After \Aft"er\ ([.a]ft"t[~e]r), a. [AS. [ae]fter after, behind;
   akin to Goth. aftaro, aftra, backwards, Icel. aptr, Sw. and
   Dan. efter, OHG. aftar behind, Dutch and LG. achter, Gr.
   'apwte`rw further off. The ending -ter is an old comparative
   suffix, in E. generally -ther (as in other), and after is a
   compar. of of, off. [root]194. See {Of}; cf. {Aft}.]
   1. Next; later in time; subsequent; succeeding; as, an after
      period of life. --Marshall.

   Note: In this sense the word is sometimes needlessly combined
         with the following noun, by means of a hyphen, as,
         after-ages, after-act, after-days, after-life. For the
         most part the words are properly kept separate when
         after has this meaning.

   2. Hinder; nearer the rear. (Naut.) To ward the stern of the
      ship; -- applied to any object in the rear part of a
      vessel; as the after cabin, after hatchway.

   Note: It is often combined with its noun; as, after-bowlines,
         after-braces, after-sails, after-yards, those on the
         mainmasts and mizzenmasts.

   {After body} (Naut.), the part of a ship abaft the dead flat,
      or middle part.

After \Aft"er\, adv.
   Subsequently in time or place; behind; afterward; as, he
   follows after.

         It was about the space of three hours after. --Acts. v.
                                                  7.

   Note: After is prefixed to many words, forming compounds, but
         retaining its usual signification. The prefix may be
         adverbial, prepositional, or adjectival; as in after-
         described, after-dinner, after-part. The hyphen is
         sometimes needlessly used to connect the adjective
         after with its noun. See {Note} under {After}, a., 1.
