Adjective After Verb
An adjective can come after some verbs, such as: be, become, feel, get, look, seem, smell, sound
Even when an adjective comes after the verb and not before a noun, it always refers to and qualifies the subject of the sentence, not the verb.
Look at the examples below: subject verb adjective
These verbs are "stative" verbs, which express a state or change of state, not "dynamic" verbs which express an action. Note that some verbs can be stative in one sense (she looks beautiful | it got hot), and dynamic in another (she looked at him | he got the money). The above examples do not include all stative verbs.
Note also that in the above structure (subject verb adjective), the adjective can qualify a pronoun since the subject may be a pronoun.
