Traversing the “where” landscape: Vietnamese đâu and the clausal architecture of Vietnamese
摘要
As far as Vietnamese information-seeking questions are concerned, đâu is a wh-item equivalent to the English where. However, in a variety of non-canonical construals, đâu can be devoid of its original interrogative meaning. Specifically, we contend that pre-verbal đâu is a negator taking the widest scope, acting to reject the truth of a proposition/inference. Sentence-initial đâu, on the other hand, serves to deny or object to a discourse-salient utterance. Additionally, there are two distinct sentence-final đâu’s, each occupying a position in a separate domain beyond the traditional CP. One heads a Commitment Phrase, conveying the speaker’s public endorsement of a contradiction to a previous statement, while the other occupies an even higher position at a Speech Act Phrase, marking the speaker’s call for a specific show-me response from the addressee. We draw upon cross-linguistic evidence to further substantiate our claims on empirical grounds, which in turn sheds new light on the fine structure of the Vietnamese left periphery.
