1.0 Introduction. The intention of this report is to highlight the differences between speaking and writing English in various contexts. Although both are valuable forms of communication, the differences between them date back to the origin of humanity. Speech is an inherent 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, para. 2). ). The difference between these uses of language is not just genetic, but also in how they are used comparatively in everyday life in similar contexts. This can change depending on the social status, culture and relationships between those communicating. The way the use of speech and writing changes depending on the need to be formal or informal is called "register." The contexts that will be explored in this text will be located within the classroom and within the family home. The purpose of this report is to emphasize that the meaning of words can be changed depending on the situation in which they are used and by whom and how.2.0 Classroom Context. An essential part of children's learning in a classroom context, particularly in the early years, is knowing how to adapt their language to be in the correct register for use in an educational context. This skill must be explicitly taught by educators, so that every child is able to understand what is expected of them and no child is disadvantaged due to poor use of Standard Australian English.2.1 Speech .2.1.1- Student to student-students to communicate with each other in a classroom environment, one generally uses very informal speech, consistent with the vernacular...... middle of paper .... .. is likely to be highly colloquial and written in a restricted code version. In general, the style is very informal and does not use correct grammar, punctuation, or sentence structure. This is where our writing becomes more like “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 today I'm blowing bubbles for everyone." This type of note is written in a restricted code with no formal structure, but will generally be understood by the receiving parent. Adult-adult - use the example of a dinner in the oven to explain how writing can be taken out of context to appear angry or terse. and say how an x ​​as a symbol could completely change the tone of the writing.
