Therefore, an appositive with a noun in the nominative case would be a noun or noun phrase that renames a noun that is also in the nominative case.
Here are some examples:
* The poet, _John Keats_, was known for his romantic verse. (Here, "_John Keats_" is the appositive, and both it and "poet" are in the nominative case because they are the subjects of the verb "was known").
* My friend, _the artist_, is having an exhibition next month. (Here, "_the artist_" is the appositive, and both it and "friend" are in the nominative case because they are the subjects of the verb "is having").
* The teacher, _a kind and patient woman_, was loved by her students. (Here, "_a kind and patient woman_" is the appositive, and both it and "teacher" are in the nominative case because they are the subjects of the verb "was loved").
It is important to note that the nominative case is usually only used for subjects and predicate nominatives. If the noun being renamed is in another case (e.g., objective or possessive), the appositive will also be in that case.
For example:
* I gave the book to _my brother_, the doctor**. (Here, "_the doctor_" is the appositive, and both it and "brother" are in the objective case because they are the objects of the preposition "to").
