Language is alive. It constantly evolves and changes, which is what keeps it alive. Applied Linguistics determines how we communicate (speak and write). We negotiate the language to communicate an idea. Pulling ideas together helps us to come up with a definition. The integration of the four skills is important; we take the knowledge we have acquired and use it for a purpose.

Pronunciation is more important that accent. If you pronounce clearly, everyone will understand the message. We can interpret what our students say because we listen to their voices. 

Phonetics is the art of pronouncing and perceiving any and every speech sound used communicatively in the languages of this world (Laver, 1994).

Morphology is a field of linguistics focused on the study of the forms and formation of words in a language. Words in a language consist of one element or elements of meaning which are called "morphemes". Languages vary widely in this matter.

Semantics is reading between the lines.

It is the study of meaning that is used to understand human expression through language. The more confident you are with the language, the more straight and forceful you go.

Phonetics has a lot to do with semantics. My intonation can communicate something different.

Syntax is the study of how sentences are structured or how words are combined with others to form sentences and in what order. By reading, students learn sentence structure and see the basics of syntax.

Pragmatics is about the invisible meaning. Context affects the interpretation of the message, for example:

A:"How's your son?"

B: "He's grown another foot."
