Singulative

In linguistics, a singulative form is a form of a noun which expresses the idea of an individual example of the noun; for instance, "snowflake" may be considered a singulative from "snow". In some languages, singulatives can be productively formed from collective nouns; e.g. Standard Arabic حجر ḥajar "stone" > حجرة ḥajarā "(individual) stone", بقر baqar "cattle" > بقرة baqarā "(single) cow"
