Title: On the sources of (un)accentedness
ABSTRACT
Recent work on the distribution of unaccentedness in the lexicon of
Tokyo Japanese has found a concentration of unaccented words in very
specific areas, which are to a large extent defined in prosodic terms.
Thus 4-mora words are in their majority unaccented in both native
words and loans. On the other hand, 1-2 mora words and 5-mora words
are in the majority accented in both native words and loans. For
3-mora words we find a split: They are in the majority unaccented in
native words, but accented in loans. What is relatively clear is that
unaccentedness is some kind of default for words of these specific
shapes. What is less clear is the prosodic rationale of the particular
distribution of (un)accentedness. The goal of the talk is to
investigate the underlying structural reason, and to develop a formal
account in optimality-theoretic phonology.The regular pitch accent pattern of Tokyo Japanese (i.e., the pattern
that is not lexically marked on a morpheme-by-morpheme basis, but
emerges, e.g., in loanwords) is characterized by two constraints
widely seen at work in other languages: Rightmostness (if the word has
an accent, it should fall on the last foot in the word) and
Nonfinality (the accent should not fall on a subconstituent that is
final in the word). There is a clear tension between these two
constraints, which is in many languages resolved by priority ranking
(Nonfinality beats Rightmostness in cases of conflict). Seen in this
light, unaccentedness is another way of dealing with the conflict: By
not assigning an accent, the conflict disappears.More precisely, the guiding idea is the following: For words of
specific prosodic profiles (such as LLLL), unaccentedness is a default
because it fulfills both Nonfinality and Rightmostness (no accent
means no violation of either constraint). For other shapes, such as
LLL and LLLLL, both constraints can be fulfilled even by accented
words, so unaccentedness brings no prosodic benefit and is avoided
since it violates the ?-Accent constraint requiring words to be
accented. For short (one- to two-mora) words, a constraint calling for
the construction of the “perfect prosodic word” (a word coextensive
with a single foot) plays an important role. Other cases of perfect
word effects to be presented include Serbian and Danish.
