Language is an essential aspect of human life. It is used to interact and as a means of communication. The use of it commonly related to the society, where the speakers use. They have to speak differently in different situation, condition and place. They should fit and choose the correct language. This is become socio-linguistic phenomenon.
Communication involves at least two parts. They are speaker (writer) and listener (reader), but there is another element of communication, channel, e.g. telephone, letter and TV. In communication a particular person (a group of people) sometimes does not only use a standard language which is easy to be understood by a particular group. To make the communication fluent, people also need to know the register of particular field which they frequently use in their communication.
According to Holmes, register means the language of groups of people with common interests or job or the language used in situation associated with such groups.[1] In other opinion, registers is usually characterized by vocabulary differences, either by the use of particular words or by the use of language in particular sense.[2]
The discussion of the midwife illustrates the kind of linguistic features, which may distinguish different register. When the midwife take care of the mother in giving birth she helped by nurses. There are some demands to save mothers’ life, to work fast and accurately, to be patient and need more sacrifices. In conducting her job, midwife sometimes use special language to convey message more easily. The register is often found in spoken and written words. Sometimes, the register is different from the ordinary language. For example the word “positive”, commonly it means “in a good condition” like in sentence “I get a positive response”, but in midwifery, it means “pregnancy”. The example above is only one of the large varieties of register in midwifery. By that little explanation, it is known that there are some unique words used by midwife in their conduct.
