This paper aims to investigate the nature of covert and overt subjects in Uyghur attitude reports. Following up on the authors' previous work, they argue that covert subjects in Uyghur are distinct from their overt nominative-marked counterparts, despite receiving obligatory shifted reading and triggering matching agreement. By drawing inspiration from studies on null subject licensing in other Partial Null Subject (PNS) languages, they propose that the covert subject in Uyghur is an anaphor, controlled by an antecedent in a higher clause, while the overt subject functions as an indexical. Furthermore, despite sharing certain characteristics with PRO-control, their analysis show that the control of 1st-person null subjects in Uyghur finite clauses exhibits a greater degree of freedom than PRO-control. This observed pattern aligns with the control of 3rd-person null subjects in other typical PNS languages.
