Inflection Classes in Verbs in the Romance Languages

Author(s):  
Marc-Olivier Hinzelin

The Romance languages inherited from Latin a system of four inflection classes in verbs featuring a dedicated theme vowel (or its absence). The presence of the theme vowel in inflectional forms differs from language to language and from inflection class to inflection class. In Latin, the theme vowels are found in most forms; in Romance, their presence has declined but they are still featured at least in the infinitive of most inflection classes. Most Romance languages simplified the Latin system by reducing the number of inflection classes while retaining the class distinction by theme vowels. In many Romance languages, new inflection classes have evolved. The existence of verbs with a stem-forming augment is often described as a subclass in traditional grammars. But the augment appears in a well-defined set of paradigm cells warranting the introduction of a new class. In a synchronic analysis, French and Oïl varieties show mostly a distinction based on length of the stem or, from another perspective, pattern of syncretism as many forms are homophonous. This is partly due to the fact that some very frequent forms do not feature any longer inflectional suffixes in their phonetic realization (although these are retained in spelling). New irregularities in the stem found in all Romance languages suggest the emergence of an additional class distinction based on the form, number, and distribution of the stems. Morphomic patterns arose which may be interpreted as inflection classes. The most radical change took place in French: Some analyses claim that none of the traditional classes distinguished by theme vowels survives; only stem distinctions may be used to establish inflection classes. Other studies still assume theme vowels in French, at least with verbs ending in -ir in the infinitive. Suppletion or other processes may lead to heteroclisis (i.e., forms of the same verb pertaining to different inflection classes).

We draw on ‘new’ class analysis to argue that mockery frames many cultural representations of class and move to consider how it operates within the processes of class distinction. Influenced by theories of disparagement humour, we explore how mockery creates spaces of enunciation, which serve, when inhabited by the middle class, particular articulations of distinction from the white, working class. From there we argue that these spaces, often presented as those of humour and fun, simultaneously generate for the middle class a certain distancing from those articulations. The plays of articulation and distancing, we suggest, allow a more palatable, morally sensitive form of distinction-work for the middle-class subject than can be offered by blunt expressions of disgust currently argued by some ‘new’ class theorising. We will claim that mockery offers a certain strategic orientation to class and to distinction work before finishing with a detailed reading of two Neds comic strips to illustrate what aspects of perceived white, working class lives are deemed appropriate for these functions of mockery. The Neds, are the latest comic-strip family launched by the publishers of children's comics The Beano and The Dandy, D C Thomson and Co Ltd.

Neurolinguistics is devoted to the study of the language-brain relationship, using the methodologies of neuropsychology and cognitive neuroscience to investigate how linguistic categories are grounded in the brain. Although the brain infrastructure for language is invariable across cultures, neural networks might operate differently depending on language-specific features. In this respect, neurolinguistic research on the Romance languages, mostly French, Italian, and Spanish, proved key to progress the field, especially with specific reference to how the neural infrastructure for language works in the case of more richly inflected systems than English. Among the most popular domains of investigation are agreement patterns, where studies on Spanish and Italian showed that agreement across features and domains (e.g., number or gender agreement) engages partially different neural substrates. Also, studies measuring the electrophysiological response suggested that agreement processing is a composite mechanism involving different temporal steps. Another domain is the noun-verb distinction, where studies on the Romance languages indicated that the brain is more sensitive to the greater morphosyntactic engagement of verbs compared with nouns rather than to the grammatical class distinction per se. Concerning language disorders, the Romance languages shed new light on inflectional errors in aphasic speakers and contributed to revise the notion of agrammatism, which is not simply omission of morphemes but might involve incorrect substitution from the inflectional paradigm. Also, research in the Romance domain showed variation in degree and pattern of reading impairments due to language-specific segmental and suprasegmental features. Despite these important contributions, the Romance family, with its multitude of languages and dialects and a richly documented diachronic evolution, is a still underutilized ‘treasure house’ for neurolinguistic research, with significant room for investigations exploring the brain signatures of language variation in time and space and refining the linking between linguistic categories and neurobiological primitives.

Porous semiconductors represent a relatively new class of materials formed by the selective etching of a single or polycrystalline substrate. Although porous silicon has received considerable attention due to its novel optical properties1, porous layers can be formed in other semiconductors such as GaAs and GaP. These materials are characterised by very high surface area and by electrical, optical and chemical properties that may differ considerably from bulk. The properties depend on the pore morphology, which can be controlled by adjusting the processing conditions and the dopant concentration. A number of novel structures can be fabricated using selective etching. For example, self-supporting membranes can be made by growing pores through a wafer, films with modulated pore structure can be fabricated by varying the applied potential during growth, composite structures can be prepared by depositing a second phase into the pores and silicon-on-insulator structures can be formed by oxidising a buried porous layer. In all these applications the ability to grow nanostructures controllably is critical.

In neurons, the microtubule associated protein, tau, is found in the axons. Tau stabilizes the microtubules required for neurotransmitter transport to the axonal terminal. Since tau has been found in both Alzheimer neurofibrillary tangles (NFT) and in paired helical filaments (PHF), the study of tau's normal structure had to preceed TEM studies of NFT and PHF. The structure of tau was first studied by ultracentrifugation. This work suggested that it was a rod shaped molecule with an axial ratio of 20:1. More recently, paraciystals of phosphorylated and nonphosphoiylated tau have been reported. Phosphorylated tau was 90-95 nm in length and 3-6 nm in diameter where as nonphosphorylated tau was 69-75 nm in length. A shorter length of 30 nm was reported for undamaged tau indicating that it is an extremely flexible molecule. Tau was also studied in relation to microtubules, and its length was found to be 56.1±14.1 nm.

Recently there has been much excitement over a new class of high Tc (>30 K) ceramic superconductors of the form A1-xBxCuO4-x, where A is a rare earth and B is from Group II. Unfortunately these materials have only been able to support small transport current densities 1-10 A/cm2. It is very desirable to increase these values by 2 to 3 orders of magnitude for useful high field applications. The reason for these small transport currents is as yet unknown. Evidence has, however, been presented for superconducting clusters on a 50-100 nm scale and on a 1-3 μm scale. We therefore planned a detailed TEM and STEM microanalysis study in order to see whether any evidence for the clusters could be seen.A La1.8Sr0.2Cu04 pellet was cut into 1 mm thick slices from which 3 mm discs were cut. The discs were subsequently mechanically ground to 100 μm total thickness and dimpled to 20 μm thickness at the center.

Conducting polymers comprises a new class of materials achieving electrical conductivities which rival those of the best metals. The parent compounds (conjugated polymers) are quasi-one-dimensional semiconductors. These polymers can be doped by electron acceptors or electron donors. The prototype of these materials is polyacetylene (PA). There are various other conjugated polymers such as polyparaphenylene, polyphenylenevinylene, polypoyrrole or polythiophene. The doped systems, i.e. the conducting polymers, have intersting potential technological applications such as replacement of conventional metals in electronic shielding and antistatic equipment, rechargable batteries, and flexible light emitting diodes.Although these systems have been investigated almost 20 years, the electronic structure of the doped metallic systems is not clear and even the reason for the gap in undoped semiconducting systems is under discussion.
