Towards a framework of contact etymology

This paper is structured as follows. Section two discusses the question when the investigation of a contact etymology is warranted by the data and research history. Section 3 introduces the so-called Blueprint Principle, which is used to reconstruct possible contact languages in situation in which the contact language is unknown. In section 4 the core elements of a contact explanation are discussed, and section 5 outlines a methodological framework for the position of contact etymologies. The main points of this paper are summarized in section 6.
