to put in pledge

Pledge \Pledge\, n. [OF. plege, pleige, pledge, guaranty, LL.
   plegium, plivium; akin to OF. plevir to bail, guaranty,
   perhaps fr. L. praebere to proffer, offer (sc. fidem a trust,
   a promise of security), but cf. also E. play. [root]28. Cf.
   {Prebend}, {Replevin}.]
   1. (Law) The transfer of possession of personal property from
      a debtor to a creditor as security for a debt or
      engagement; also, the contract created between the debtor
      and creditor by a thing being so delivered or deposited,
      forming a species of bailment; also, that which is so
      delivered or deposited; something put in pawn.
      [1913 Webster]

   Note: Pledge is ordinarily confined to personal property; the
         title or ownership does not pass by it; possession is
         essential to it. In all these points it differs from a
         mortgage [see {Mortgage}]; and in the last, from the
         hypotheca of the Roman law. See {Hypotheca}. --Story.
         Kent.

   3. A hypothecation without transfer of possession.

   4. Anything given or considered as a security for the
      performance of an act; a guarantee; as, mutual interest is
      the best pledge for the performance of treaties. "That
      voice, their liveliest pledge of hope." --Milton.
      [1913 Webster]

   5. A promise or agreement by which one binds one's self to
      do, or to refrain from doing, something; especially, a
      solemn promise in writing to refrain from using
