There are two kinds of Subject Complements (SC):
1) Predicate nominals or Predicate nouns
2) Predicate adjectives
SC follow linking verbs. It'd be a good idea if you went on-line and looked for a list of linking verbs. There are many on-line. By the way, linking verbs refer to states of being:
Pat seems tired / Pat = tired
As for Object Complements (OC), they modify the verb's object, like this,
They named him
Sam. (OC)
"him" functions as the object of "named", and "Sam" functions as the object of the object (i.e., and Object Complement/OC). The OC modifies, or rather tells us more about the object, 'him'. That is, "Sam is his name."
They named him
Sam (OC)
Sam is
his name (SC: Predicate noun. Note that, "is" functions as a linking verb: Sam = his name).
Here's how to tell the difference between SCs and OCs. First of all, SCs only occur after linking verbs:
Sam seems nice => Sam = nice.
The verb "seems" links "Sam" with "nice". The Subject "Sam" does not act upon "nice". One equals the other. Thus, the reason for the term "Subject Complement":
Subject + Linking Verb +
Subject Complement
EX:
Sam is
his name. /
Sam =
his name.
The Subject Complement (SC) tells us more about the Subject, whereas an Object Complement (OC) tells us more about the Object:
Subject + Verb +
Object +
Object Complement.
EX: They named
him Sam.
With OCs, it's usually possible to rephrase the object+object complement by using a form of the verb BE, like this,
Is "
Sam" an OCs?
Test: him
Sam =>
He is
Sam. (OK) :D
"Sam" of "him Sam" is an OC. Mind you, the test we did, "He is Sam" houses "Sam" as a SC, right?, because in that context "Sam" comes after a linking verb:
him
Sam (
OC)
He is
Sam (
SC: Predicate noun)
If you can find a list of linking verbs, you'll be be able to narrow down which sentences house SCs and which do not. :wink:
A quick note on determining function:
Nouns answers the question WHO or WHAT?; Adjectives answer the question WHAT KIND OF?, and Adverbs answer the questions WHERE, WHEN, HOW, and WHY?
EX: She is
a doctor. (SC: Predicate noun)
EX: He is
nice. (SC: Predicate adjective (i.e., What kind of guy?)
EX: The cat is upstairs. (Adverb: Where is the cat?)
Please note, the adverb "upstairs" doesn't rename the subject (i.e., a predicate noun), nor does it describe the subject (i.e., a predicate adjective). It adds to the meaning of the subject by telling us where, when, how, and why. Given, however, that only Subject Complements follow linking verbs, we could go so far as to suggest that adverbs in that position are technically Predicate adverbs, but one problem with that is this: Adverbs do not modify nominals, and Subject are always nominal. :wink:
All the best, :D
