There are two special cases and then one very big generalization.
Special case 1: (definite) personal pronouns. If the NP is one of six (definite) "personal pronouns" (note: this is a technical term) -- 1sg (nominative I), 2 (nominative you), 3sg fem (nominative she), 3sg masc (nominative he), 1pl (nominative we), 3pl (nominative they) -- its determinative possessive form is suppletive, not a simple concatenation of morphemes: respectively, my, your, her, his, our, their.
There are several other items usually labeled as possessives which go by the big generalization, rather than having their possessives stipulated, for instance:
generic one: One should never count one's chickens before they're hatched.
anaphoric indefinite one: The big cat's tail is shorter than the small one's.
compound indefinite pronouns: We're collecting everybody's opinions.
Special case 2: NPs without a possessive.
There are several classes of NPs that simply lack a possessive. (Geoff Pullum and I talked about a number of these in a 1996 LSA paper, the handout for which is available on my website.) Some are single words:
expletive there: *There's being no food in the refrigerator upsets me.
headless modifiers: demonstratives: This cat's tail is short. *That's is long.
headless modifiers: quantifiers: We interviewed many subjects. *We took down each's opinion.
headless modifiers: independent possessives: Your cat's tail is short. *Mine's is long.
(Notice that in the last case we end up with unacceptable mine's.)
and some are longer phrases --
"nominal gerunds" (possessive + gerund): Your walking me home really pleases me. *Your walking me home's really pleasing me is a surprise to everyone.
infinitival clauses: For you to walk me home really pleases me. *For you to walk me home's really pleasing me is a surprise to everyone.
(These lists are merely illustrative, not exhaustive.)
The big generalization: Z.
Otherwise, the possessive form of a NP x has a Z suffix on the last word w
of x
I've said this with some care. In particular, I did NOT say that the possessive form of x uses the possessive form of its last word w, since that wouldn't provide possessives for NPs that end in words that are not nouns (like the friend I was telling you about or everyone I know), since such words of course do not have possessive forms.
And now we make a prediction about the determinative possessive corresponding to the pet bear of a friend of mine (using an alternative expression of possession which has the preposition of): it should just follow the big generalization: a friend of mine's pet bear, with Z suffixed to the last word, mine, of the possessor phrase a friend of mine. That's where we started.
Just to wrap up this description, here's how Z is realized:
Realization of Z. The possessive Z is suppressed if w itself ends in a Z suffix (the birds' wings). Otherwise, possessive Z has the same phonology as plural Z and 3sg present Z:
the basic variant is z (bird's, Chicago's);
for a word ending in a sibilant, epenthesize schwa between it and the z (Max's, judge's);
otherwise, for a word ending in a voiceless consonant, devoice the z (cat's, Rick's).
The careful reader will have noticed that I haven't said anything about
the personal pronoun it.
I'm saving that for a future posting.
