1. the part of an arrow having a notch for the bowstring; the notch itself
[origin: 14th century; Middle English nocke notched tip on the end of a bow; akin to Middle Dutch nocke summit]
A long bow and a strong bow,
and let the sky grow dark!
The cord to the nock, the shaft to the ear,
and the king of Koth for a mark!
Song of the Bossonian Archers
