it

来自古英语hit,来自PIE*ko,这个，这里，词源同he,here,him.后为与him相区别，字母h有意识脱落。比较I.

it

it: [OE] It (or hit, as it was in Old English) comes ultimately from the same prehistoric Germanic demonstrative stem form. *khi-, as produced he. The possessive form its is a comparatively recent development, dating from the end of the 16th century; until then, his was used for ‘its’.
=> he

it (pron.)

Old English hit, neuter nominative and accusative of third person singular pronoun, from Proto-Germanic demonstrative base *khi- (cognates: Old Frisian hit, Dutch het, Gothic hita "it"), from PIE *ko- "this" (see he). Used in place of any neuter noun, hence, as gender faded in Middle English, it took on the meaning "thing or animal spoken about before."

Whether the charmer sinner it or saint it,
If the folly grow romantic, I must paint it.
[Pope, "Moral Essays," 1735]

The h- was lost due to being in an unemphasized position, as in modern speech the h- in "give it to him," "ask her," "is only heard in the careful speech of the partially educated" [Weekley]. It "the sex act" is from 1610s; meaning "sex appeal (especially in a woman)" first attested 1904 in works of Rudyard Kipling, popularized 1927 as title of a book by Elinor Glyn, and by application of It Girl to silent-film star Clara Bow (1905-1965). In children's games, meaning "the one who must tag the others" is attested from 1842.

2. "It's" (with an apostrophe) should be used only as a contraction for "it is".

it's（带撇号）只能用作itis的缩约形式。
