what is shipping

Shipping refers to the physical process of transporting commodities, merchandise, goods, and cargo from one point to another. The term originally referred to transport by sea, but in American English, it has been extended to refer to transport by land or air as well. Ground shipping can be made by train or by truck, and it is typically more affordable than air but more expensive than sea, especially in developing countries where inland infrastructure may not be efficient. Shipping can also refer to the act or business of a person or thing that ships, or a number of ships, especially merchant ships, taken as a whole. In addition, the term "shipping" has taken on new life thanks to people, predominantly teens, using it to describe their support for a romantic relationship between two individuals.
