Do \Do.\, n.
   An abbreviation of {Ditto}.

Do \Do\ (d[=o]), n. (Mus.)
   A syllable attached to the first tone of the major diatonic
   scale for the purpose of solmization, or solfeggio. It is the
   first of the seven syllables used by the Italians as manes of
   musical tones, and replaced, for the sake of euphony, the
   syllable Ut, applied to the note C. In England and America
   the same syllables are used by mane as a scale pattern, while
   the tones in respect to absolute pitch are named from the
   first seven letters of the alphabet.

Do \Do\, v. t. or auxiliary. [imp. {Din}; p. p. {Done}; p. pr. &
   vb. n. {Doing}. This verb, when transitive, is formed in the
   indicative, present tense, thus: I do, thou doest (?) or dost
   ?, he does (?), doeth (?), or doth (?); when auxiliary, the
   second person is, thou dost. As an independent verb, dost is
   obsolete or rare, except in poetry. ``What dost thou in this
   world?'' --Milton. The form doeth is a verb unlimited, doth,
   formerly so used, now being the auxiliary form. The second
   pers, sing., imperfect tense, is didst (?), formerly didest
   (?).] [AS. d?n; akin to D. doen, OS. duan, OHG. tuon, G.
   thun, Lith. deti, OSlav. d?ti, OIr. d['e]nim I do, Gr. ? to
   put, Skr. dh[=a], and to E. suffix -dom, and prob. to L.
   facere to do, E. fact, and perh. to L. -dere in some
   compounfds, as addere to add, credere to trust. ??? Cf.
   {Deed}, {Deem}, {Doom}, {Fact}, {Creed}, {Theme}.]
   1. To place; to put. [Obs.] --Tale of a Usurer (about 1330).

   2. To cause; to make; -- with an infinitive. [Obs.]

            My lord Abbot of Westminster did do shewe to me late
            certain evidences.                    --W. Caxton.

            I shall . . . your cloister do make.  --Piers
                                                  Plowman.

            A fatal plague which many did to die. --Spenser.

            We do you to wit [i. e., We make you to know] of the
            grace of God bestowed on the churches of Macedonia.
                                                  --2 Cor. viii.
                                                  1.

   Note: We have lost the idiom shown by the citations (do used
         like the French faire or laisser), in which the verb in
         the infinitive apparently, but not really, has a
         passive signification, i. e., cause . . . to be made.

   3. To bring about; to produce, as an effect or result; to
      effect; to achieve.

            The neglecting it may do much danger. --Shak.

            He waved indifferently 'twixt doing them neither
            good not harm.                        --Shak.

   4. To perform, as an action; to execute; to transact to carry
      out in action; as, to do a good or a bad act; do our duty;
      to do what I can.

            Six days shalt thou labor and do all thy work. --Ex.
                                                  xx. 9.

            We did not do these things.           --Ld. Lytton.

            You can not do wrong without suffering wrong.
                                                  --Emerson.
      Hence: To do homage, honor, favor, justice, etc., to
      render homage, honor, etc.

   5. To bring to an end by action; to perform completely; to
      finish; to accomplish; -- a sense conveyed by the
      construction, which is that of the past participle done.
      ``Ere summer half be done.'' ``I have done weeping.''
      --Shak.
