        acquaintance with him.

           acquaintances.

     Syn: Familiarity; intimacy; fellowship; knowledge.
  
     Usage: Acquaintance, Familiarity, Intimacy. These words
            mark different degrees of closeness in social
            intercourse. 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.

                  nearer acquaintance with him.     --Addison.
            [1913 Webster]
  
                  We contract at last such a familiarity with them
                  as makes it difficult and irksome for us to call
                  off our minds.                    --Atterbury.
            [1913 Webster]
  
                  It is in our power to confine our friendships
                  and intimacies to men of virtue.  --Rogers.
