Yearn \Yearn\ (y[~e]rn), v. t. [imp. & p. p. {Yearned}; p. pr. &
   vb. n. {Yearning}.] [Also earn, ern; probably a corruption of
   OE. ermen to grieve, AS. ierman, yrman, or geierman, geyrman,
   fr. earm wretched, poor; akin to D. & G. arm, Icel. armr,
   Goth. arms. The y- in English is perhaps due to the AS. ge
   (see {Y-}).]
   To pain; to grieve; to vex. [Obs.] ``She laments, sir, for
   it, that it would yearn your heart to see it.'' --Shak.

         It yearns me not if men my garments wear. --Shak.
