3rd person personal pronoun

[Bert]

There is no nominative form for the third person personal pronoun.
By the time that αá½￾τός developed into a personal pronoun, it gets used at times in the nominative to emphasize the subject or to indicate the gender of the subject.
In Homeric Greek, does the subject get expressed to do this, or does αá½￾τός as intensive pronoun get used for this.

[Skylax]

According to Chantraine's Homeric Grammar, there is no difference here between Homeric and Classical Greek : αá½￾τός can be "strong" or "weak". When "strong", αá½￾τός is emphatic, underlining either an opposition ("he, not another") or the identity ("he, yes, the same person"). In a weakened meaning, αá½￾τός "plays the part" of a 3rd person personal pronoun, even in the nominative, but of course it is not compulsory.
