1.0 Introduction. The intent of this report is to highlight the differences between speaking and writing English in a variety of contexts. While both are valuable forms of communication, the differences between them can be traced back to the origins of humanity. Speech is an intrinsic genetic ability that most humans are born with the ability to produce, while, as Bright, 2015 explains, writing is a fairly recent invention in our evolutionary history that has rules to follow (p. 1, par. 2). The difference between these uses of language is not simply genetics, but how they are used comparatively in everyday life in similar contexts. This can change depending on social status, culture and the relationship between those communicating. The way in which the use of both speech and the written word changes depending on whether it needs to be formal or informal is called 'register'. The contexts that will be explored in this text will be within the classroom and within the family home. The purpose of this report is to highlight that the meaning of words can be changed depending on the situation in which they are used, by whom and how. 2.0 School context. An essential part of learning for children within a school context, particularly in the early years, is how to adapt their language to be in the correct register for use in an educational context. This skill must be taught explicitly by educators, so that every child is able to understand what is expected of them and no child is disadvantaged due to the misuse of Standard Australian English.2.1 Speech.2.1.1- From student to student-student communicating with each other in a classroom environment generally uses very informal language in line with the vernacular... middle of the paper... is likely to be highly colloquial and written in a restricted version of code. In general, the style would be very informal and would not employ the use of correct grammar, punctuation, or sentence structure. It is in this case that our writing becomes more like a “written speech” (quote). For very young children, a note addressed to a parent may not follow any of the correct grammatical rules, but will be easily understood by the parent. For example, a four-year-old might write, "I love Daddy and I'm blowing bubbles today out of kindness." This type of note is written in a narrow code with no formal structure, but will generally be understood by the recipient parent. Adult-adult: Use the example of the baked dinner to explain how writing can be taken out of context to sound angry or terse and say how an x ​​as a symbol could completely change the tone of the writing.
