The aim of the present pater is to propose a new typology of relative clause constructions along the line of to what extent particular languages use the syntax-based (SB) strategy and the pragmatics-based (PB) strategy. It is pointed out that the notion of ‘relevance’ plays an important role in relating the head and the relativeclause. In §.5.2, what factors are relevant to the PB stratgy is suggested. In §.6.1, it is implied that the new typology put forward here is based on the gradation of syntax-dominant (SD) languages and pragmatics-dominant (PD) ones. Appendix includes the data to be collected and some of the PB examples from Japanese, Korean and Ainu.
