Abstract

Current phasal models of words differ from one another in two main ways: which heads are phasal and whether a phase head allows higher heads to access its complement. Through an investigation of verbs in Muskogee, this paper argues that in some languages, words have functional phase heads that divide them into two domains and that block all higher heads from access to morphemes. Specifically, Muskogee verbs contain aspectual phase heads (Asp0), which separate the verb into a sub-aspectual, VP-level domain—Phase One (Φ1)—and a superaspectual, InflP-level domain—Phase Two (Φ2). As previous work on Muskogee has shown, Φ1 (the ‘Stem’ in previous literature) and Φ2 form separate domains both in phonology, affecting stress and tone patterns, and in temporal semantics. This paper makes the novel observation that morphemes in Φ1 and Φ2 do not interact with each other in rules of allomorphy or allosemy, despite widespread interaction within each domain. An Asp0 phase head that follows the strong PIC1 accounts for the lack of interaction between Φ1 and Φ2. Categorizers, which are typically taken to be phase heads, behave differently from Asp0 in Muskogee, though their phasal status is unclear.

Notes

  1. Muskogee, also known as ‘Maskoke,’ ‘Creek,’ and ‘Seminole,’ is a member of the Muskogean language family spoken in the southern United States, originally in the current states of Alabama and Georgia. Muskogee is spoken in three different communities: by around 3,000 people in the Muscogee (Creek) Nation in Oklahoma, about 700 in the Seminole Nation of Oklahoma, and about 200 in the Seminole Tribe of Florida (Martin 2011:17; numbers estimated from 2000, so may be different now). In the latter two communities, the dialects are known as “Oklahoma Seminole Creek” and “Florida Seminole Creek,” respectively.

  2. Most of the data in this paper come from the Creek (Muskogee) Grammar, by Jack Martin with speakers Margaret McKane Mauldin and Juanita McGirt (cited as Martin 2011). Other data come from Hardy’s (1988) dissertation, Muskogee narratives in Gouge (2004), (Kimberly) Johnson’s (2018, 2019) work on Muskogee syntax and semantics, and personal communication with both Martin and Johnson. This paper is informed by Haas’ (1940, 1977) descriptive work on Muskogee morphology, temporal semantics and prosody, Nathan’s (1977) grammar of Florida Seminole Creek, Hardy’s (1988) investigation of verbal morphosyntax and semantics in Muskogee, Martin’s (1991) study of argument structure and transitivity, Martin and (Keith) Johnson’s (2002) acoustic study of prosody, and Martin’s (2010) and Johnson’s (2019) investigations of tense. This work is a revision and extension of the analysis of Muskogee in Guekguezian (2017:Sect. 3). Any sources of empirical disagreement are noted.

  3. Muskogee also has periphrastic constructions using a main verb and an auxiliary verb, the most common of which is ‘be’ (/ooM/ in Hardy 1988, /om/ in Martin 2011: Sect. 32). The auxiliary ‘be’ /ooM, o:m/ has the effect of backgrounding the main verb (Hardy 1988:336) or asserting information (Martin 2011:300–301); it also has evidential uses (Johnson 2019). Other auxiliaries “express[] modality, evidentiality, or aspect” (Martin 2011:298).

    The position of auxiliaries in the clausal structure requires more research. On the one hand, both the main verb and auxiliary verb have autosegmental morphology encoding aspect, which can be the same or different between the two verbs (Martin 2011:300). This suggests that auxiliary constructions are biclausal, with separate VP projections, as suggested by one reviewer. On the other hand, some Φ2 suffixes appear on the main verb and others on the auxiliary verb (Martin 2011:301–302). This suggests that the main verb and the auxiliary are in the same clause, with the auxiliary moving up into IP, as another reviewer suggests. The morphosyntax of auxiliaries is outside of the scope of this paper.

  4. Thanks to Daniel Harbour for suggesting the term “allotypy”.

  5. This Agr head is likely distinct from the patient agreement prefixes in Φ1 that agree with speech participant for person and number: /ca-/ 1st.sg, /po-/ 1st.pl, and /ci-/ 2nd (Martin 2011:168–170). These patient agreement prefixes may spell out either a separate Agr head or an pronominal argument in a specifier slot.

  6. Tables 1012 do not give full Muskogee verbs, but only the exponents of the root, transitivity, and number agreement (all taken from Martin 2011:Sects. 23–24); a complete verb requires aspect morphology (including /Ø/ irr) and an overt mood suffix (in matrix clauses) or switch-reference clitic (in embedded clauses).

  7. If, on the other hand, the examples in (38) are cases of allotypic interaction, Asp0 can still be a phase head if /-ip/ spontaneous is included in the Asp projection. /-ip/ provides aspectual semantics and sits at the right edge of the Φ1 domain (Martin 2011, though cf. Hardy 1988). If /-ip/ is adjoined to Asp, in its specifier, or the exponent of a feature on Asp, /-ip/ would be phase-accessible to both Φ1 and Φ2 morphemes, similarly to Asp0 itself. While /-ip/ is clearly in the first phonological domain as defined by footing and tone (Sect. 3.1), this does not necessarily mean that /-ip/ cannot be in the Asp projection. For example, in Bošković’s (2016) proposal, PF domains contain the phase heads themselves, so that material in the Asp projection would sit in the first phonological domain (though see Sect. 5.2 for evidence that Asp morphology’s position in the first phonological domain is compatible with being spelled out at the second phase). The same account may work for /-aha:n/ prospective, which is similar to /-ip/ in position and aspectual semantics.

  8. Similar conditions may obtain on the LF side if Martin is correct that /Ø/ (‘Zero-grade’) is a default form used when other, semantically contentful aspects are not appropriate (I have instead adopted Hardy’s (1988) proposal that /Ø/ Asp0 encodes irrealis). Under Martin’s analysis, /Ø/ Asp0 should not prevent linear adjacency for semantics, so Φ1–Φ2 allosemic interaction should be likely across /Ø/ Asp0. Allosemic interaction does occur between morphemes that are separated by agreement morphology. For example, in (i), the root ‘go’ has the alloseme ‘take’ in the context of /is-/ instrumental and /-y/ direct causative. In (i), the agreement markers /ac-/ and /-ho/ interrupt linear adjacency between the root /a/ ‘go’ and both /is-/ and /-y/, respectively.

    Allosemy also occurs across agent agreement in Φ2: the Φ2 head durative has an ability meaning in the context of eventive aspect, no matter whether agreement intervenes (Martin 2011:249–251, 305). As an anonymous reviewer points out, agreement morphology does not affect the truth conditions and may be ignored at LF for purposes of linear adjacency (Marantz 2013; see Rice 2000 for Athabaskan).

  9. An initially plausible argument against categorizers being phasal in Muskogee is that Φ1 morphemes above v interact with the root. As demonstrated in Sect. 3.1, Muskogee verbs exhibit considerable allomorphic interaction among the root and both transitivity and number agreement suffixes, which depend on the other two morphemes for VI insertion ((17)–(24), Tables 1012). Under the assumption that only one of the two suffixes is v, the other suffix must be above v and should not be able to access the root if v were a phase head following PIC1. Moreover, other Φ1 morphemes trigger allosemy selection with the root, including the reciprocal, instrumental, and several locative prefixes ((26) above). These morphemes are higher than the categorizer v, so v does not block access to the root.

    However, as multiple reviewers point out, there are several problems with this line of argumentation. First, if the root head-adjoins to its categorizer (following, e.g., Marantz 2013; Kastner 2016), it would not be the complement of v, and thus not be rendered inaccessible to other Φ1 morphemes by PIC1. Second, v may be null and the two overt suffixes higher: number agreement in AgrPat and transitivity in Voice. Since v is null, it would not block interaction between the root, Agr and Voice (see, e.g., Embick 2010, 2013, Marantz 2013 for interaction across null categorizers). Alternatively, number agreement may be a selectional feature on either the root or v, so that it is adjacent to both. Node-sprouting (Choi and Harley 2019) would then occur in the postsyntax so that the suffix can be inserted.

  10. With verbal nouns in /-ka/, the direct causative suffix /y/ is dropped. For example, in (49c), the typical allomorph of v/VoiceDC used with the root /itipo/ ‘fight’, /y/, is not present (though Martin 2011 does not say so, it seems possible that the Φ1 /itipo-y/ contains /iti-/ reflexive). While Martin takes /y/ to be an allomorph of v/VoiceDC, Hardy gives it as a “morphophoneme variant conditioned by a following vowel” when the root (+ Agr) ends in a vowel. Almost all following suffixes begin in a vowel, so that /y/ is almost always present in such cases. Other allomorphs of v/VoiceDC, like /ic/ in (49a), are present with /-ka/, which thus cannot attach, below v/Voice. On Martin’s analysis, /y/ is deleted (or /Ø/ is inserted) in the context of /-ka/, while on Hardy’s analysis /y/ is inserted in the context of other morphemes (or in the context of following vowels). Alternatively, /y/’s appearance is governed by context-dependent readjustment rules. Since on a categorizing phase analysis, both v and n are phase heads, the allomorphic interaction between /-ka/ gerundive and /-y/ v/VoiceDC is allowed by the Activity Corollary (Embick 2013:6).

  11. There are two possible counterarguments to there being an Asp0 phase head in agentive nominalizations. First, Martin gives glosses of agentive nominalizations with specialized meanings, like [famí:c-a] ‘muskmelon, cantaloupe’ from /famic/ ‘scented’ (2011:108). These are likely not cases of allosemy, but instead conventionalized specializations of the agentive’s basic meaning of “one who does/is X all the time.” E.g., [fami:c-a] may mean “one that smells all the time,” but be restricted in actual usage to the stinky fruit. See Marantz (2013:105–106) for the distinction between allosemy, which must be phase-local, and special or idiomatic meanings, which do not have to be.

    Second, Martin states that agentive nominalizations have a single phonological domain: “agent nominalizations are accented like nouns. ‘Long’ verbs in the lengthened grade generally have two accents (opóna:y-ís ‘he/she is speaking’), but agent nominalizations do not (oponá:y-a ‘speaker’)” (2011:108). However, independent phonological considerations may rule out two accents in agentive nominalizations, such as clash avoidance *[(o.pó).(ná:).ya)] or the final light syllable, which cannot be footed by itself *[(o.pó).(na:).(yá)]. Because agentives always consist of a Φ1 domain with a final heavy syllable and are followed by the single, light vowel [-a], it is unclear whether these forms have one or two phonological domains. This applies to all agentive nominalizations as far as I am aware, not only agentives where the Φ1 domain has the same shape as /oponay/.

I would like to acknowledge the following people who have supported and improved the work in this paper. Jack Martin has graciously provided detailed answers to my numerous questions about the phonology and morphology of Muskogee verbs over the past few years. Moreover, without Jack’s decades of fieldwork on Muskogee and subsequent grammar, this paper would not have been possible. I also thank Kimberly Johnson both for discussion of her own fieldwork on Muskogee and for her insights into Muskogee morphosyntax and semantics. I am indebted to the other linguists who have worked on Muskogee over the last several decades, especially Mary Haas and Donald Hardy, and of course their Muskogee language consultants, without whom neither their work nor mine would be possible.

My postdoctoral adviser at University of Rochester, Joyce McDonough, has provided extensive and constructive feedback on my examination of morphological constituency in Muskogee. Joyce has consistently kept me focused on finding empirical generalizations in the data. The entire Department of Linguistics and Center for Language Sciences at the University of Rochester has supported and influenced my work on Muskogee over the last two years. Solveiga Armoškaitė and Katy McKinney-Bock have both pored over drafts of this work at different stages; their cogent critiques have vastly improved both my account and my exposition. Hossep Dolatian has also offered helpful ideas that have benefited this paper. I further appreciate the feedback on earlier stages of this work by my dissertation committee at the University of Southern California: my adviser, Karen Jesney, and my other committee members, Rachel Walker, Roumyana Pancheva, Maria Luisa Zubizarreta, and Mario Saltarelli.
