When analyzing the two modes of language, these are the main points of study in which meaning, sound and grouping is allocated. These are also prime when looking at the evolution of language as a whole, or when looking at the etymology of certain words or phrases. This can also be useful when studying how spoken and written language have become different over time and separated, in order to identify themselves as two very different modes of language. This is due to social changes and the evolution of spoken language as a result of the popular culture surrounding certain personalities of people. Whilst spoken language has evolved thus, written language has remained formal, but has evolved within its own range; making changes to spellings and sounds during the 'Great Vowel Shift' (Jespersen, 1987), as vowel sounds became more standard. This proves, that for written language, Standard English has remained a popular choice as opposed to growing ever closer to the spoken discourse. Standard English in written language has also has certain rules that need to be adhered to as they have not given into the popular ideologies of social change; making the language of writing standardize as more formal and similar across most countries in which English is the first language. .
Spoken language is a combination of 'the various muscles and organs that act together to produce speech sounds.' (McGregor, 2014). Whereas, written language is the orthography involved when producing the letters as a visual symbol. .
Spoken Language is similar to written language as there are certain sounds obeyed such as the '-sh' and '-ch' sounds. Also, there are a number of rules that need to be adhered to in order to be understood by the conversation participant. These sounds and rules are practiced nationally in the language such as the sounds for letters and groups of letters, 'syntactic structures and rhythm'.
