Synonym discussion
Sense: noun/1
Ability is the broadest term — it covers both natural and learned skills ('She has the ability to solve complex equations'). Capacity suggests an upper limit or potential ('His capacity for learning is enormous'). Power often refers to a specific physical or mental capability ('The power of speech was affected by the injury'). Faculty is the most specific: it denotes an inborn, often sensory or cognitive power such as sight, hearing, or reason ('the faculty of memory'). Unlike ability, faculty is rarely used for learned skills; unlike capacity, it does not imply a maximum. In everyday speech, ability and power are more common than faculty, which sounds more formal. Use faculty when you want to refer to one of the basic mental channels through which humans perceive and process the world.

Etymology
Faculty entered English in the 1300s from the Old French word 'faculté', meaning 'power, ability, or authority'. This came from the Latin 'facultās', which meant 'capability, power, or opportunity', itself derived from 'facilis' (easy to do). The Latin root 'facere' (to do, make) is also the source of words like 'factory' and 'manufacture'. The meaning shifted from 'personal ability' to 'a branch of learning' (1400s) and later to 'the teachers of a university' (1600s), following the logic that a university's teaching body possesses the authority to teach in a given field.
