Pattern 7 of the basic simple sentences has 4 parts: Subject, predicator, direct object, and nominal object complement.
The nominal object complement is realised with nouns, nouns phrases, and pronouns. This complement gives us extra information about the direct object.
What the direct object does is to receive the action performed by the subject and the object complement then gives us more information about the direct object.
EXAMPLES:
A) Nigerians appointed Buhari the president.
Nigerians (SUBJECT)
appointed (PREDICATOR)
Buhari (DIRECT OBJECT)
the president (NOM OBJECT COMPLEMENT)
B) He painted his room white
He (SUBJECT)
painted (PREDICATOR)
his room (DIRECT OBJECT)
white (NOM OBJECT COMPLEMENT)
