particles (these may be further categorized, see Hale 1987:19–20); (ii) enclitic forms of
personal pronouns; and (iii) accentless verbal forms. Although difficulties of script and
interpretation mean that we do not always have a clear idea of which words were truly clitics
in early Indo-European languages, it appears that Wackernagel’s Law is best observed (given
certain modifications) with enclitics of class (i), while pronouns also show a tendency to
associate with the verb phrase. The behavior of accentless verb forms is more complicated.
In Vedic Sanskrit, verbs are usually accented in subordinate clauses but unaccented in main
clauses, and Wackernagel saw an exact parallel to this in the Modern German verb-second
order of main clauses, but verb-final order in subordinate clauses (1892:427). However,
this correspondence appears to be fortuitous, and since Delbr
¨
uck (1900:82), scholars have
argued that only the copula verb was truly an enclitic.
It seems likely that Proto-Indo-European did not have fixed word order, and the attempt
to fit Proto-Indo-European syntax into the straitjacket of typological universals has now
largely been superseded by more nuanced assessments of word placement (see in particular
the criticisms of Lehmann 1974 in Watkins 1976). The unmarked order appears to have
been head-final, although pragmatic and prosodic factors may have played an important
role. Note, for example, that Vedic Sanskrit, Greek, and Hittite all allow constituents to be
frontedtoatopic position to the left of the sentence proper (Hale 1987:14f.).
The reconstruction of subordination and embedding for Proto-Indo-European continues
to provoke debate. Even the reconstruction of relative clauses is controversial. Most of
the Indo-European languages mark relative clauses with the reflex of either
∗
yo- (Greek,
Sanskrit, Celtic, etc.) or
∗
k
w
o-/
∗
k
w
i- (Hittite, Latin, Tocharian, etc.). Although some scholars
have argued that the use of two different markers shows that Proto-Indo-European did not
have relative clauses of any type, others reconstruct both relative pronouns for the parent
language, with an original distinction between
∗
k
w
o-/
∗
k
w
i-, functioning as a restrictive or
defining relative, and
∗
yo- as an appositional or descriptive relative (see Hettrich 1988 for
discussion).
Those who deny the existence of any relative pronouns in Proto-Indo-European envis-
age a development of relatives, and other subordinate clause types, in the daughter lan-
guages from earlier paratactic structures. Indeed, Kiparsky (1995) argues that the difficulty
of reconstructing any complementizers for Proto-Indo-European implies that there was no
complementation at all. However, the reconstruction of participles (§3.6.3), and compound-
ing (§3.5.1), suggests that some forms of syntactic embedding were possible, and further
research in this area is needed.
