accouer

Accouer is a very rare, archaic verb from hunting and horse-handling vocabulary: tying a horse's halter to the tail of the horse ahead in a line, or, in venery (deer hunting), cornering or wounding a deer at the shoulder. It comes from Old French, ultimately from queue ("tail").

• Les palefreniers accouaient les chevaux pour la traversée. — The stable hands tied the horses tail-to-halter in a line for the crossing.
• Les chiens ont fini par accouer le cerf. — The hounds eventually cornered the deer.
• Ce terme de vénerie, accouer, est tombé en désuétude. — This hunting term, accouer, has fallen out of use.

This word is obsolete outside specialized hunting/equestrian history texts — there's no everyday mistake to flag, since a learner will essentially never need to produce it.
