Thought is the root cause of language. Without thought expression is not born. The method of expression is the nucleus of a language. These methods differ and hence there are many languages in the world.

Articulation is the backbone of any language. In other words being articulate is language. First of everything, a thought occurs in the human brain. The very thought has to be expressed. The very expression is done through articulate sounds.

Just imagine what would happen if the expression is done through inarticulate sounds! Nothing can be comprehended by the listener! Thus articulation becomes the very life of any language for that matter.

Articulation paved the way for the birth of hundreds of languages all over the globe. Phonology is a very significant branch of linguistics without which a language cannot be a spoken one.
