\It\, pron. [OE. it, hit, AS. hit; cf. D. het. [root]181. See
{He}.]
The neuter pronoun of the third person, corresponding to the
masculine pronoun he and the feminine she, and having the
same plural (they, their or theirs, them).
Note: The possessive form its is modern, being rarely found
      in the writings of Shakespeare and Milton, and not at
      all in the original King James's version of the Bible.
      During the transition from the regular his to the
      anomalous its, it was to some extent employed in the
      possessive without the case ending. See {His}, and
      {He}. In Dryden's time its had become quite established
      as the regular form.
            The day present hath ever inough to do with it
            owne grief.                        --Genevan
                                               Test.
            Do, child, go to it grandam, child. --Shak.
            It knighthood shall do worse. It shall fright all
            it friends with borrowing letters. --B. Jonson.
Note: In the course of time, the nature of the neuter sign i
      in it, the form being found in but a few words, became
      misunderstood. Instead of being looked upon as an
      affix, it passed for part of the original word. Hence
      was formed from it the anomalous genitive it,
      superseding the Saxon his. --Latham.
            The fruit tree yielding fruit after his (its)
            kind.                              --Gen. i. 11.
Usage: It is used,
1. As a substance for any noun of the neuter gender; as, here
   is the book, take it home.
2. As a demonstrative, especially at the beginning of a
   sentence, pointing to that which is about to be stated,
   named, or mentioned, or referring to that which apparent
   or well known; as, I saw it was John.
         It is I; be not afraid.               --Matt. xiv.

   Often, in such cases, as a substitute for a sentence or

   this.

   snows; it rains.
