109 results about "Partitive" patented technology

In linguistics, the partitive is a word, phrase, or case that indicates partialness. Nominal partitives are syntactic constructions, such as "some of the children", and may be classified semantically as either set partitives or entity partitives based on the quantifier and the type of embedded noun used. Partitives should not be confused with quantitatives (also known as pseudopartitives), which often look similar in form, but behave differently syntactically and have a distinct meaning.
