Both a construction with expletive subject and 'rain' as a verb, and a construction with 'rain (n.)' as a subject and 'fall' as a verb are attested in Kriol. The latter corresponds to the construction in at least some of the traditional languages of the area. According to Hudson (1985: 59), a construction with expletive subject is used more generally in 'ambient' expressions in Kriol.
