This research deals with the similarities and differences found in the left periphery of Korean and Spanish and introduces various parameters that can be applied to variations within that clausal domain CP. In particular, this work provides analyses that unlike Spanish data that the syntactic overt movement of constituents to the left periphery gives rise to discourse effects, as argued by Rizzi’s (1997) cartographic project, the covert movement of constituents or operators in Korean yields topicalization and focalization. Furthermore, focusing on ‘constrastive readings’ found in both languages, this paper points out that FinP with [+C] feature evokes various phenomena related to discourse effects; (i) scrambling, topic subject, Contrastive Topic/Focus in Korean and (ii) topic subject, F(ocus)F(ronting), and CLLD in Spanish, following López (2009). Finally, based on the fact that ambiguous A and A-bar natures appear in scrambling and topic subject in Korean marked by -neun and preverbal subject in Spanish, this research puts forward that FinP has the hybrid A and A-bar properties, which results in non-standard binding effects of scrambling, ambiguous (weak) cross-over effects in topicalization of Korean, as well as contrastive readings in topic subject, FF, and CLLD in Spanish. The advantage of this analysis is that it is possible to apply various “double focus phenomena” in Korean, which are not compatible with Rizzi’s (1997) cartographic project, to the existing model without setting additional functional categories. This suggests a new alternative to the Foc-Fin structure instead of Foc-Foc structure for the double focus phenomenon in Korean.
