Abstract:
We examined the production of the Irish initial mutation eclipsis in two speaking styles. In initial mutation phenomena, a word appears with a different initial sound depending on the lexical or morphosyntactic environment (e.g.croí[kɾɣi] ‘(a) heart’ (radical form), (a)chroí[xɾɣi] ‘(his) heart/darling’ (séimhiú-lenition form), and (a)gcroí[ɡɾɣi] ‘their heart/darling’ (eclipsis form)). The goals of the study were:(i)to examine whether there are acoustic differences between the initial consonants of radical word forms (e.g. [ɡ] ofgruig‘(a) frown/scowl’) and the corresponding consonants of eclipsis forms (e.g. [ɡ] ofgcroí), as has been found for similar phenomena in other languages;(ii)to examine variability in the patterns of initial mutation in the speech of present-day speakers of Irish.Our analyses offer limited evidence that there may be phonetic differences between radical and corresponding eclipsis consonants, but the current data do not allow us to rule out alternative explanations. The realization of initial mutations in semi-spontaneous speech differed dramatically both from that of read speech and from the expectations of the traditional grammar. The results suggest that the realization of eclipsis and other initial mutations may be style- or register-dependent. We also found some evidence that it may vary by consonant type, in part due to phonological frequency patterns of the language.

Abstract:
This article offers a unified syntactic treatment of initial mutation in Modern Irish, one of the best-known characteristics of that language. Both types of consonant mutation, as well as the less-studied mutations affecting vowels, are discussed. It is proposed that the appearance of initial mutation is a function of particular structural configurations: mutation is triggered by lexicalized functional heads. It is shown how this analysis applies in three syntactic contexts: before clausal predicates; within noun phrases; and following prepositions. Special attention is given to the problem raised by exceptional forms, and, in particular, to the problem of variable constraints on “spreading” (whereby mutation spreads to following modifiers only in certain instances).

Abstract:
One of the most important insights of Optimality Theory (Prince & Smolensky 1993) is that phonological processes can be reduced to the interaction between faithfulness and universal markedness principles. In the most constrained version of the theory, all phonological processes should be thus reducible. This hypothesis is tested by alternations that appear to be phonological but in which universal markedness principles appear to play no role. If we are to pursue the claim that all phonological processes depend on the interaction of faithfulness and markedness, then processes that are not dependent on markedness must lie outside phonology. In this paper I will examine a group of such processes, the initial consonant mutations of the Celtic languages, and argue that they belong entirely to the morphology of the languages, not the phonology.

Abstract:
This paper questions the voiceless-voiced distinction of Welsh consonants and claims that the fortis-lenis distinction is more appropriate for the description of the language. In light of research results of theoretical as well as experimental investigations into Welsh, e.g. the vowel-coda length dependence discovered by Asmus and Grawunder (2017), advocated further research into that matter, seeing also that the fortis-lenis distinction establishes a firm link to focal properties of Welsh, such as morpheme-initial consonant mutations (mICM). It was, therefore, decided to look at potential phonetic features that would contribute to the postulated distinction. These features are aspiration, voicing, hold phase duration and the centre of gravity (abbreviated to CoG) in the articulation of Welsh plosives. Preliminary results of the study discussed in this paper were summarised in “Fortis-lenis or Voiced-voiceless – features of Welsh consonants” (Asmus et al. 2019). However, expanding our research has yielded more comprehensive findings. As a result, it appears that the two series of plosives under review are different in terms of all features studied, but it is aspiration that is of major importance (thus confirming classifications of Welsh as an aspiration language).

Abstract:
Listeners integrate a wide variety of cues when categorizing speech sounds, including lexical, syntactic, semantic and pragmatic information. We investigate the influence of Initial Consonant Mutation, a morphosyntactically-triggered alternation in the modern Celtic languages, on the categorical perception of stop voicing in Welsh. Once sandhi processes, Celtic mutations are now lexically and morphosyntactically triggered; in particular, Welsh Soft Mutation causes word-initial voiceless stops to become voiced when they are preceded by a triggering word or construction. This paper reports the results of a two-alternative forced choice task that tests the hypothesis that Welsh listeners integrate their knowledge of mutation-triggering environments during speech perception, accepting more ambiguous segments as voiced when preceded by a Soft-Mutation-triggering word relative to a non-triggering word. While the results of the experiment demonstrate categorical perception of stop voicing, no robust effect of mutation environment was found. Several hypotheses as to why the predicted result was not found are considered.

Full text
Abstract:
In this paper I argue that initial consonant mutation in the Celtic languages does not involve synchronically derived phonological alternation, nor is it the product of full lexical listing of alternant wordforms. Rather, Celtic initial mutation involves associations of consonants represented in the lexicon which relate a specific initial consonant of a radical form to its associated mutation reflexes. Together with subcategorisation, which ensures that the correct mutation reflex of a wordform appears in the correct environment, the appropriate initial consonant is selected from an association of consonants extracted by the speaker from the recurring patterns in the language. It is these consonant associations, not full alternant wordforms, that are listed in the lexicon. The advantages to this approach are threefold: broad patterns are identified which full lexical listing obscures, the participation of neologisms in mutation is accounted for straightforwardly, and some of the motivation for diachronic reanalysis within the mutation system is made more apparent.

Abstract:
Abstract Background: Thyroid dysgenesis is the most frequent cause of congenital hypothyroidism (CH), and its genetic basis is largely unknown. Hitherto, two mutations in the human thyroid transcription factor 2 (TTF-2) gene have been described in unrelated cases of CH with cleft palate, spiky hair, variable choanal atresia, and complete thyroid agenesis. Here, we describe a novel TTF-2 mutation in a female child resulting in syndromic CH in the absence of thyroid agenesis. Results: The index case is homozygous for an arginine to cysteine mutation (R102C) of a highly conserved residue within the forkhead, DNA binding domain of TTF-2. Her consanguineous, heterozygous parents are unaffected, and the mutation was not detected in 100 control chromosomes. Consonant with its location, the R102C mutant TTF-2 protein showed loss of DNA binding and was transcriptionally inactive. CH in the proposita was associated with cleft palate, spiky hair, and bilateral choanal atresia. However, radiological studies showed the presence of thyroid tissue in a eutopic location. Conclusion: Our findings indicate that human thyroid development can occur despite loss of TTF-2 function and suggest that TTF-2 gene defects should also be considered in cases of syndromic CH without total athyreosis.

Abstract:
6028 Background: Abnormalities in EGFR signaling targets are associated with C resistance but no biomarker of C resistance has been identified in HNSCC. We hypothesized that cases with loss of PTEN protein expression (PTEN null) or PIK3CA mutation would display C resistance in HNSCC. Methods: E5397 was a phase III trial of CDDP plus P or CDDP plus C and enrolled 117 eligible and evaluable pts. PIK3CA and PTEN were analyzed for 52 and 67 consented pts, respectively. PTEN expression (PTEN Cell Signaling Technology, Cat. 9559) was determined by automated quantitative analysis (AQUA) on the PM-2000 (HistoRx, New Haven) using a cutpoint generated in 5 HNSCC tissue microarrays, each consisting of HNSCC as well as positive (small intestine, median AQUA score 2833.2) and negative controls (breast and colon carcinoma, median AQUA score 205.5). A cutpoint of 570 provides 100% specificity, 100% sensitivity, and identified 30% of the HNSCCs as PTEN null, consonant with the literature. The 3 most common PIK3CA mutations (E542K and E545K in exon 9 and H1047R in exon 20) were determined by BEAMing (Inostics, Heidelberg, Germany). Response, overall survival (OS) and progression-free survival (PFS) were compared between PTEN null or PIK3CA mutated pts and all others. Log rank and multivariable Cox proportional hazards modeling were used to calculate p values. Results: 23/67 (34%) tumors were PTEN null and 2/52 (4%) had PIK3CA mutations (E542K and E545K). Both tumors with PIK3CA mutation had PTEN expression. No statistically significant differences in response, OS or PFS were noted in this small sample. However, among PTEN expressing/PIK3CA WT pts, median PFS increased to 4.2 months (m) for C (N=22) from 2.9 m for P (N=26) (Wald p=0.07), compared with 4.6 m for C (N=12) and 3.5 m for P (n=13) among the PTEN null/PIK3CA mutated (Wald p=0.60). Conclusions: The PTEN loss or PIK3CA mutation signature warrants further investigation as a predictor of C resistance.

Abstract:
This thesis produces a definition of consonant mutations, a hitherto relatively unexplored phenomenon in typology, using a sample of languages from the Celtic and Uralic languages. It is defined using Canonical Typology. The base of the phenomenon is established as ‘functionalized consonant alternations’, with seven dimensions of variation: conditioning elements>no conditioning elements; sole functional indicator>accompanied by other morphemes; more than two grades>two grades; some effect on surrounding vowels>only affecting the consonant; only leniting>also non-leniting sound changes; word-initial/-final>word-medial placement; and less regular>more regular. It is also argued that mutations’ phonology is less important than their function.

Thesis advisor: Michael J. Connolly
The Insular Celtic languages, such as Irish and Welsh, distinctively feature a morphophonemic process known as initial consonant mutation. Essentially the initial sound of a word changes due to certain grammatical contexts. Thus the word for 'car' may appear as carr, charr and gcarr in Irish and as car, gar, char and nghar in Welsh. Originally these mutations result from assimilatory phonological processes which have become grammaticalized and can convey morphological, semantic and syntactic information. This paper looks at the primary mutations in Irish and Welsh, showing the phonological changes involved and exemplifying their basic triggers with forms from the modern languages. Then it explores various topics related to initial consonant mutations including their historical development and impact on the grammatical structure of the Celtic languages. This examination helps to clarify the existence and operations of the initial mutations and displays how small sound changes can have a profound impact upon a language over time

Abstract:
Cette étude apporte un nouveau corpus à la description du paysage linguistique de Basse-Bretagne et participe de ce fait à une meilleure connaissance de la langue bretonne dans son ensemble. Les habitudes langagières constatées dans ce parler haut-vannetais seront décrites à partir d'exemples issus de langue parlée, et de langue chantée, collectés auprès de vingt-cinq locuteurs traditionnels originaires de Languidic, nés entre 1919 et 1950. Après avoir défini le terroir dialectal de ce breton, haut vannetais intérieur de transition, nous présentons son système vocalique, qui est un élément distinctif entre les parlers de ce sous-dialecte. Nous verrons quele timbre des voyelles peut être centralisé ou neutralisé selon leur quantité, qui est elle-même dépendante de celles des consonnes. Le système consonantique sera défini et exposé en tenant compte de la typologie du breton, étant une langue à mutations consonantiques. Le schéma accentuel, bien que principalement oxytonique, présente de nombreuses variations. Les mutations consonantiques des initiales s'organisent en trois principaux groupes, s'associant pour certains mutateurs, créant ainsi trois types de mutations hybrides, auxquels il faut ajouter trois mutations isolées. La morphologie et la syntaxe du parler sont exposées et tenant compte des différents usages, allant du registre familier quotidien, à la langue soutenue des chants, qui sont une des richesses de ce terroir, où les traditions orales ont su se maintenir jusqu'à nos jours
This work presents a new study of work to the visual description of dialectology in the lower region of Brittany and participates in providing a better understanding of the Breton language in its entirety.The usages and customs of this micro-dialect from this part of Brittany known as haut-vannetais will be described from examples of spoken language and song. These are collected from twenty five traditional native speakers originally from Languidic, born between 1919 and 1950. After having defined the dialect area of this local speech, haut-vannetais in transition, we present its vocalic system, which in itself is a distinct element between different spoken sub dialects. We will see that the tone of vowels could be centralised or neutralised depending on their quantity. This also applies for the consonants. The consonantal system will be defined and exposed by considering the typology of Breton, with initial consonant mutations. The lexical stress, which is principally oxytonic presents numerous variations. There are three principal classes of mutation, three hybrid and three isolated mutations. The morphology and syntax of this sub dialect is exposed in consideration of different usages, ranging from familiar everyday language to received pronunciation used whilst singing, which give a richness to the region where the oral traditions have been retaineduntil today

This chapter discusses the consonant phoneme inventory, briefly comparing the Chichewa consonant inventory with that of Proto-Bantu, before turning to the distribution of the consonants in different morphologically defined positions (stem-initial, stem-medial, affixes). The second half of the chapter surveys the main consonantal phonological processes. The processes discussed include regular and productive processes, like nasal place assimilation and postnasal stop aspiration, and morphologically conditioned consonant mutations involved in the formation of noun class 5/6 singular–plural pairs and in the formation of causative verbs.

Abstract:
Old Irish is a notoriously difficult language, and the chapter begins with an account of why this is so, exploring the features such as consonant mutations, palatalization, the absolute and conjunct inflections of verbs, conjugated prepositions, verb-initial sentences, and infixed pronouns that make it so distinct from the other languages considered so far. But even so, it is still of Indo-European stock, and a couple of selections from the Táin Bó Cuailnge reveal some of this shared ancestry. The chapter also offers an extended comparison with Welsh, another important member of the Celtic branch, highlighting, with an excerpt from the Mabinogion, the Celtic features common to it and Irish, as well as the points of difference between the two.
