Morphology

mark + someone's + card

The sense 'to give someone important information or a warning' is not directly obvious from the literal meanings of 'mark' (to notice or make a sign) and 'card' (a physical card or record), though there is a partial link if 'mark' is interpreted as 'note in a record' and 'card' as a personal record. Because the connection requires a figurative extension of 'card' and some idiomatic usage knowledge, a B1 learner who only knows the constituents would probably not fully predict the meaning.

Etymology

Mark someone's card may come from old card games where players wrote notes on a paper card; if a player was tricky others would mark that player's card to warn everyone to watch out. That's why today it means 'to give someone important information or a warning' before they meet or deal with someone.
