[*] 500. The Gerundive when used as a Participle or an Adjective is always passive, denoting necessity, obligation, or propriety. In this use of the Gerundive the following points are to be observed:—
- The gerundive is sometimes used, like the present and perfect participles, in simple agreement with a noun:—
- The most frequent use of the gerundive is with the forms of esse in the Second (or passive） Periphrastic Conjugation (see § 196):—
- The neuter gerundive of both transitive and intransitive
verbs may be used impersonally in the second periphrastic
With verbs that take the dative or ablative, an object may be
expressed in the appropriate case; with transitive verbs, an
object in the accusative is sometimes found:—
- “temporī serviendum est ” (Fam. 9.7.2) , one must obey the time.
- lēgibus pārendum est, the laws must be obeyed.
- “ ūtendum exercitātiōnibus modicīs” (Cat. M. 36) , we must use moderate exercis<*>
- “ agitandumst vigiliās” (Pl. Trin. 869) , I have got to stand guard.
- “ via quam nōbīs ingrediendum sit ” (Cat. M. 6) , the way we have to enter.
- After verbs signifying to give,
deliver, agree for, have,
demand,1 a gerundive in agreement with the object
is used to express purpose:—
- “redēmptor quī columnam illam condūxerat faciendam” (Div. 2.47) , the contractor who had undertaken to make that column. [The regular construction with this class of verbs.]
- “aedem Castoris habuit tuendam” (Verr. 2.1.150) , he had the temple of Castor to take care of.
- nāvīs atque oneraadservanda cūrābat (id. 5.146), he took care that the ships and cargoes should be kept.
