Acquaintance arises from occasional intercourse; as, our acquaintance has been a brief one. We can speak of a slight or an intimate acquaintance. Familiarity is the result of continued acquaintance. It springs from persons being frequently together, so as to wear off all restraint and reserve; as, the familiarity of old companions. Intimacy is the result of close connection, and the freest interchange of thought; as, the intimacy of established friendship.
