Acquiring the polysemous adverb HAI in Chinese by English-speaking, Japanesespeaking, and Korean-speaking CSL learners.

Using corpus analysis and error analysis，this study investigates Englishspeaking, Japanese-speaking，and Ko re an-speaking Chinese learners' acquisition of various meanings of hat in Mandarin Chinese，including its temporal meaning still, yet' as well as its abundant atemporal meanings involving addition, comparison and counter-expectation. We found a preponderance of misselection errors across the three groups of learners. The next most common error type for the Japanese-speaking and Koreanspeaking learners was omission，while omission and over-inclusion were equally challenging for the English-speaking learners. Further analysis of errors in misselection shows that many learners failed to distinguish the temporal hat from the atemporal haishi required in a concessive sentence for the counter-expectation meaning.
