Forms

déchéance f (plural déchéances)[1] Old French decaance;[2] Monet has decheance in 1636.[2]

Etymology

It is formed from French déchoir + -ance.[2][3][4][5] The verb is from Vulgar Latin *dēcadō, from cadō (“to fall”).[4] Wiktionary compares Late Latin decadentia, and names décadence, borrowed from Latin, as its doublet.[1]

Littré compares Old Occitan dechazensa, Spanish decadencia and Italian scadenza.[6]

Earliest recorded meaning

It is first recorded as decaance in 1174, in Guernes de Pont-Sainte-Maxence's life of Thomas Becket, for a moral fall: Mais jo quit dire veir de cele decaance “But I think I speak the truth about that fall”.[2][6]

Semantic evolution

From its first sense of falling morally, the word developed two legal senses: the loss of a right as a penalty or by lapse of time (1636, decheance de bourgeoisie) and removal from an office or a throne, first found in Robespierre's speech on the trial of Louis XVI in 1792.[7][2] The deposition of a sovereign is the sense Littré illustrates with Louis XVI.[6]

In modern use it is also the physical or mental decline that comes with age or illness (déchéance physique).[2][8][9]

Timeline

  • 1174 – Decaance “moral fall” in Guernes de Pont-Sainte-Maxence.[2][7]
  • 1636 – Monet records decheance de bourgeoisie, the loss of a right.[2][7]
  • 1792 – Robespierre uses it for removal from office, of Louis XVI.[2][7]
