An Attributive Adjective simply qualifies its noun without the intervention of a verb or participle, expressed or implied: as, —bonus imperātor, a good commander;stellae lūcidae, bright stars;verbum Graecum, a Greek word.
All other adjectives are called Predicate Adjectives:—
stellae lūcidaeerant, the stars were bright.
sit Scīpiō clārus (Cat. 4.21), let Scipio be illustrious.
hominēsmītīs reddidit (Inv. 1.2), has rendered men mild.
tria praedia Capitōnīpropria trāduntur (Rosc. Am. 21), three farms are handed over to Capito as his own.
cōnsilium cēpēruntplēnum sceleris (id. 28), they formed a plan full of villany.
Adjectives, Adjective Pronouns, and Participles agree with their nouns in Gender, Number, and Case:—
vir fortis, a brave man.
illa mulier, that woman.
urbium māgnārum, of great cities.
cum ducentīs mīlitibus, with two hundred soldiers.
imperātor victus est, the general was beaten.
secūtae sunt tempestātēs, storms followed.
With two or more nouns the adjective is regularly plural, but often agrees with the nearest (especially when attributive):—
Nīsus et Euryalus prīmī (Aen. 5.294), Nisus and Euryalus first.
Caesaris omnī et grātiā et opibus fruor (Fam. 1.9.21), I enjoy all Cæsar's favor and resources.
A collective noun may take an adjective of a different gender and number agreeing with the gender and number of the individuals implied (synesis, § 280. a):—
pars certāre parātī (Aen. 5.108), a part ready to contend.
colōniae aliquot dēductae, Prīscī Latīnī appellātī (Liv. 1.3), several colonies were planted (led out) [of men] called Old Latins.
multitūdō convictī sunt (Tac. Ann. 15.44), a multitude were convicted.
māgna pars raptae (id. 1.9), a large part [of the women] were seized.
One adjective may belong in sense to two or more nouns of different genders. In such cases,—
An Attributive Adjective agrees with the nearest noun:—
multae operae ac labōris, of much trouble and toil.
vīta mōrēsque meī, my life and character.
sī rēs, sī vir, sī tempusūllum dīgnum fuit (Mil. 19), if any thing, if any man, if any time was fit.
A Predicate Adjective may agree with the nearest noun, if the Nouns form one connected idea:—
factus est strepitus et admurmurātiō; (Verr. 1.45), a noise of assent was made (noise and murmur).
But generally, a Predicate Adjective will be masculine, if nouns of different genders mean living beings; neuter, if things without life:—
uxor deinde ac līberī amplexī (Liv. 2.40), then his wife and children embraced him.
labor (M.) voluptāsque (F.) societāte quādam inter sē nātūrālī sunt iūncta (N.) (id. 5.4), labor and delight are bound together by a certain natural alliance.
If nouns of different genders include both living beings and things without life, a Predicate Adjective is sometimes masculine (or feminine), sometimes neuter, and sometimes agrees in gender with the nearest if that is plural:—
rēx rēgiaque classis ūnā profectī (Liv. 21.50), the king and the royal fleet set out together.
nātūrāinimīca sunt lībera cīvitās et rēx (id. 44.24), by nature a free state and a king are hostile.
lēgātōs sortēsque ōrāculī exspectandās (id. 5.15), that the ambassadors and the replies of the oracle should be waited for.
Two or more abstract nouns of the same gender may have a Predicate Adjective in the neuter plural (cf. § 289. c):—
stultitia et temeritās et iniūstitia ... sunt fugienda (Fin. 3.39), foliy, rashness, and injustice are [things] to be shunned.
Adjectives are often used as Nouns (substantively), the masculine usually to denote men or people in general of that kind, the feminine women, and the neuter things:—
omnēs, all men (everybody).
omnia, all things (everything).
mâiōrēs, ancestors.
minōrēs, descendants.
Rōmānī, Romans.
barbarī, barbarians.
līberta, a freedwoman.
Sabīnae, the Sabine wives.
sapiēns, a sage (philosopher).
amīcus, a friend.
bonī, the good (good people).
bona, goods, property.
Certain adjectives have become practically nouns, and are often modified by other adjectives or by the possessive genitive:—
tuus vīcīnus proximus, your next-door neighbor.
propinquī cēterī, his other relatives.
meus aequālis, a man of my own age.
êius familiāris Catilīna (Har. Resp. 5), his intimate friend Catiline.
Leptae nostrī familiārissimus (Fam. 9.13.2), a very close friend of our friend Lepta.
When ambiguity would arise from the substantive use of an adjective, a noun must be added:—
bonī, the good;omnia, everything (all things); but,—
potentia omnium rērum, power over everything.
Many adjectives are used substantively either in the singular or the plural, with the added meaning of some noun which is understood from constant association:—
āfricus [ventus], the southwest wind;Iānuārius [mēnsis], January;vitulīna [carō], veal (calf's flesh); fera [bēstia], a wild beast;patria [terra], the fatherland;Gallia [terra], Gaul (the land of the Gallī); hīberna [castra], winter quarters;trirēmis [nāvis], a three-banked galley, trireme;argentārius [faber], a silversmith;rēgia [domus], the palace;Latīnae [fēriae], the Latin festival.
Neuter Adjectives are used substantively in the following special senses:—
The neuter singular may denote either a single object or an abstract quality:—
raptō vīvere, to live by plunder.
in āridō, on dry ground.
honestum, an honorable act, or virtue (as a quality).
opus est mātūrātō, there is need of haste. [Cf. impersonal passives § 208. d.]
The neuter plural is used to signify objects in general having the quality denoted, and hence may stand for the abstract idea:—
honesta, honorable deeds (in general).
praeterita, the past (lit., bygones).
omnēs fortia laudant, all men praise bravery (brave things).
A neuter adjective may be used as an appositive or predicate noun with a noun of different gender (cf. § 287. a):—
trīste lupus stabulīs (Ecl. 3.80), the wolf [is] a grievous thing for the fold.
varium et mūtābile semper fēmina (Aen. 4.569), woman is ever a changing and fickle thing.
malum mihi vidētur esse mors (Tusc. 1.9), death seems to me to be an evil.
A neuter adjective may be used as an attributive or a predicate adjective with an infinitive or a substantive clause:—
istuc ipsum nōn esse (Tusc. 1.12), that very “not to be.”
hūmānum est errāre, to err is human.
aliud est errāre Caesarem nōlle, aliud nōlle miserērī; (Lig. 16), it is one thing to be unwilling that Cæsar should err, another to be unwilling that he should pity.
Besides their regular signification (as in English), the forms of comparison are used as follows:—
The Comparative denotes a considerable or excessive degree of a quality: as,—brevior, rather short;audācior, too bold.
The Superlative (of eminence) often denotes a very high degree of a quality without implying a distinct comparison: as,—mōns altissimus, a very high mountain.
With quam, vel, or ūnus the Superlative denotes the highest possible degree:—
quam plūrimī, as many as possible.
quam maximē potest (maximē quam potest), as much as can be.
vel minimus, the very least.
vir ūnus doctissimus, the one most learned man.
For the Superlative with quisque, see § 313. b. For the construction of a substantive after a Comparative, see §§ 406, 407; for that of a clause, see § 535. c, 571. a. For the Ablative of Degree of Difference with a Comparative (multō etc.), see § 414.
Superlatives (and more rarely Comparatives) denoting order and succession—also medius, [cēterus], reliquus—usually designate not what object, but what part of it, is meant:—
summus mōns, the top of the hill.
in ultimā plateā, at the end of the place.
priorāctiō, the earlier part of an action.
reliquī captīvī, the rest of the prisoners.
in colle mediō (B. G. 1.24), half way up the hill (on the middle of the hill).
inter cēteram plānitiem (Iug. 92), in a region elsewhere level.
