Morphology

ace + up + one's + sleeve

The pieces give a clear clue: an "ace" (a high-value card) hidden "up one's sleeve" evokes a concealed, powerful resource, so a learner who knows these words can plausibly infer a secret advantage. However, understanding the idiomatic use relies on cultural knowledge (hiding an ace to cheat) and the full figurative sense is not guaranteed for a B1 learner without exposure, so it is only partially transparent.

Etymology

The idiom ace up one's sleeve may come from old card games where a player secretly hid an ace in their sleeve to play at the right moment. That's why it now means 'a secret advantage' you keep until you need it.
