Abstract
A grey proposition is first introduced. Based on it, the new definition of a grey set is given from the view point of set theory. The greyness of a grey set indicates the uncertainty of the connotation for a concept. Some properties of grey sets are pointed out. By using the difference information entropy, the grey degree, which quantifies the greyness of a grey set, is got.
