Plural of gaiety; instances of cheerfulness, lightheartedness, bright and festive occasions, or lively social gatherings.
From Old French 'gai' meaning merry or cheerful, which may have Germanic roots. The suffix '-ty' (via French '-té') creates an abstract noun, and '-ies' forms the plural.
The word 'gaiety' exploded in popularity during the Victorian era when people became obsessed with describing the increasingly elaborate social events and balls they were attending—it was basically their word for 'party vibes.'
