DD is diagramming this sentence:  The parents named the child Tom.  

parents = subject, named = verb, child = DO, Tom = ?

Hive, please help a girl out. 

[forty-two]

Objective complement, I think. A predicate complement renames or describes the subject; likewise, an objective complement renames or describes the object.  So, here, "Tom" renames the DO, "the child".

I would call it an appositive. I think of complements as being connected by linking verbs and appositive as directly connected as a clarifying descriptor.

Sam is my nephew. (Complement)

My nephew Sam is in 3rd grade. (Appositive)

[ChrisB]

What if the sentence is lengthened to:  The parents named the child Tom, an old family name.

'an old family name' would be an appositive.  Would Tom also be an appositive?

The longer sentence is included in a section about appositives in DD's book.

One of her classmates insists it acts as an adjective, diagrammed with a backslash after child and before Tom.

[ChrisB]

Would that adjective be considered a predicate nominative?

[8filltheheart]

A noun can have multiple appositive. I would call both appositives in your example.

I did a quick google search b/c appositives are the same person as well.  It looks like Tom would be an objective complement,
