Social abilities are real entities, which are usually called resources in sociological literature. In the author's interpretation, the entities expressed in the concepts of social power and social capital are made up of social abilities. However, in the present paper he only deals with the concept of social ability and the types of social abilities; but he does not make an attempt at determining the concepts of social power and social capital based on the concept of social ability. The author first typifies acting abilities and determines the concept of social ability as a special type of acting ability. Then he makes a distinction between pure-institutional and personal social abilities, as well as social qualifications and exclusive information within social abilities. Analysing these types he points out the nature of social abilities. The present paper is published in two parts. In the first part the author analyses pure-institutional social abilities, and in the second part he deals with personal social abilities, social qualifications and exclusive information.
