[1080.] A plural subject, expressed or implied, is sometimes defined by a singular word, which is generally a collective or distributive: as,
ut ambō exercitūs suās quisque abīrent domōs, L. 2, 7, 1, so that both armies went back to their respective homes. uterque eōrum ex castrīs exercitum ēdūcunt, Caes. C. 3, 30, 3, they bring their army out of camp, each of them. heus forās exīte hūc aliquis, Pl. E. 398, hallo, you boys, come out of doors here, somebody. alius alium percontāmur, Pl. St. 370, we ask of one another. cum accidisset ut alter alterum vidērēmus, Fin. 3, 8, when it came to pass that we each saw the other. The verb sometimes agrees with the defining singular: as, quandō duo cōnsulēs, alter morbō, alter ferrō periisset, L. 41, 18, 16, since the two consuls had died, one a natural death, the other by the sword.
[1081.] A substantive in the accusative or nominative is sometimes in apposition to a thought or clause: as,
manūs intentantēs, causam discordiae, Ta. 1, 27, shaking their fists, a provocation to quarrel. pars ingentī subiēre feretrō, trīste ministerium, V. 6, 222, a part put shoulder to the mighty bier, a service sad. nec Homērum audiō, quī Ganymēdēn ab dīs raptum ait propter fōrmam; nōn iūsta causa cūr Lāomedontī tanta fieret iniūria, TD. 1, 65, nor will I lend an ear to Homer, who asserts that Ganymede was carried off by the gods for his beauty; no just reason for doing Laomedon such injustice.
[1082.] An adjective, adjective pronoun, or participle, agrees with its substantive in number, gender, and case: as,
vir bonus, H. Ep. 1, 16, 40, a good man, bona uxor, Pl. MG. 684, a good wife, oleum bonum, Cato, RR. 3, good oil. Gallia est omnis dīvīsa in partēs trēs, 1, 1, 1, Gaul, including everything under the name, is divided into three parts. et variae volucrēs nemora āvia pervolitantēs āera per tenerum liquidīs loca vōcibus opplent, Lucr. 2, 145, and motley birds, in pathless woods that flit through lither sky, fill space with carols clear.
