Tenaille
TYPE OF DEFENSIVE-WORK
Tenail; Tenails; Tenalia; Priests cap; Un pan coupé
A tenaille (archaic tenalia) is an advanced defensive-work, in front of the main defences of a fortress, which takes its name from resemblance, real or imaginary, to the lip of a pair of pincers. It is "from French, literally: tongs, from Late Latin tenācula, pl of tenaculum".
