Popis: In this paper we investigate two purely syntactical notions of circularity, which we call ``self-application'' and ``self-inclusion.'' A language containing self-application allows linguistic items to be applied to themselves. In a language allowing for self-inclusion there are expressions which include themselves as a proper part. We introduce axiomatic systems of syntax which include identity criteria and existence axioms for such expressions. The consistency of these axiom systems will be shown by providing a variety of different models – these models being our circular languages. Finally we will show what a possible semantics for these circular languages could look like.
