→"expensive" is the adjective;
→"car" is the noun modified by the adjective phrase.
→ "a very expensive car" is a noun phrase.
Appearing outside the noun phrase that they modify and typically following a linking verb.
The exercise was unbelievably difficult.
→"unbelievably difficult" is the adjective phrase;
→"difficult" is the adjective;
→"The exercise" is the noun phrase modified by the adjective phrase.

1. Come at the beginning:

→"keen" initiate the adjective phrase "keen on her."
2. Be in a medial position:
