Classifier constructions in sign languagesIn sign languages, the term classifier construction (also known as classifier predicates) refers to a morphological system that can express events and states. They use handshape classifiers to represent movement, location, and shape. Classifiers differ from signs in their morphology, namely in that signs consist of a single morpheme. Signs are composed of three meaningless phonological features: handshape, location, and movement. Classifiers, on the other hand, consist of many morphemes.
Grammatical numberIn linguistics, grammatical number is a feature of nouns, pronouns, adjectives and verb agreement that expresses count distinctions (such as "one", "two" or "three or more"). English and other languages present number categories of singular or plural, both of which are cited by using the hash sign (#) or by the numero signs "No." and "Nos." respectively. Some languages also have a dual, trial and paucal number or other arrangements.
British Sign LanguageBritish Sign Language (BSL) is a sign language used in the United Kingdom and is the first or preferred language among the deaf community in the UK. Based on the percentage of people who reported 'using British Sign Language at home' on the 2011 Scottish Census, the British Deaf Association estimates there are 151,000 BSL users in the UK, of whom 87,000 are Deaf. By contrast, in the 2011 England and Wales Census 15,000 people living in England and Wales reported themselves using BSL as their main language.
Hearing lossHearing loss is a partial or total inability to hear. Hearing loss may be present at birth or acquired at any time afterwards. Hearing loss may occur in one or both ears. In children, hearing problems can affect the ability to acquire spoken language, and in adults it can create difficulties with social interaction and at work. Hearing loss can be temporary or permanent. Hearing loss related to age usually affects both ears and is due to cochlear hair cell loss. In some people, particularly older people, hearing loss can result in loneliness.
Mutual intelligibilityIn linguistics, mutual intelligibility is a relationship between languages or dialects in which speakers of different but related varieties can readily understand each other without prior familiarity or special effort. It is sometimes used as an important criterion for distinguishing languages from dialects, although sociolinguistic factors are often also used. Intelligibility between languages can be asymmetric, with speakers of one understanding more of the other than speakers of the other understanding the first.
MultilingualismMultilingualism is the use of more than one language, either by an individual speaker or by a group of speakers. It is believed that multilingual speakers outnumber monolingual speakers in the world's population. More than half of all Europeans claim to speak at least one language other than their mother tongue; but many read and write in one language. Multilingualism is advantageous for people wanting to participate in trade, globalization and cultural openness.
Home signHome sign (or kitchen sign) is a gestural communication system, often invented spontaneously by a deaf child who lacks accessible linguistic input. Home sign systems often arise in families where a deaf child is raised by hearing parents and is isolated from the Deaf community. Because the deaf child does not receive signed or spoken language input, these children are referred to as linguistically isolated. Because home sign systems are used regularly as the child's form of communication, they develop to become more complex than simple gestures.
AuslanAuslan (ˈɒzlæn) is the sign language used by the majority of the Australian Deaf community. The term Auslan is a portmanteau of "Australian Sign Language", coined by Trevor Johnston in the 1980s, although the language itself is much older. Auslan is related to British Sign Language (BSL) and New Zealand Sign Language (NZSL); the three have descended from the same parent language, and together comprise the BANZSL language family. Auslan has also been influenced by Irish Sign Language (ISL) and more recently has borrowed signs from American Sign Language (ASL).
IconicityIn functional-cognitive linguistics, as well as in semiotics, iconicity is the conceived similarity or analogy between the form of a sign (linguistic or otherwise) and its meaning, as opposed to arbitrariness (which is typically assumed in structuralist, formalist and generative approaches to linguistics). The principle of iconicity is also shared by the approach of linguistic typology.
