Between two and two-and-a-half years old, the child begins producing a large number of utterances that could be classified as “multiple-word” speech. The salient feature of these utterances ceases to be the number of words, but the variation in word forms that begins to appear. Before we investigate this development, we should note a stage that is described as telegraphic speech. This is characterized by strings of words (lexical morphemes) in phrases or sentences such as this shoe all wet, cat drink milk and daddy go bye-bye. The child has clearly developed some sentencebuilding capacity by this stage and can get the word order correct. While this type of telegram-format speech is being produced, a number of grammatical inflections begin to appear in some of the word forms and simple prepositions (in, on) are also used.

By the age of two-and-a-half, the child’s vocabulary is expanding rapidly and the child is initiating more talk while increased physical activity includes running and jumping. By three, the vocabulary has grown to hundreds of words and pronunciation has become closer to the form of adult language. At this point, it is worth considering what kind of influence the adults have in the development of the child’s speech.
