§290. Adjectives with Adverbial Force

An adjective, agreeing with the subject or object, is often used to qualify the action of the verb, and so has the force of an adverb:—

• prīmus vēnit, he was the first to come (came first).
• nūllus dubitō, I no way doubt.
• laetī audiēre, they were glad to hear.
• erat Rōmae frequēns (Rosc. Am. 16), he was often at Rome.
• sērus in caelum redeās (Hor. Od. 1.2.45), mayst thou return late to heaven.
