'ADJECTIVES OF THE THIRD DECLENSION • Ī-STEMS
250. Adjectives are either of the first and second declensions (like bonus, aeger, or līber), or they are of the third declension.

EXERCISES
First learn the special vocabulary, p. 293.
I.The Romans invade the Enemy’s Country. Ōlim peditēs Rōmānī cum equitibus vēlōcibus in hostium urbem iter faciēbant. Ubi nōn longē āfuērunt, rapuērunt agricolam, quī eīs viam brevem et facilem dēmōnstrāvit. Iam Rōmānī moenia alta, turrīs validās aliaque opera urbis vidēre poterant. In moenibus stābant multī prīncipēs. Prīncipēs ubi vīdērunt Rōmānōs, iussērunt cīvīs lapidēs aliaque tēla dē mūrīs iacere. Tum mīlitēs fortēs continērī ā proeliō nōn poterant et ācer imperātor signum tubā darī iussit. Summā vī omnēs mātūrāvērunt. Imperātor Sextō lēgātō impedīmenta omnia mandāvit. Sextus impedīmenta in summō colle conlocāvit. Grave et ācre erat proelium, sed hostēs nōn parēs Rōmānīs erant. Aliī interfectī, aliī captī sunt. Apud captīvōs erant māter sororque rēgis. Paucī Rōmānōrum ab hostibus vulnerātī sunt. Secundum proelium Rōmānīs erat grātum. Fortūna fortibus semper favet.
