newborn child. But he feels nothing, empty (reversed Cup). He should feel that his luck is turning, the beginnings of renewed health but doesn't (reversed pents).
Reversed Pents, in addition, could indicate a failed anticipation--the querent anticipated a hint that money would be coming his way, and there's no such hint. Things remain speculative, rather than real and solid.
Reversed Aces are like trying to start a fire, and getting nothing. No smoke, no spark. It's the hope of a hope that never comes. There's not even the feeling that something was there and died--it was never there in the first place. You just feel that something that could have become "it" ought to have been there.
