Talk:clause

xiǎng xiǎng ‘keep on thinking’ vs xiáng xiǎng ‘think for a moment’

According to Wiedenhof's A Grammar of Mandarin, page 25,

xiǎng xiǎng ‘keep on thinking’ doesn't show tone sandhi because the tones belong to separate clauses, unlike [xiáng xiǎng] ‘think for a moment’.

What meaning of "clause" is used here? --Backinstadiums (talk) 23:49, 5 October 2019 (UTC)
