Attain \At*tain"\ ([a^]t*t[=a]n"), v. t. [imp. & p. p.
   {Attained} (-t[=a]nd"); p. pr. & vb. n. {Attaining}.] [Of.
   atteinen, atteignen, atainen, OF. ateindre, ataindre, F.
   atteindre, fr. L. attingere; ad + tangere to touch, reach.
   See {Tangent}, and cf. {Attinge}, {Attaint}.]
   1. To achieve or accomplish, that is, to reach by efforts; to
      gain; to compass; as, to attain rest.

            Is he wise who hopes to attain the end without the
            means?                                --Abp.
                                                  Tillotson.

   2. To gain or obtain possession of; to acquire. [Obs. with a
      material object.] --Chaucer.

   3. To get at the knowledge of; to ascertain. [Obs.]

            Not well attaining his meaning.       --Fuller.

   4. To reach or come to, by progression or motion; to arrive
      at. ``Canaan he now attains.'' --Milton.

   5. To overtake. [Obs.] --Bacon.

   6. To reach in excellence or degree; to equal.

   Syn: To {Attain}, {Obtain}, {Procure}.

   Usage: Attain always implies an effort toward an object.
          Hence it is not synonymous with obtain and procure,
          which do not necessarily imply such effort or motion.
          We procure or obtain a thing by purchase or loan, and
          we obtain by inheritance, but we do not attain it by
          such means.
