Evaluating phonological status : significance of paradigm uniformity vs. prosodic group effects
(2007)
A central concern of linguistic phonetics is to define criteria for determining the phonological status of sounds or sound properties observed in phonetic surface form. Based on acoustic measurements we show that the occurrence of syllabic sonorants vs. schwa-sonorant sequences in German is determined exclusively by segmental and prosodic structure, with no paradigm uniformity effects. We argue that these findings are consistent with a uniform representation of syllabic sonorants as schwa sonorant sequences in the lexicon. The stability of schwa in CVC-suffixes (e.g. the German diminutive suffix -chen), as opposed to its phonetic absence in a segmentally comparable underived context, is argued to be conditioned by the prosodic organisation of such suffixes external to the phonological word of the stem.
Trubetzkoy's recognition of a delimitative function of phonology, serving to signal boundaries between morphological units, is expressed in terms of alignment constraints in Optimality Theory, where the relevant constraints require specific morphological boundaries to coincide with phonological structure (Trubetzkoy 1936, 1939, McCarthy & Prince 1993). The approach pursued in the present article is to investigate the distribution of phonological boundary signals to gain insight into the criteria underlying morphological analysis. The evidence from English and Swedish suggests that necessary and sufficient conditions for word-internal morphological analysis concern the recognizability of head constituents, which include the rightmost members of compounds and head affixes. The claim is that the stability of word-internal boundary effects in historical perspective cannot in general be sufficiently explained in terms of memorization and imitation of phonological word form. Rather, these effects indicate a morphological parsing mechanism based on the recognition of word-internal head constituents. Head affixes can be shown to contrast systematically with modifying affixes with respect to syntactic function, semantic content, and prosodic properties. That is, head affixes, which cannot be omitted, often lack inherent meaning and have relatively unmarked boundaries, which can be obscured entirely under specific phonological conditions. By contrast, modifying affixes, which can be omitted, consistently have inherent meaning and have stronger boundaries, which resist prosodic fusion in all phonological contexts. While these correlations are hardly specific to English and Swedish it remains to be investigated to which extent they hold cross-linguistically. The observation that some of the constituents identified on the basis of prosodic evidence lack inherent meaning raises the issue of compositionality. I will argue that certain systematic aspects of word meaning cannot be captured with reference to the syntagmatic level, but require reference to the paradigmatic level instead. The assumption is then that there are two dimensions of morphological analysis: syntagmatic analysis, which centers on the criteria for decomposing words in terms of labelled constituents, and paradigmatic analysis, which centers on the criteria for establishing relations among (whole) words in the mental lexicon. While meaning is intrinsically connected with paradigmatic analysis (e.g. base relations, oppositeness) it is not essential to syntagmatic analysis.
Identity effects in phonology are deviations from regular phonological form (i.e. canonical patterns) which are due to the relatedness between words. More specifically, identity effects are those deviations which have the function to enhance similarity in the surface phonological form of morphologically related words. In rule-based generative phonology the effects in question are described by means of the cycle. For example, the stress on the second syllable in cond[ɛ]nsation as opposed to the stresslessness of the second syllable in comp[ǝ]nsation is described by applying the stress rules initially to the sterns thereby yielding condénse and cómpensàte. Subsequently the stress rules are reapplied to the affixed words with the initial stress assignment (i.e. stress on the second syllable in condense, but not in compensate) leaving its mark in the output form (cf. Chomsky and Halle 1968). A second example are words like lie[p]los 'unloving' in German, which shows the effects of neutralization in coda position (i.e. only voiceless obstruents may occur in coda position) even though the obstruent should 'regularly' be syllabified in head position (i.e. bl is a wellformed syllable head in German). Here the stern is syllabified on an initial cycle, obstruent devoicing applies (i.e. lie[p]) and this structure is left intact when affixation applies (i.e. lie[p ]Ios ) (cf. Hall 1992). As a result the stern of lie[p]los is identical to the base lie[p].
