So-called "path predicates" in White Hmong (Hmong-Mien) have been described as having both verbal and prepositional uses. This paper examines the syntactic properties of Hmong path predicates across four syntactic environments. On the basis of two co-occurrence restrictions (which, following Johnston 2024, are taken as categorial diagnostics), this paper argues that (i) Hmong path predicates are underlyingly prepositional across all environments in which they occur, and (ii) in one particular syntactic environment, Hmong path predicates give rise to deprepositional verbs.
