As I said, the idea is that the suffix was polysemic, with its use in the pronouns being for emphasis. OTOH, its use in Indo-Iranian is much later than its integration into the PIE noun paradigm, so that may well be a different suffix.Alces wrote:That seems like a fairly plausible explanation for the origin of the thematic neuter nom./acc. sg. *-óm ending, but I don't see why such a morpheme might be suffixed to personal pronouns.
Alces wrote:A personal pronoun coming from a phrase meaning "I am here"? Sounds fishy to me; I'd like to see if there are any attested examples of such a development. Also, if Skt ahám is from an athematic verb ending in *-mi, wouldn't we expect to see some trace of the *-i?
If it's old enough, it could have been petrified into a pronoun before the "primary" - "secondary" opposition was formed by adding /i/ to form the present tense endings. But I don't like the derivation from a verb much either.
You're probbly right about Nom. 1st Du; it's the same process like with the other nominative forms. On the accusative, I think it went as follows - there were emphatic / stressed lengthened equivalents to the short forms with /e/ already in (late) PIE (s. Latin me:, te:), and then the normal accusative /m/ was added to them. My understanding of the Dual is that it originally didn't distinguish Nom. and Acc. at all, so the /-m/ is just a Post-PIE import from the singular.Alces wrote:The nom. 1du. vā́m could also reflect the same ending if it's from PIE *we + *-Hóm, with vowel contraction. Likewise the accusative forms mā́m (1sg.) āvā́m (1du.), tvā́m (2sg.), yuvā́m (2du.) could reflect the same ending, added to Ringe's reconstructed forms *m̥mé, *n̥h₃mé, *twé and *uh₃wé (with some stem remodelling too in the 1sg. and 2du.). You might be able to alternatively explain the endings of the acc. sg. forms as coming from a-stem acc. sg. *-am (masculine/neuter), *-ām (feminine), just as the -ān in acc. 1pl. asmā́n and acc. 2pl. yuṣmā́n is probably just the a-stem acc. pl. ending. But, glancing at Wikipedia, it doesn't look like -ām is an acc. du. ending in any nominal stem class, so I don't know how else the endings of these accusative dual forms can be explained.
Kloekhorst gives an overview of his reconstructions in his Hittite Etymplogical Dictionary, p. 135 ff. (PDF here.) On the whole, there are still significant differences in opinion on the details, and I'd recommend to read several accounts in order not to be captured by one school's interpretation.(If anybody knows of a good resource that could help me with IE personal pronouns, I'd much appreciate it... the only things I have to refer to here are the very cursory remarks made by Ringe [2006], who says I should look at Katz [1998] if I want more detail, except I don't have that book, and the basic overview in Fortson [2004].)
That would have to be NAGD, as all old IE languages, including Anatolian, attest gen. pl. -om. This is a statement that has been made concerning the stage of PIE before Anatolian split off; I personally find it convincing. Concerning Post-Anatolian PIE, a big group of core languages excluding Anatolian (I don't know about Tocharian) also shares developments like the Loc. Pl. -su and the differentiation of Dat. Pl. vs. Instr. Pl. based on something like *-bho-/-mo- vs. *-bhi-/-mi- for the non-o-stems and an Instr. Pl. *-oHis in the o-stems. There are some regional developments like the use of /m/ for Dat. Instr. Pl. in Balto-Slavic and Germanic vs. /bh/ in the other families.Zju wrote:I've also read that PIE didn't have plural caseforms of cases other than N A D - is that true?
