【正确答案】正确答案：Radiation is a semantic process in which the primary meaning stands at the centre and the secondary meanings proceed out of it in every direction like rays. The meanings are independent of one another, but can all be traced back to the central meaning. For example, the primary meaning of the word "neck" is that part of a man or animal jointing the head to the body, but it can also mean the neck of an animal used as food. Therefore, we can say "neck" has developed through the process of radiation. Another example is the word " head". In the phrases like the head of a school, to come to a head, the word " head" has different meanings, but they all derive from special application of the central idea of head as a part of the body.
