The wh-questions formation has been studied typologically across various languages. Within the Principle and Parameter (P&P) by Chomsky (1981), it has long been suggested that wh-phrases licences the relation to some clause-peripheral Xo positions referred to as a C[+Q]. In many languages, this type of obligatory dependency is analysed as movement between the position in which a wh-phrase is understood to be base-generated and the Spec of the C. In some languages, like Chinese and Japanese, wh-phrases do not have to be moved in overt syntax. Also, other languages do not move the wh-phrases into Spec of the C, but the position to the left of V. Jayaseelan (2004) argues that in some languages, wh-phrases are moved into the Spec of a Focus Phrase immediately above vP, which is the TP-Internal Focus position. Accordingly, I propose a TP-Internal Focus Probe in Korean wh-questions. Since Korean wh-phrases sometimes undergo wh-movement and whereas they sometimes stay in-situ, focus probe ([-Focus]) enters into Agree only with wh-phrases containing [+Focus] features, which is its goal. Then, it fulfills Probe-Goal Union (PGU) and as a result, it demonstrates that only wh-phrases with [+Focus] features undergo wh-movement in Korean.
