366. The Dative of the Indirect Object may be used with any intransitive verb whose meaning allows.
Let arms give place to the toga.
A reply is given to Cæsar.
I have answered the heaviest charges.
Note 1— Intransitive verbs have no direct object. The indirect object, therefore, in these cases stands alone as in the second example (but cf. § 362.a).
Note 2— Cēdō (yield) sometimes takes the ablative of the thing along with the dative of the person.
a. Many phrases consisting of a noun with the copula sum or a copulative verb are equivalent to an intransitive verb and take a kind of indirect object (cf. § 367.a, Note 2).
Who testifies (is witness) to this fact?
This put an end to the raids.
b. The dative is sometimes used without a copulative verb in a sense approaching that of the genitive (cf. § 367.d, § 377).
Note — The cases in a. and b. differ from the constructions of § 367.a, Note 2 and § 377 in that the dative is more closely connected in idea with some single word to which it serves as an indirect object.
