To declare or assert something openly and boldly, often with confidence or solemnity.
From Old French 'avouer' meaning 'to acknowledge or confess,' derived from Latin 'advocare' (to call to oneself), which evolved to mean asserting ownership or truth.
Avow is a wonderfully bold verb that suggests more confidence and formality than simply 'saying'—when you avow something, you're staking your reputation on its truth.
