281. A noun used to describe another, and denoting the same person or thing, agrees with it in case. The descriptive noun may be either an appositive (§ 282 below) or a predicate noun (§ 283  below).

 

Apposition

282. A noun used to describe another, and standing in the same part of the sentence with the noun described, is called an Appositive, and is said to be in apposition.

[Here both nouns are in the predicate.]

[Here senex, though in apposition with the subject of didicī, really states something further: viz., the time, condition, etc., of the act (Predicate Apposition).]

a. Words expressing parts may be in apposition with a word including the parts, or vice versa (Partitive Apposition.

Predicate Noun or Adjective

283. With sum and a few other intransitive or passive verbs, a noun or an adjective describing or defining the subject may stand in the predicate. This is called a Predicate Noun or Adjective. The verb sum is especially common in this construction, and when so used is called the copula (i.e. connective). Other verbs which take a predicate noun or adjective are the so-called copulative verbs signifying to become, to be made, to be named, to appear, and the like.

284. A Predicate Noun or Adjective after the copula sum or a copulative verb is in the same case as the Subject.

I have always been an adviser of peace.

Quae pertinācia quibusdam, eadem aliīs cōnstantia vidērī potest. (Marc. 31)

Dīcit nōn omnīs bonōs esse beātōs.

a. A predicate noun referring to two or more singular nouns is in the plural.

Cōnsulēs creantur Caesar et Servīlius. (B. C. 3.1)
Cæsar and Servilius are elected consuls.

b. Sum in the sense of exist makes a complete predicate without a predicate noun or adjective. It is then called the substantive verb.

Sunt virī fortēs.
There are (exists) brave men.

Cf. Vīxēre fortēs ante Agamemnona (Hor. Od. 4.9.25)
Brave men lived before Agamemnon.
