1. When the clause depends upon another containing a
wish, a command, or a question, expressed indirectly,
though not strictly in the form of Indirect Discourse: -
- animal sentit quid sit quod deceat
(Off. i. 14), an animal feels what it is that is fit.
- huic imperat quás possit
adeat cívitátés (B. G. iv. 21), he
orders him to visit what states he can.
- hunc sibi ex animó scrúpulum,
quí sé diés noctísque stimulat ac
pungit, ut évellátis postulat (Rosc. Am. 6),
he begs you to pluck from his heart this doubt that goads and stings
him day and night. [Here the relative clause is not a part of the
Purpose expressed in évellátis, but is an assertion
made by the subject of postulat.]
