Re-mark \Re-mark"\ (r?-m?rk"), v. t. [Pref. re- + mark.]
   To mark again, or a second time; to mark anew.
   [1913 Webster]

The Collaborative International Dictionary of English v.0.48:

Remark \Re*mark"\ (r?-m?rk"), v. t. [imp. & p. p. Remarked
   (-m?rkt"); p. pr. & vb. n. Remarking.] [F. remarquer; pref.
   re- re- + marquer to mark, marque a mark, of German origin,
   akin to E. mark. See Mark, v. & n.]
   1. To mark in a notable manner; to distinquish clearly; to
      make noticeable or conspicuous; to piont out. [Obs.]
      [1913 Webster]

            Thou art a man remarked to taste a mischief. --Ford.
      [1913 Webster]

            His manacles remark him; there he sits. --Milton.
      [1913 Webster]

   2. To take notice of, or to observe, mentally; as, to remark
      the manner of a speaker.
      [1913 Webster]

   3. To express in words or writing, as observed or noticed; to
      state; to say; -- often with a substantive clause; as, he
      remarked that it was time to go.
      [1913 Webster]

   Syn: To observe; notice; heed; regard; note; say.

   Usage: Remark, Observe, Notice. To observe is to keep
          or hold a thing distinctly before the mind. To remark
          is simply to mark or take note of whatever may come
          up. To notice implies still less continuity of
          attention. When we turn from these mental states to
          the expression of them in language, we find the same
          distinction. An observation is properly the result of
          somewhat prolonged thought; a remark is usually
          suggested by some passing occurence; a notice is in
          most cases something cursory and short. This
          distinction is not always maintained as to remark and
          observe, which are often used interchangeably.
          "Observing men may form many judgments by the rules of
          similitude and proportion." --I. Watts. "He can not
          distinguish difficult and noble speculations from
          trifling and vulgar remarks." --Collier. "The thing to
          be regarded, in taking notice of a child's
          miscarriage, is what root it springs from." --Locke.
          [1913 Webster]
