Abstract

This thesis proposes that the typological distinctions among languages with respect to the formation of wh-questions can be attributed to the availability of question particles and the properties of wh-words. It is argued that the availability of question particles correlates with the lack of syntactic wh-movement. A theory of Clausal Typing is proposed to account for this correlation. In particular, languages employ either question particles or syntactic wh-movement to type a clause as a wh-question. It is shown that the Principle of Economy of Derivation predicts that no language has the option of alternating between the two methods of Clausal Typing and thus there are no languages with "optional movement" of wh-words and movement of one wh-word is sufficient to type a clause as a wh-question. Apparent counterexamples to the proposal are discussed. It is argued that in languages with apparent optional fronting of wh-words , sentences with a clause-initial wh-word are clefts. In addition, it is shown that in languages which front multiple wh-words in multiple questions, the wh-words are morphologically complex and need to satisfy a licensing requirement independent of Clausal Typing. ;The internal structure of wh-words in an "in-situ" language, namely Mandarin Chinese is also examined. It is shown that wh-words in Mandarin are indefinite NPs, which lacks quantificational force, and they are polarity sensitive. In addition, Two LF operations are discusssed: Quantifier Raising and LF wh-movement. It is shown that the lack of scope ambiguities in Mandarin can be attributed to lexical properties of indefinite NPs. Arguments for and against LF wh-movement as well as the landing site of wh-words at LF are examined. It is shown that evidence against LF wh-movement does not hold and arguments against adjunction of wh-words to IP at LF will be provided.
