Morphology

mental + dexterity

The phrase combines 'mental' (relating to the mind) with 'dexterity' (skillfulness or nimbleness), so the sense 'ability to think quickly and intelligently' is directly derivable from the constituent meanings. This adjective+noun composition and its clear metaphorical extension (akin to 'mental agility' in many languages) make the meaning transparent to learners who know both words.

Etymology

Mental dexterity comes from the image of dexterity, a word that first meant 'skill with the hands' — quick, clever fingers — while mental refers to the 'mind'. So, imagine those fast, skillful fingers moved into the head; that's why mental dexterity means 'the ability to think quickly and well'.
