1. How do you use language in your life?
When we start thinking about what defines us as human beings, and we ask people around us that question, most likely among the first answers that we will get is going to be language or languages. The ability to learn and use languages is our most prized human ability. It probably played a decisive role in our evolving as a species. Also unique, and very useful, is our ability to learn a second language, a third language, a fourth language. Not our mother tongue that we grew up speaking.
Not just lingualism, which would be the ability to acquire and use a language, but multilingualism, the ability to learn and use many languages throughout our lifetime, is another fundamental dimension of the human condition. Indeed, available data indicate that there are more bilinguals in this world than monolingual individuals.
What do we know when we know language?
“If you pose the question of ‘What defines us as human beings?’ to people around you, most likely, among the first answers that you get, they will mention ‘language’ or ‘languages’.
The ability to produce and understand language in order to satisfy our communication needs is our most prized human ability. It is a fundamentally human capacity that relies on unique brain circuitry. It has probably played a decisive role in our evolving as a species…”
Our examples here will be from English, but think about the principles that apply to other languages, the languages you know. Everybody has heard a finite number of sentences in their life, but is capable of producing an infinite amount of sentences. For example, «The sun is shining» is an acceptable sentence in English, while «The sun shining is» does not seem like a good sentence, although we probably understand what it means. The ability of the speaker is not only to produce an infinite number of sentences, but also to distinguish them from the ones that are not acceptable.
This is true not only of sentences, but of larger and smaller units of language, such as phrases or conversations. Since the seminal work of the American linguist Noam Chomsky in the ‘50s transformed linguistics as a science, linguists have come to study human language as another attribute of our species. This research tradition proposes that the ability to speak language– is just one natural product, just like our ability to see and to walk– and it is because we are human beings that we have this ability to speak. What is language acquisition? What do we know when we know language? Learners have to be surrounded by linguistic input.
And that can be provided by parents, siblings, peers, in general the linguistic community of the learner, no matter whether the learner is a child or a second language learner. For example, a second language learner of Mandarin Chinese may be exposed to the language in a classroom, but may improve when she goes on a visit or study abroad to China. The point is that there is nothing genetic about language, and it is the language acquisition ability that is genetic. But the specific languages come from the inputs that we are exposed to throughout our life times.
