What does monolingualism mean?
Being monolingual means knowing one language. Many people who grow up in Canada may be monolingual and know only English or French. In contrast, many Deaf Canadians may be bilingual because they use two or more languages, for instance, they might use ASL and the written form of English.
What does semilingualism mean?
In order to become fluently bilingual, with strong language skills in two languages, a child must have early access to a first language or “mother tongue”, preferably from birth. When children are given late, infrequent or inadequate exposure to two or more languages, they may become semilingual rather than bilingual. When a child is semilingual they seem to not have a full grasp of any language, and tend to mix the vocabulary, grammar and structure of the two languages together so that the child may not be fully able to express themselves in any language. In order to reap the benefits of being bilingual, a child must be given the opportunity to develop a strong first language.
What does semilingualism mean for Deaf children?
Since more than 90% of Deaf children are born into hearing families who may not know ASL, it is crucial for parents to make the extra effort so that Deaf children are exposed to a signed language (ASL) as early as possible in order to have a strong first language that is visual and 100% accessible. By being given frequent and consistent exposure to ASL through communication with family members, videos, and socializing with other Deaf children, a first language can develop which is the first step to developing strong language and critical thinking skills. By having ASL as a first language, it will be easier to acquire English because the child already has knowledge of language structure and has the ability to connect ideas. Without frequent exposure to ASL and with only limited access to English (since the child does not have full access to spoken English), the child is in danger of never fully acquiring either ASL or English and becoming semilingual. By making the effort to expose your child to ASL as frequently and as early as possible, your child can thrive and learn how to communicate in two languages- ASL and English.
