Question

Which sentence an appositive or appositive phrase
1:that bird, the cardinal, has been singing for hours

2:the bright red bird is male.

3:the cardinal ate a sunflower seed from the bird feeder

4: in the oak tree, the bird chirped

Answer 1

3 is your answer but llet me double check

Answer 2

The correct answer is 1, because the appositive there is 'the cardinal'. An appositive is usually separated from the rest of the sentence by commas, and refers to the subject.
