Comment on the use of the group-genitive and double genitive in Modern English.

The group-genitive and double genitive in Modern English are both ways of expressing possession or association between two or more nouns.

The group-genitive is used when a single noun is followed by a plural noun to indicate that the possession or association is shared by the group as a whole. For example, "the company's employees" indicates that the possession or association belongs to all employees of the company as a group.

The double genitive, on the other hand, is used when a noun is followed by both a singular and a plural noun to indicate that the possession or association is shared by both the individual and the group as a whole. For example, "John's and his friends' car" indicates that the possession or association belongs to both John individually and his friends as a group.

Overall, the group-genitive and double genitive are both useful ways of expressing possession or association in Modern English, allowing for more nuanced and specific descriptions of relationships between nouns.
