What does exuberancy mean?
Exuberancy is a noun denoting the quality of being exuberant — that is, marked by unrestrained enthusiasm, high spirits, or vigorous, overflowing energy. It applies chiefly to people and their behaviour: someone's exuberancy shows in their laughter, movement, and irrepressible good cheer, though it can also describe the lush, profuse growth of plants. The word derives from the Latin 'uber', meaning fertile or abundant, via 'exuberare', to be abundantly fruitful, and entered English in the early modern period alongside its sibling 'exuberant'. In practice, exuberancy is a rare variant of the far more common 'exuberance'; modern usage overwhelmingly favours the latter, so encountering 'exuberancy' often signals literary style, historical text, or a deliberate choice of an unusual word. Its connotations are warmly positive, suggesting vitality rather than mere noise.
The state or quality of being exuberant; effusive enthusiasm, vitality, or joyous energy.
"His boyish exuberancy was infectious, and soon the whole team was laughing."
Prefer 'exuberance' in contemporary writing; 'exuberancy' is an accepted but uncommon variant.

Rarely used; the plural appears mainly in literary contexts describing multiple distinct displays or kinds of liveliness.

Exuberancy is the forgotten twin of 'exuberance' — same Latin roots, same meaning, but it lost the popularity contest centuries ago.

Etymology of exuberancy
Exuberancy comes from the Latin verb 'exuberare', meaning to be abundantly fruitful, formed from 'ex-' (thoroughly) and 'uber' (fertile, abundant). English adopted both 'exuberance' and the '-ancy' variant during the 17th century, when many abstract nouns of this shape were coined from Latin stems. The two forms coexisted, but 'exuberance' became the dominant choice, leaving 'exuberancy' as a rarer alternative still recognised in larger dictionaries.
