Here's a great example of shooting oneself in the foot:
Since the sentence in question just tries to amplify the advice of "don't use it's for the possessive" but without adding anything substantive to the discussion, I'm just going to remove it.
Frankly, I'm not entirely sure where the possessive its comes from. It's clearly a modern formation. Old and Middle English have hit for it (still retained in some American dialects in some contexts), with genitive his (not retained, to my limited knowledge). There is no older form like ittes or hittes to contract down to it's.
Shakespeare doesn't seem to use it's, though most editions you see will have modernized the orthography. For example, working from a facsimile of Antony and Cleopatry from the first folio, starting around line 1381, it appears that it is used by itself as a possessive, as in "It is iust so high as it is, and mooues with it owne organs." Caveat: I haven't checked every play.
It appears that what's really going on here is that, sometime relatively recently, the convention was adopted that its would indicate the possessive and it's would indicate the contraction. This was pretty clearly done on the basis of similarity to his/her/our/etc., but this is clearly just a handy mnemonic and not the consequence of some fundamental principle. Interestingly, this convention does not apply to one's. I would expect that this distinction only started to be made when it's began to supplant 'tis, but it would be very interesting to have more specific evidence.
Unfortunately for us here, this is one case where paper has a major advantage over bits. If you look at a paper copy, you can be pretty sure that no one has helpfully "corrected" the orthography in the process of conversion. -dmh 15:11, 12 August 2005 (UTC)
I replaced the examples "this is its space ship" and "this book is its" because they did not in any way help the reader understand the usage. --SteveG23 14:46, 9 March 2007 (UTC)
I would find the explanation why its supposedly lacks an apostrophe erroneous, accordingly online etymology 'its' derived from a contamination of 'it's' which itself came to replace the old neuter possessive pronoun 'his' which became solely masculine. (cf German and Dutch and most Germanic languages having the same genitive case for masculine and neuter), the simple reason that 'its' has no such apostrophe is convention of a contamination becoming widespread and etymologically it's incorrect use. Factual inaccuracies aside, I also find it subjectively debatable that 'its' is a possessive pronoun or adjective, rather, I find it to be a simple possessive noun phrase like 'John's' or 'The King's', this is how it started and it still functions grammatically like that. One for instance cannot say 'Those eyes of its' but one can say 'Those eyes of mine' or 'of his' et cetera, as one also cannot say 'Those eyes of The King's.' 213.84.222.243 19:26, 28 August 2009 (UTC)
Here are a couple of vaguely-related notes.
Regarding etymology, I'm convinced that the OED has more information, but I'm not near my copy to check on it. I'm sure we could shed light on this by reading the OED's entry carefully.
Regarding usage, we are all accustomed to the stricture that spelling "its" with an apostrophe is flat-out wrong. It turns out, though, that this stricture is fairly modern. Reputable printers published works with possessive "it's" well into the 19th century. Right now I'm reading Frances Burney's Cecilia, (late 18th century) and the spelling "it's" is used throughout.
I fail to follow the logic in the first bulleted item of the Usage section:
"Henry's" is certainly the possessive form of "Henry". It is already a possessive term; according to the logic above, it shouldn't need an apostrophe. I'm not arguing with the conclusion: it's certainly an error in modern usage to spell "its" with an apostrophe. I'm just saying that one cannot reason one's way to that conclusion; it's a contingent fact of history, not a logical necessity. ACW 14:16, 25 February 2010 (UTC)
In the "pronoun" section, the text implies it can be used as either a possessive pronoun or a pronoun in general. I am not aware of any use of its as a pronoun other than as a possessive pronoun, e.g.:
Is there such a usage? Facts707 17:42, 10 May 2010 (UTC)
Its and one’s are not used without nouns --Backinstadiums (talk) 12:31, 4 December 2020 (UTC)
Similarly to it's. JMGN (talk) 09:38, 13 October 2024 (UTC)
