Spatial Grammar And Simultaneity
Sign languages exploit the unique features of the visual medium , but may also exploit tactile features . Spoken language is by and large linear only one sound can be made or received at a time. Sign language, on the other hand, is visual and, hence, can use a simultaneous expression, although this is limited articulatorily and linguistically. Visual perception allows processing of simultaneous information.
One way in which many sign languages take advantage of the spatial nature of the language is through the use of classifiers. Classifiers allow a signer to spatially show a referent’s type, size, shape, movement, or extent.
The large focus on the possibility of simultaneity in sign languages in contrast to spoken languages is sometimes exaggerated, though. The use of two manual articulators is subject to motor constraints, resulting in a large extent of symmetry or signing with one articulator only. Further, sign languages, just like spoken languages, depend on linear sequencing of signs to form sentences the greater use of simultaneity is mostly seen in the morphology .
Where Did Asl Originate
No person or committee invented ASL. The exact beginnings of ASL are not clear, but some suggest that it arose more than 200 years ago from the intermixing of local sign languages and French Sign Language . Todays ASL includes some elements of LSF plus the original local sign languages over time, these have melded and changed into a rich, complex, and mature language. Modern ASL and modern LSF are distinct languages. While they still contain some similar signs, they can no longer be understood by each others users.
Teaching Country’s Sign Languages In Schools
Due to much exposure to sign language-interpreted announcements on national television, more schools and universities are expressing interest in incorporating sign language. In the US, enrolment for ASL classes as part of students’ choice of second language is on the rise. In New Zealand, one year after the passing of NZSL Act 2006 in parliament, a NZSL curriculum was released for schools to take NZSL as an optional subject. The curriculum and teaching materials were designed to target intermediate schools from Years 7 to 10, .

What Research Does The Nidcd Support On Asl And Other Sign Languages
The NIDCD supports research on ASL, including its acquisition and characterization. Funded research includes studies to understand sign languages grammar, acquisition, and development, and use of sign language when spoken language access is compromised by trauma or degenerative disease, or when speech is difficult to acquire due to early hearing loss or injury to the nervous system.

Study of sign language can also help scientists understand the neurobiology of language development. In one study, researchers reported that the building of complex phrases, whether signed or spoken, engaged the same brain areas. Better understanding of the neurobiology of language could provide a translational foundation for treating injury to the language system, for employing signs or gestures in therapy for children or adults, and for diagnosing language impairment in individuals who are deaf.
The NIDCD is also funding research on sign languages created among small communities of people with little to no outside influence. Emerging sign languages can be used to model the essential elements and organization of natural language and to learn about the complex interplay between natural human language abilities, language environment, and language learning outcomes.

Basics Of Alphabets And Fingerspelling
Most people start their sign language journey by learning the A-Z or alphabet equivalent in sign form.
The use of the hands to represent individual letters of a written alphabet is called fingerspelling. Its an important tool that helps signers manually spell out names of people, places and things that dont have an established sign.
For example, most sign languages have a specific sign for the word tree, but may not have a specific sign for oak, so o-a-k would be finger spelled to convey that specific meaning.
Of course, not every language uses the Latin alphabet like English, so their sign language alphabet differs as well. Some manual alphabets are one-handed, such as in ASL and French Sign Language, and others use two-hands, like BSL or Auslan. Though there are similarities between some of the different manual alphabets, each sign language has its own style and modifications, and remains unique.

Relationships With Spoken Languages
There is a common misconception that sign languages are somehow dependent on spoken languages: that they are spoken language expressed in signs, or that they were invented by hearing people. Similarities in language processing in the brain between signed and spoken languages further perpetuated this misconception. Hearing teachers in deaf schools, such as or Thomas Hopkins Gallaudet, are often incorrectly referred to as “inventors” of sign language. Instead, sign languages, like all natural languages, are developed by the people who use them, in this case, deaf people, who may have little or no knowledge of any spoken language.
As a sign language develops, it sometimes borrows elements from spoken languages, just as all languages borrow from other languages that they are in contact with. Sign languages vary in how much they borrow from spoken languages. In many sign languages, a manual alphabet may be used in signed communication to borrow a word from a spoken language, by spelling out the letters. This is most commonly used for proper names of people and places it is also used in some languages for concepts for which no sign is available at that moment, particularly if the people involved are to some extent bilingual in the spoken language. Fingerspelling can sometimes be a source of new signs, such as initialized signs, in which the handshape represents the first letter of a spoken word with the same meaning.
Sign Language Around The World: Irish Sign Language
Today, most people in Ireland speak English. But deaf people in Ireland speak Irish Sign Language , which is derived from French Sign Language. Although ISL has been somewhat influenced by BSL, it remains quite distinct. As of 2014, around 5,000 deaf people, primarily in the Republic of Ireland but also in Northern Ireland, use Irish Sign Language to communicate.
One interesting footnote about ISL: Many Irish deaf students were educated in Catholic schools that separated students by gender. So, for a time, men and women each had their own dialects of ISL. However, these differences have diminished over time.

Case And Number Agreement
Speakers of languages without grammatical case or adjectival agreement frequently complain about these aspects of Esperanto. In addition, in the past some people found the Classical Greek forms of the plural to be awkward, proposing instead that Italian -i be used for nouns, and that no plural be used for adjectives. These suggestions were adopted by the Ido reform.
Manual Codes For Spoken Languages
When Deaf and Hearing people interact, signing systems may be developed that use signs drawn from a natural sign language but used according to the grammar of the spoken language. In particular, when people devise one-for-one sign-for-word correspondences between spoken words and signs that represent them, the system that results is a manual code for a spoken language, rather than a natural sign language. Such systems may be invented in an attempt to help teach Deaf children the spoken language, and generally are not used outside an educational context.

Logical Visibility I: Visible Variables
We start our discussion of Logical Visibility with sign language loci, which were analyzed by several researchers as the overt manifestation of logical variables. It should be borne in mind that variables have played two slightly different roles in recent semantics. In the tradition of formal logic as well as in syntax and semantics, a quantifier can bind a variable only in case the latter is in its scope , or equivalently is c-commanded by it . Thus in a the variable x in P is semantically dependent on the universal quantifier x, but the second of occurrence of x, in Q, is not dependent on x because it is not in its scope. Exactly the same results hold of b modulo the replacement of the universal quantifier x with an existential quantifier x.
Sign Languages And Universal Grammar
As Sandler and Lillo-Martin write to introduce their ground-breaking survey ,
sign languages are conventional communication systems that arise spontaneously in all deaf communities. They are acquired during childhood through normal exposure without instruction. Sign languages effectively fulfill the same social and mental functions as spoken languages, and they can even be simultaneously interpreted into and from spoken languages in real time.
While our understanding of their history is often quite incomplete , the natural development of several recent sign languages has been documented in great detail by linguists and psycholinguists to mention but one prominent example, the development of Nicaraguan Sign Language has been traced through several generations of signers since its inception in the late 1970s . For our purposes, what matters is that sign languages have come to play an important role in studies of universals in phonology, morphology and syntax, for linguistic and neurological reasons.
Starting from the least linguistic approach, a major finding of neurological studies is that,
overwhelmingly, lesion and neuroimaging studies indicate that the neural systems supporting signed and spoken language are very similar: both involve a predominantly left-lateralised perisylvian network. Recent studies have also highlighted processing differences between languages in these different modalities.

Sign Languages And Universal Semantics
In what follows, we will take for granted the conclusions of recent linguistic research on the role of sign languages in studies of Universal Grammar, i.e. of the shared properties and parameters of variation found in the phonology, morphology and especially syntax of human languages. Universal Semantics can be similarly defined as the comparative study of interpretive processes in language, with the goal of determining which interpretive properties are universal and which are open to variation . Given the other similarities found between spoken and sign languages, it should go without saying that the latter have a role to play in studies of Universal Semantics. But we will argue that some properties of sign languages should give them a central role in foundational studies of semantics. Specifically, we will argue that sign languages can bring special insights into the foundations of semantics, for two reasons.
First, we will argue that sign languages can provide overt evidence on some key aspects of the logical structure of language, ones that one can only infer indirectly in spoken languages. We state this as a hypothesis of Logical Visibility in .
Hypothesis 1: Logical Visibility
Sign languages can make overt some mechanisms which have been posited in the analysis of the Logical Form of spoken language sentences, but are not morphologically realized in spoken languages.
A note might be in order about the history of these hypotheses.
Why Emphasize Early Language Learning
Parents should expose a deaf or hard-of-hearing child to language as soon as possible. The earlier a child is exposed to and begins to acquire language, the better that childs language, cognitive, and social development will become. Research suggests that the first few years of life are the most crucial to a childs development of language skills, and even the early months of life can be important for establishing successful communication with caregivers. Thanks to screening programs in place at almost all hospitals in the United States and its territories, newborn babies are tested for hearing before they leave the hospital. If a baby has hearing loss, this screening gives parents an opportunity to learn about communication options. Parents can then start their childs language learning process during this important early stage of development.

A Guide To The Different Types Of Sign Language Around The World
One of the most common misconceptions about sign language is that its the same wherever you go. Thats not the case. In fact, there are somewhere between 138 and 300 different types of sign language used throughout the world today. New sign languages frequently evolve amongst groups of deaf children and adults.
With that in mind, lets take a look at 9 examples of sign languages from around the world:
Achievement Of Its Creator’s Goals
One common criticism is that Esperanto has failed to live up to the hopes of its creator, who dreamed of it becoming a universal second language. Because people were reluctant to learn a new language which hardly anyone spoke, Zamenhof asked people to sign a promise to start learning Esperanto once ten million people made the same promise. He “was disappointed to receive only a thousand responses.”
However, Zamenhof had the goal to “enable the learner to make direct use of his knowledge with persons of any nationality, whether the language be universally accepted or not”, as he wrote in 1887. The language is currently spoken by people living in more than 100 countries there are about 2,000 native Esperanto speakers and probably up to 100,000 people who use the language regularly.
In this regard, Zamenhof was well aware that it might take much time for Esperanto to achieve his desired goals. In his speech at the 1907 World Esperanto Congress in Cambridge he said, “we hope that earlier or later, maybe after many centuries, on a neutral language foundation, understanding one another, the nations will build a big family circle.”
The poet Wisawa Szymborska expressed doubt that Esperanto could “produce works of lasting value” because it is “an artificial language without variety or dialects. No one thinks in Esperanto.”

Online Sign Language Dictionary Sites
Who uses a sign language dictionary? Think of the times you’ve watched someone giving a speech or lecture while, nearby, another person used rapid movements of hands, torso, and face to “sign” what the person speaking was saying. Their use of sign language allowed deaf or partially deaf people to “hear” right along with you and everyone else.
People who use signing to communicate with those who have hearing problems need ways to build their vocabulary or find just the “right” word. Of course, that makes them no different from the rest of us except for where they look to find the “words” they need.
If you’re one of them, you can find the words you need on the Internet, in a sign language dictionary.
A number of websites offer drawings, pictures, cartoons, books, and videos to help you learn the proper signs for particular words.
Aspect: Visible Event Decomposition
Cases of Visibility are not limited to the domains of reference and context-dependency . Wilbur argued that sign language makes visible the logical structure of verbs and coined the term Event Visibility to label her main hypothesis. To introduce it, a bit of background is needed. Semanticists traditionally classify event descriptions as telic if they apply to events that have a natural endpoint determined by that description, and they call them atelic otherwise. John spotted Mary and John built the house have such a natural endpoint the point at which John spotted Mary and completed the house, respectively John knew Mary and John danced lack such a natural endpoint and are thus atelic. As summarized in Rothstein , “the standard test for telicity is the use of temporal modification: in time modifies telic VPs and for time modifies atelic VPs as in “:

Language Endangerment And Extinction
As with any spoken language, sign languages are also vulnerable to becoming endangered. For example, a sign language used by a small community may be endangered and even abandoned as users shift to a sign language used by a larger community, as has happened with Hawai’i Sign Language, which is almost extinct except for a few elderly signers. Even nationally recognised sign languages can be endangered for example, New Zealand Sign Language is losing users. Methods are being developed to assess the language vitality of sign languages.

Notable Authors In Esperanto
In the futuristic novel Lord of the World by Robert Hugh Benson, Esperanto is presented as the predominant language of the world, much as Latin is the language of the Church. A reference to Esperanto appears in the science-fiction story War with the Newts by Karel apek, published in 1936. As part of a passage on what language the salamander-looking creatures with human cognitive ability should learn, it is noted that “…in the Reform schools, Esperanto was taught as the medium of communication.” .
Esperanto has been used in many films and novels. Typically, this is done either to add the exotic flavour of a foreign language without representing any particular ethnicity, or to avoid going to the trouble of inventing a new language. The Charlie Chaplin film The Great Dictator showed Jewish ghetto shop signs in Esperanto. Two full-length feature films have been produced with dialogue entirely in Esperanto: Angoroj, in 1964, and Incubus, a 1965 B-movie horror film which is also notable for starring William Shatner shortly before he began working on Star Trek. In Captain Fantastic there is a dialogue in Esperanto. The 1994 film Street Fighter contains Esperanto dialogue spoken by the character Sagat. Finally, Mexican film director Alfonso Cuarón has publicly shown his fascination for Esperanto, going as far as naming his film production company Esperanto Filmoj .
