Language use is divided into production and understanding in which each component has its own sub-parts, although they s hare core language p art (its f orm) in common. Given memory-based approach, it is claimed, at least five layers of our mind must simultaneously be activated to pass in a retrospective cycle in language use. A surface form, or a flow of sounds or letters, leads to a trigger to find an intention-in-action in any verbal communication that fits the situation of communication. This dramatically opens up a new phase to focus, once we deal with the overall aspect of language use.
