n. leader, esp. old and experienced

Het dir bruniik rek-grohiik Ulfeidr, kriid muz ahrk sunvaar, bruniik kinbok Sahqon Tah.
Here died the savage she-wolf Ulfeidr, slayer of men and beasts, and savage leader of the Crimson Pack.
(Word Wall for Tah, Animal Allegiance)

Connotates someone that leads as a result of age, wisdom, or experience.

May derive from bok ‘age’, though bok only refers to a period of time. Possibly a compound of kiin ‘born’ and bok, ‘born of age’.
