“…Despite its importance, not many comprehensive studies are as yet available for Chinese. Synchronically, there are studies on modal adverbs and modal auxiliaries in Modern Chinese, such as Alleton (1977;, Li (2004), Lin (2012) and Sparvoli (2015), while for Literary Chinese, the modal auxiliary verbs of possibility and of volition have been discussed by Peyraube (1999;2001), Liu (2000) and Meisterernst (2008a;2008b). Diachronically, some studies (e.g., Li 2004) proffer a brief history of canonical Mandarin modal verbs (neng 'can' , hui 'can' , yao 'should, must' , ying 'should' , de 'have to'); others focus on the diachronic development of specific modal verbs, such as modal verbs of obligation-dang 'should' and ying 'should' (Meisterernst 2011;2020), bixu 'must/have to' (Zhu 2005) and yao 'should, must' (Ma 2002), and modal verbs of volition-gan 'dare to' ken 'willing, can' and yuan 'willing' (Peyraube & Li 2012).…”
