cūrīs līberātus, freed from cares;
Caesar hostēs armīs exuit, Caesar stripped the enemy of their arms;
caret sēnsū commūnī, he lacks common sense;
auxiliō eget, he needs help;
bonōrum vīta vacua est metū, the life of the good is free from fear.
NOTE 1.—Yet Adjectives and līberō may take the preposition ab,—regularly so with the Ablative of persons; as,—
urbem ā tyrannō līberārunt, they freed the city from the tyrant.
NOTE 2.—Indigeō usually takes the Genitive. See [§ 212], 1, a.
2. Of Verbs signifying to keep from, to remove, to withdraw, some take the preposition, others omit it. The same Verb often admits both constructions. Examples:—
abstinēre cibō, to abstain from food;
hostēs fīnibus prohibuērunt, they kept the enemy from their borders;
praedōnēs ab īnsulā prohibuit, he kept the pirates from the island.
3. Other Verbs of separation usually take the Ablative with a Prepositon, particularly compounds of dis- and sē-; as,—
dissentiō ā tē, I dissent from you;
sēcernantur ā nōbīs, let them be separated from us.
4. The Preposition is freely omitted in poetry.
