Syn: Admission; access; entrance; initiation.
Usage: {Admittance}, {Admission}. These words are, to some
       extent, in a state of transition and change.
       Admittance is now chiefly confined to its primary
       sense of access into some locality or building. Thus
       we see on the doors of factories, shops, etc. ``No
       admittance.'' Its secondary or moral sense, as
       ``admittance to the church,'' is almost entirely laid
       aside. Admission has taken to itself the secondary or
       figurative senses; as, admission to the rights of
       citizenship; admission to the church; the admissions
       made by one of the parties in a dispute. And even when
       used in its primary sense, it is not identical with
       admittance. Thus, we speak of admission into a
       country, territory, and other larger localities, etc.,
       where admittance could not be used. So, when we speak
       of admission to a concert or other public assembly,
       the meaning is not perhaps exactly that of admittance,
       viz., access within the walls of the building, but
       rather a reception into the audience, or access to the
       performances. But the lines of distinction on this
       subject are one definitely drawn.
