LESSON  XVI

THE EXPRESSION OF PURPOSE (Continued)

85.  Purpose expressed by a verb in Latin {continued).
III.   Expressions with non-finite verb forms.

a.   Purpose may be expressed in Latin by the accusative of
the gerund or gerundive governed by ad.

To carry out these plans, Orgetorix is chosen, ad eas res conficiendas
Orgetorix deligitur.

I. When the principal verb is euro or do, the gerundive
is used agreeing with the object of the verb, without a
preposition.

He has a bridge built, pontem faciendum curat; he gave one legion
to Fabius to lead {to be led) among the Morini, unam legionem in
Morinos ducendam Fabio dedit.

b.   The genitive of the gerund or gerundive governed by
causa may be employed.

He is sent to have an interview, mittitur coUoquendi causa.

I. The gerundive with causa in a purpose construction in¬
volving a personal pronoun admits no distinction of gender or
number.

We have come to excuse ourselves, nostri purgandi causa venimus.
