SUMMARY
Alexis Michaud's Tone in Yongning Na: Lexical tones and morphotonology
first appeared in 2017 and has since become a key reference for the
description of the tone system of Yongning Na (Mosuo), a Tibeto-Burman
language of Southwest China. This second edition (2025) retains the
core of the original — based on a decade of fieldwork (2006–2016), a
systematic treatment of lexical tones and morphotonological patterns,
and an autosegmental analytical framework — while incorporating
several substantial additions. These include two new chapters on
intonation (Chapters 8–9), a section addressing Mandarin-induced tone
loss (10.5), and an expanded ethnological appendix (B.3.4–B.3.5).
The empirical basis of the study is particularly noteworthy. The
analysis draws on long-term fieldwork, supplemented by follow-up
sessions in 2018 and 2024, and combines elicitation with corpus-based
observations. Michaud is explicit about consultant selection and
working practices, allowing readers to assess the evidential grounding
of the tonal analyses. This transparency contributes to the overall
reliability of the description.
The book proceeds from nouns and classifiers through compounds and
verbs to tone grouping rules (Chapters 1–7), before turning to
intonation (8–9), language attrition (10), areal comparison (11),
typological considerations (12), and a concluding chapter (13). One
particularly notable aspect is the treatment of floating H tones.
Michaud draws on comparative data from two neighbouring dialects,
Labai and Wujiao, where cognate morphemes carry an overt H tone. This
provides independent support for a tonal category that does not
surface in isolation in Alawua (2.3.3). Two appendices cover segmental
phonology and ethnohistorical background. Appendix B, in particular,
offers extensive discussion of Na ethnohistory, ethnic classification,
kinship systems, and the impact of tourism, alongside methodological
reflections on earlier survey data (B.3.1). Together, these additions
make the second edition a substantially expanded work relative to the
2017 original, particularly in its coverage of prosodic phonology and
language contact.
EVALUATION
1. Descriptive detail as documentation. A central contribution of the
volume lies in the level of descriptive detail. Rather than advancing
a strongly theory-driven agenda, the book provides a highly systematic
account of tonal contrasts, morphotonological patterns, and
exceptions. The empirical basis is unusually solid: data collection
spans a decade (2006–2016), with additional sessions in 2018 and 2024,
and the author is transparent about consultant selection and the
nature of the working relationship (1.4). For a language with limited
prior large-scale tonological description, this level of documentation
represents an important resource. This is particularly significant in
the context of language endangerment, where opportunities for
similarly extensive documentation may become increasingly limited.
The discussion of floating H tones in Chapter 2.3.3 illustrates this
approach well. Forms that surface with a level M tone in Alawua are
compared with corresponding H-tone syllables in the neighbouring Labai
and Wujiao dialects, offering comparative support for an underlying
tonal category that is not directly observable in isolation. In this
respect, the book joins a relatively small body of detailed,
book-length tonological descriptions of Tibeto-Burman languages — such
as Mazaudon (1977) on Tamang and Matisoff (1973) on Lahu — while
distinguishing itself through its systematic attention to
morphotonological rules and, in this second edition, to interactions
between tone and intonation. The level of detail provided — including
full paradigms and extensive examples from naturalistic texts — sets a
benchmark for future descriptive work on under-documented tonal
languages.
2. The intonation chapters. The addition of Chapters 8–9 addresses an
area that was less developed in the first edition. Chapter 8 surveys
theoretical issues in the study of intonation in tonal languages,
drawing on a range of cross-linguistic examples, while Chapter 9
applies these concepts to Yongning Na. The relationship between the
broader theoretical discussion and the Yongning Na data is at times
more implicit than explicit. Nevertheless, the descriptive
observations presented in Chapter 9 are valuable in their own right.
Michaud adopts a superpositional model in the tradition of Chao
Yuen-ren, treating intonation as a larger wave on which lexical tones
are superimposed as smaller ripples. This framework provides a way to
conceptualise how tone and intonation share the same phonetic channel
(fundamental frequency) while remaining functionally distinct. The
analytical contribution becomes clearer in Section 9.3.1, where two
less straightforward phenomena are examined in detail. In example
(10), emphatic stress transforms an underlying L.L.H tonal sequence
into surface L.H.L, suggesting that intonational effects may reshape
tonal patterns rather than simply overlay them. In the case of
extra-distal locatives (Table 9.1), the first syllable /dr/ is
realised with a rising or falling contour that does not map
straightforwardly onto a lexical tone category. Michaud tentatively
reconstructs an underlying L tone, while noting that the synchronic
data do not provide decisive evidence for a single tonal
representation. These observations provide a useful empirical basis
for further work on tone-intonation interaction. Given how rarely
tone-intonation interaction is examined in such depth for a
Tibeto-Burman language, this alone justifies the inclusion of the two
new chapters.
3. Cross-disciplinary contributions. Some of the most distinctive
aspects of the second edition emerge in areas that extend beyond core
tonal description. Section 10.5, which addresses Mandarin-induced tone
loss, documents processes such as tone category reduction,
simplification of morphotonological patterns, and partial realisation
of MH contours, with a level of phonological detail that will be of
interest to researchers working on language contact and sound change.
The discussion also provides a point of connection between detailed
phonological description and broader sociolinguistic processes.
Similarly, the expanded ethnological appendix (B.3.4–B.3.5) provides
updated material on kinship structures, social organisation, and the
impact of tourism. For researchers in language documentation, these
materials illustrate how detailed linguistic description can be
complemented by attention to the social and historical context in
which a language is embedded. These materials are presented outside
the main analytical chapters, in a dedicated section and in the
appendix. As noted by the author, this organisational choice reflects
considerations about scope and focus, including responses to earlier
feedback regarding the balance between tonal analysis and broader
contextual discussion. In a footnote at the start of Appendix B,
Michaud notes that earlier commentary suggested that extended
discussions of topics beyond the tonal system might affect the overall
balance of the volume, leading to their relocation.
The placement is therefore not incidental, and can be understood in
relation to broader disciplinary expectations about the scope of a
tonological description. As a result, readers interested in language
contact or ethnographic context will find substantial material,
although its integration with the core tonal analysis remains
relatively limited. Nevertheless, their presence signals a welcome
shift toward more contextually grounded language description, an
approach that remains all too rare in formal phonology.
4. Audience and scope. The book will be of particular relevance to
phonologists working on Tibeto-Burman languages or tonal systems more
broadly, for whom it provides a detailed descriptive reference for
Yongning Na. Researchers engaged in comparative or areal work will
find the tonal paradigms and morphotonological patterns a useful
source of data for cross-linguistic analysis. The volume will also be
of interest to scholars in language documentation and language
contact, especially in relation to the materials presented in Section
10.5 and Appendix B.
The analysis assumes familiarity with autosegmental phonology, and the
primary emphasis remains on detailed description rather than on the
development of new theoretical models. Within this scope, the second
edition represents a substantial development of the original volume.
It offers a careful and comprehensive empirical foundation that will
support future work on tonal systems. The volume is clearly organised,
with a functional index, an open-access online corpus, and extensive
cross-referencing between chapters. The availability of the online
corpus is a significant practical advantage, allowing other
researchers to verify and extend the analysis. The presentation of
tonal notation is consistent throughout, and the numerous example
tables, while occasionally dense, are clearly structured and
accessible with careful reading. For doctoral students and
early-career researchers, the book also serves as a methodologically
transparent model of how to conduct, document, and present field-based
tonal analysis.

ABOUT THE REVIEWER
The reviewer is a PhD candidate in Linguistics at Queen's University
Belfast, specialising in sociophonetics and Chinese dialectology.
Their research focuses on erhua (rhotacisation) variation in the
Beijing dialect, examining how phonetic variation is socially
conditioned in urban speech communities. This work involves extensive
sociolinguistic fieldwork, including the collection of interview data
from multiple speakers across different social groups and speech
styles. This background informs their interest in cross-speaker
variation and language contact phenomena, including the discussion of
Mandarin-induced tone loss in the present volume.
