Phonological alternations are often specific to morphosyntactic context. For example, stress shift in English occurs in the presence of some suffixes, -al, but not others, -ing: "pa.rent, pa."ren.tal, "pa.ren.ting. In some cases a phonological process applies only in words of certain lexical categories. Previous theories have stipulated that such morphosyntactically conditioned phonology is word-bounded. In this paper we present a number of long-distance morphologically conditioned phonological effects, cases where phonological processes within one word are conditioned by another word or the presence of a morpheme in another word. We provide a model, Cophonologies by Phase, which extends Cophonology Theory, intended to capture word-internal and lexically specified phonological alternations, to cyclically generated syntactic constituents. We show that Cophonologies by Phase makes better predictions about the long-distance morphologically conditioned phonological effects we find across languages than previous frameworks. Furthermore, Cophonologies by Phase derives such effects without requiring the phonological component to directly reference syntactic features or structure.
This article expands on cophonologies by phase, a model of the interface between morphology and phonology, which was introduced in Sande & Jenks 2018. The crucial innovation of cophonologies by phase is the enhancement of lexical or vocabulary items to include morpheme-specific constraint weights. These weights modify the default phonological grammar of the language only in the domain of evaluation that contains the triggering morpheme, where domains are determined by syntactic phase boundaries. The interactions of the default grammar and morpheme-specific constraint weights function as cophonologies (Orgun 1996, Anttila 2002, Inkelas & Zoll 2005, 2007) in that they result in morphosyntactic construction-specific phonological grammars. Here, cophonologies by phase is shown to provide a unified account of syntactically, morphologically, and lexically conditioned phonological alternations, phenomena that have been analyzed using distinct theoretical tools in previous work. In order to demonstrate the application of cophonologies by phase to a diverse set of interface interactions, this article considers three case studies of phonological alternations in Guébie (ISO: gie), an endangered Kru language, each conditioned by a different set of extraphonological factors.*
This paper presents data bearing on two key issues in morphophonological theory: 1) the domain of phonological evaluation, and 2) the item-versus processmorphology debate. I present data from Guébie (Kru) [Côte d'Ivoire] showing that imperfective aspect is exponed by a scalar shift in surface tone, which can affect either the tone of the inflected verb, or the subject noun phrase. There are four tone heights in Guébie, and the first syllable of a verb can underlyingly be associated with any of the four tones. In imperfective contexts only, that initial verb tone lowers one step on the four-tone scale. If the tone of the verb is already low, the final tone of the subject raises one step instead. This paper demonstrates that in order to account for the crossword tonal effects of the imperfective morpheme, phonological evaluation must scope over more than one word at a time; specifically, it must scope over a syntactic phase. Additionally, I show that with phonological constraint rankings sensitive to morphosyntactic construction, no abstract phonological underlying form of the imperfective morpheme is necessary.
Morphologically conditioned phonology, where a particular phonological alternation or requirement holds only for a subset of lexical items or in a subset of morphological contexts, is well documented. This paper expands on the literature by examining phonological alternations where two independent triggering morphemes must both be present for a phonological alternation to apply. Several cases of doubly morphologically conditioned phonological alternations, from a diverse set of languages, are described. The existence of morphologically conditioned phonology with two triggers informs our models of the interface between morphology and phonology, in that phonological operations must be able to reference the presence of more than one morpheme simultaneously. A range of possible analyses are considered, including those set in Stratal OT, Indexed Constraint Theory, Cophonology Theory and Cophonologies by Phase Theory. A Cophonologies by Phase account is found to be optimal, where multiple morpheme-specific phonological requirements accumulate and co-trigger alternations within a single spell-out domain.
This paper brings novel data to bear on whether nominal concord relationships are formed in the narrow syntax or post-syntactically. In Guébie, a Kru language spoken in Côte d’Ivoire, nominal concord marking on non-human pronouns and adjectives is determined not by syntactic or semantic features of the concord-triggering noun, but by the phonological form of the noun. Specifically, concord marking on pronouns and adjectives surfaces as a vowel with the same backness features as the vowels of the head noun. Assuming that syntax is phonology-free (Pullum & Zwicky 1986, 1988), the fact that we see phonological features conditioning nominal concord in Guébie means that nominal concord must take place in the post-syntax. I expand on post-syntactic models of nominal concord in Distributed Morphology (Kramer 2010, Norris 2014, Baier 2015) showing that when combined with a constraint-based phonology, such an approach can account for both phonologically and syntactico-semantically determined concord systems. Additionally, the proposed analysis includes a formal account of ellipsis via constraints during the phonological component.
