language acquisition

Children acquire language quickly, easily, and without effort or formal teaching. It happens automatically, whether their parents try to teach them or not.

Although parents or other caretakers don't teach their children to speak, they do perform an important role by talking to their children. Children who are never spoken to will not acquire language. And the language must be used for interaction with the child; for example, a child who regularly hears language on the TV or radio but nowhere else will not learn to talk.

Children acquire language through interaction - not only with their parents and other adults, but also with other children. All normal children who grow up in normal households, surrounded by conversation, will acquire the language that is being used around them. And it is just as easy for a child to acquire two or more languages at the same time, as long as they are regularly interacting with speakers of those languages.

The special way in which many adults speak to small children also helps them to acquire language. Studies show that the 'baby talk' that adults naturally use with infants and toddlers tends to always be just a bit ahead of the level of the child's own language development, as though pulling the child along. This 'baby talk' has simpler vocabulary and sentence structure than adult language, exaggerated intonation and sounds, and lots of repetition and questions. All of these features help the child to sort out the meanings, sounds, and sentence patterns of his or her language.

When do children learn to talk?

There is no one point at which a child learns to talk. By the time the child first utters a single meaningful word, he or she has already spent many months playing around with the sounds and intonations of language and connecting words with meanings. Children acquire language in stages, and different children reach the various stages at different times. The order in which these stages are reached, however, is virtually always the same.

The first sounds a baby makes are the sounds of crying. Then, around six weeks of age, the baby will begin making vowel sounds, starting with aah, ee, and ooh. At about six months, the baby starts to produce strings of consonant-vowel pairs likeboo and da. In this stage, the child is playing around with the sounds of speech and sorting out the sounds that are important for making words in his or her language from the sounds that aren't. Many parents hear a child in this stage produce a combination like "mama" or "dada" and excitedly declare that the child has uttered his or her first word, even though the child probably didn't attach any meaning to the 'word'.
Somewhere around age one or one and a half, the child will actually begin to utter single words with meaning. These are always 'content' words like cookie, doggie, run, and see - never 'function' words like and, the, and of. Around the age of two, the child will begin putting two words together to make 'sentences' like doggie run. A little later on, the child may produce longer sentences that lack function words, such as big doggie run fast. At this point all that's left to add are the function words, some different sentence forms (like the passive), and the more complex sound combinations (like str). By the time the child enters kindergarten, he or she will have acquired the vast majority of the rules and sounds of the language. After this, it's just a matter of combining the different sentence types in new ways and adding new words to his or her vocabulary.
