The term "Common Language" refers to a shared means of communication between two or more individuals, groups or organizations. It is usually spoken and understood by all parties involved in order for them to convey their thoughts, ideas, feelings, needs and desires effectively without any confusion or misunderstanding. A common language can be a native tongue, a second language learned through education or exposure, or even a specialized jargon used within a particular profession or industry. It is an essential tool in facilitating communication, building relationships, conducting business, and promoting understanding among people from diverse backgrounds.
