Inverse Attraction.—An antecedent nominative or (oftener) accusative may be attracted to the case of the relative. The attracted antecedent is often prefixed for emphasis to the relative clause, which thus separates it from the verb it governs or by which it is governed. Cp.
τά_σδε (for αἵδε)
δ' ἅ_σπερ εἰσορᾷς . . . χωροῦσι
a. The main clause may contain a resumptive demonstrative pronoun; as
τὸν ἄνδρα τοῦτον, δν πάλαι ζητεῖς . . ., οὗτός ἐστιν ἐνθάδε
b. The rare cases of the inverse attraction of the dative are suspected or admit another explanation (
c. So with adverbs: καὶ ἄλλοσε (for ἄλλοθι) ὅποι ἂν ἀφίκῃ ἀγαπήσουσί δε
