The language can be divided into three phases. The pre- lingual phase of 0 to 1 year , the early – lingual phase of from 1 to 2.5 years and the stage of differentiation of 2.5 to 5 years. The language can be divided into expressive (express) and passive (understanding) language. Throughout this period, the expressive language develops from crying to a full speech/language development and passive language to a full understanding of what is said.
In the first period the child can only cry to express. His displeasure The crying is differentiated. Parents/guardians recognize the different “cries” of their child. In the third month, the child begins to babble and get the fun sounds. The babbling begins with chatter and crows and proceeds via vowel -like sounds to really babble (same sounds in succession). In the eighth month, the child begins to imitate sounds and intonation, a certain observable. The child gets more and more fun and games sound begins to babble. In the tenth month, a child also able to find a familiar object when prompted (passive language). At the end of the first year a child can say the words “mama” and “dada”, but it is not always justified. An outright ban and a simple admonition to be understood by the child. An one year old child understands words like “mama” and “day” and has a vocabulary of between 3 and 50 words. The vocabulary makes a tremendous growth and as a child 3 years old has a vocabulary of over 100 words and uses two word utterances. By the time a child is four years, the vocabulary covers more than 1000 words, appoints the things it sees and it is understandable to strangers. At age five, the speech/language development (also grammatically) is basically fully developed.
