What is an objective noun and a possessive noun?

Nouns serving as objects always come post-verb in the syntax. For example, in ‘he stroked the dog’, ‘the dog’ is the object and ‘dog’ would be the noun. Possessive nouns indicate some form of possession. For example, in ‘the dog’s lead’, ‘dog’s’ is indicating that the ‘lead’ is a possession of the dog. Hope that helps 😊.
