Partitive

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 quantitives (also known as pseudopartitives), which often look similar in form, but behave differently syntactically and have a distinct meaning. In many Romance and Germanic languages, nominal partitives usually take the form: [DP Det. + of + [DP Det. + NP]] where the first determiner is a quantifier word, using a prepositional element to link it to the larger set or whole from which that quantity is partitioned. The partitive constructions of the following languages all have the same translation, with a very similar form: Some languages, for example Estonian and Finnish, have a special partitive case. In Latin, German and Russian, the partitive is expressed by the genitive case, sometimes called the partitive genitive. Partitives can be distinguished semantically based on whether they involve a part of a whole, called entity partitives, or a subset of a larger set, called set partitives. The embedded NPs in entity partitives denote either entities at the individual level, such as "a cookie" or entities at the group level, such as "Bob and Sue". Some phrases such as ‘the linguists’ can be interpreted as either a group level entity and thus participate in an entity partitive – "half of the linguists"; alternatively, it can be interpreted as a set of entities, and thus participate in a set partitive – "one of the linguists". Set partitives contain plural countable nouns in their embedded noun phrase (NP), and can be combined with quantifier determiners such as "many", and specific numbers such as "three". Entity partitives can contain either singular countable nouns or mass nouns (and sometimes even plural countable nouns), combining with determiners such as ‘much’, or those with a fractional meaning, like ‘half’.
