What does affiance mean?
Affiance is a formal, somewhat archaic English noun denoting a solemn pledge of marriage — what we would today call an engagement or betrothal. Historically, an affiance was more than a casual promise: in medieval and early modern Europe, a betrothal could carry legal and religious weight, and breaking one was a serious matter. The word derives from the Old French 'afier', meaning to trust or pledge, ultimately from Latin roots relating to faith and fidelity, which also gave us 'fiance', 'fidelity', and 'confidence'. Beyond its matrimonial sense, affiance once carried a broader meaning of trust or reliance placed in another person, though this sense is now obsolete. Today the word appears chiefly in literary, historical, or legal writing about courtship customs, lending an air of gravity and antiquity wherever it occurs. Readers encountering it should understand it as a weighty synonym for engagement, redolent of an era when promises were binding contracts.
nounA formal pledge or promise of marriage; a solemn engagement to wed. In older usage, it can also mean a general trust or confidence placed in someone.

- (Archaic) Trust or confidence reposed in someone.
"Their affiance was sealed with a quiet ceremony before the family gathered for the wedding itself."
"The young couple exchanged rings as a token of their affiance, though the wedding was still a year away."
"In Shakespeare's England, an affiance was often as binding as marriage itself."
Rarely used in the plural; when it appears, it typically refers to multiple betrothal agreements, often in historical or legal records.
"The parish register recorded several affiances that winter, each awaiting a wedding date."
Before 'getting engaged' was a thing, couples gave their 'affiance' — a word so formal it sounds like signing a treaty, because that's essentially what medieval betrothal was.

Etymology of affiance
Affiance entered English in the late Middle Ages via Old French 'afier', meaning to trust or to pledge faith, which itself descends from the Late Latin 'affidare', to entrust. This Latin root, built on 'fides' (faith), is shared with words such as 'fidelity', 'confidence', and 'infidel'. The word originally carried the general sense of placing trust in someone before narrowing to its dominant sense: a formal promise of marriage. Its cousin 'fiance' arrived later by the same route, preserving the person rather than the pledge.
