On the licensing and recovering of imperative subjects

Imperative verbs displaying no overt inflectional marking for their mood specification never demand any explicit identification of their addressee. Consequently, the formally unmarked imperative is generally considered to be 'subjectless'. Nonetheless, in this paper, I argue that formally unmarked imperatives always license a syntactic subject. While in some languages this subject may be optionally phonetically realized, it is usually represented as a specific imperative zero pronoun that shares mixed properties of the more common empty pronouns pro and PRO.
