Morphology

thinking + cap

The compound combines the transparent words 'thinking' and 'cap' but its meaning is figurative: it refers to adopting a focused mindset rather than a literal hat. A B1 learner who knows both words can likely infer the general idea (prepare to think), but the conventional metaphor of 'putting on' a mental stance is not fully literal or predictable without exposure, so it is only partially transparent.

Etymology

The noun thinking cap comes from the simple picture of putting on a special hat, the cap, to get into a thinking mood, the thinking. That's why saying 'put on your thinking cap' means 'to focus and think carefully'.
