The English language, like all languages, is interesting. Unlike some languages,there is a strong differentiation between the theoretical study and the practical application of the English Language.
An intriguing element about language is the disconnect between its theory and practice. The theory of language can be reasonably straightforward and understandable as it is studied on paper : Language in practice and in day-to-day terms of usage can be a lot more tricky. In Australian contexts, there are idiomatic factors of expression, the way words are emphasised, nuances, hidden messages, the use of colloquialisms (expressions) and so on. As well there is pitch, rhythm, tone, intonation and volume. The way in which voice is used is a very big part of language expression.
