It also is known as cobnut or filbert nut according to species. A cob is roughly spherical to oval, about 15--25 mm (0.59--0.98 in) long and 10--15 mm (0.39--0.59 in) in diameter, with an outer fibrous husk surrounding a smooth shell. A filbert is more elongated, being about twice as long as its diameter. The nut falls out of the husk when ripe, about 7 to 8 months after pollination. The kernel of the seed is edible and used raw or roasted, or ground into a paste. The seed has a thin, dark brown skin, which sometimes is removed before cooking.

The main factors in determining if someone is a compulsive talker are talking in a continuous manner or stopping only when the other person starts talking, and others perceiving their talking as a problem. Personality traits that have been positively linked to this compulsion include assertiveness, willingness to communicate, self-perceived communication competence, and neuroticism. Studies have shown that most people who are talkaholics are aware of the amount of talking they do, are unable to stop, or do not see it as a problem.
