Answer and Explanation:
Language creates communication and communication is able to create bridges between societies in all parts of the world, allowing connections to be made between all peoples. This creates a global unity, connects different cultures and allows for the joint thinking of all the inhabitants of the planet who can act together to solve global problems, to share their privileges and encourage positive elements across the planet. In short, language and communication provide connections and that builds a global and unified society.
The term that would best fit as the opposition of an argument would be a "counterclaim." By definition, a counterclaim is a term used to describe a claim wherein it serves as a "rebut" from the person that is the subject of the accusation. It is of course defined in the constitution, that the accused has the right to defend himself/herself thus making a counterclaim.
Something that is ordinary or common can also be called plain, a homophone for that word would be plane. Similarly, something that is to see how heavy something is, would be to weigh, a homophone for that word being way.
