Sometimes I see words like I mentioned that use without using article the.
Is there any difference in meaning?
Because as far as I know we should use article the for the possessive form of non-living things and animals.
For example: Communism is based on common ownership of the means of production,and communists believe in a classless society.
My question is that sometimes I see some words like "means of transport/communication/expression", why we don't use "the means of transport" instead?
