Vernacular form of member of the cattle species. Bovine mammalian quadruped, domesticated during pre-history as a source of meat and leather. The female is able to also give milk and the male 'bull' is a symbolical given the property of strength. It's excrement (when dry) is a useful fuel source.
Relatively placid; tends to herd for mutual protection. Provides labour opportunities for cowherds and milkmaids.
Not normally eligible to become a knight, landed or court noble, or archbishop. Possibly a good candidate for royalty, where there is a capable First Minister already in place.
