1. Interestingly, these zero imperatives have no other uses; that is, they are not used for other default functions, such as perfective or present habitual. This fact suggests that zero imperatives arise directly as imperatives and not via some other functions (see Bybee [1990] 1994 for discussion). Non-zero expression of imperative must arise as overt material grammaticizes (Bybee, Perkins, & Pagliuca 1994: 210).2. Implicational core: If zero-marked imperatives have meanings other than 2SG, then they will also have 2SG meaning.
