What does affiancing mean?
Affiancing is the present participle of the verb affiance, a now largely archaic English term meaning to pledge or bind a person by a formal promise of marriage — in effect, to betroth them. In its transitive sense, it describes one party (historically often parents arranging a match) binding another in engagement, as when a monarch was said to be affiancing his daughter to a foreign prince; in its reflexive sense, it can describe a couple entering into a mutual promise of marriage. The word derives from Medieval Latin affidare, 'to entrust or pledge,' through Old French, sharing its root with fiducia and fides — the Latin words for trust and faith that also gave English 'fidelity' and 'confidence.' Today affiancing appears almost exclusively in historical fiction, legal documents, and scholarly writing about marriage customs, where its formal, ceremonial tone suits descriptions of dynastic alliances and solemn betrothals. Its more recognizable relative, the adjective 'affianced,' survives slightly more often in phrases such as 'the affianced couple.'

"The medieval chronicle records how the king was affiancing his eldest daughter to the Duke of Burgundy."
"After a courtship of two years, they were affiancing quietly, with only their immediate families present."
Before couples got 'engaged,' they were 'affianced' — a solemn pledge rooted in the same Latin word for trust that gives us 'fidelity' and 'confidence.'

Etymology of affiancing
Affiancing descends from the verb affiance, which entered Middle English from Old French affier ('to trust, pledge'), itself derived from Medieval Latin affidare, formed on Latin fidere and fides — trust and faithfulness. This makes it a cousin of modern words built on the same root of trust, including 'fidelity,' 'confide,' 'confidence,' and 'affidavit.' The betrothal sense developed in medieval legal and social usage, when a formal pledge of marriage carried contractual weight, and the word has retained that solemn, formal character ever since.
