frequency and agreement

[Hartmut Haberland]

Cases of 'clitic doubling' in Modern Greek are clearly not optional
since clitic doubling in this language has a pragmatic function (roughly
Topic marking, although this interacts in an intricate way with VS/SV
word order). This doesn't mean you cannot do statistics on this
phenomenon; but it is not a case of (socio)linguistic variation, rather
it codes (pragmatic) meaning.

The following two articles which I wrote with Johan van der Auwera
mainly deal with clitic resumption in relative clauses, but contain
ample references to the general discussion on clitic doubling:

1987. Doubling and Resumption in Modern Greek. In: Melétes gia tin
ellinikí glóssa/Studies in Greek Linguistics. Proceedings of the 8th
annual meeting of the Department of Linguistics, Faculty of Philosophy,
Aristotelian University of Thessaloniki, 27-29 April 1987 (A Festschrift
for John Chadwick), 323-334

1990. Topics and Clitics in Greek Relatives, Acta Linguistica Hafniensia
22:127-157

(The latter reference is probably more easily accessible.)
