The quality or state of being fluent; the ability to speak, read, or perform something smoothly and without awkwardness or hesitation.
Formed by combining 'fluent' (flowing smoothly) with the suffix '-ness' (state of being), creating a noun that emphasizes the characteristic of smooth, easy expression.
Interestingly, fluentness in music and language use almost identical brain regions—when a musician has fluentness on their instrument, they're using the same neural pathways as a polyglot speaking their fifth language!
