Morphology
The literal image of 'put' + 'finger' + 'on' (placing or pointing with a finger) maps plausibly onto 'identify or pinpoint' something, so a learner who knows the parts can often infer the figurative sense. However, the identification sense is a metaphorical extension of the physical action rather than a strictly compositional meaning, and cross‑linguistic realizations vary, so it is not fully predictable for an average B1 learner without prior exposure.
Etymology
The phrase put one's finger on comes from the simple image of touching a small spot to show exactly where something is. If you put your finger on a problem, you have found the exact cause, so the phrase means 'to identify' or 'understand' something clearly.
