hat is
coming to pass._

b) By num or -ne, without distinction of meaning; as,--

Epaminondas quaesivit num salvus esset clipeus, or salvusne esset
clipeus, _Epaminondas asked whether his shield was safe_;

disputatur num interire virtus in homine possit, _the question is
raised whether virtue can die in a man_;

ex Socrate quaesitum est nonne Archelaum beatum putaret, _the question
was asked of Socrates whether he did not think Archelaus happy_.

NOTE.--Nonne in Indirect Questions occurs only after quaero, as in the last
example above.

2. Often the Indirect Question represents a Deliberative Subjunctive of the
direct discourse; as,--

nescio quid faciam, _I do not know what to do._ (Direct: quid faciam,
_what shall I do!_)

3. After verbs of _expectation_ and _endeavor_ (exspecto, conor, experior,
tempto) we sometimes find an Indirect Question introduced by si; as,--

conantur si perrumpere possint, _they try whether they can break
through._

a. Sometimes the governing verb is omitted; as,--

pergit ad proximam speluncam si forte eo vestigia ferrent, _he
proceeded to the nearest cave (to see) if the tracks led thither._

4. Indirect Double Questions are introduced in the main by the same
particles as direct double questions (Sec. 162, 4); viz.;--

utrum ... an;
-ne ... an;
---- ... an;
---- ... ne.

Examples:--

quaero utrum verum an falsum sit, }
quaero verumne an falsum sit, } _I ask whether it_
quaero verum an falsum sit, } _is true or false?_
quaero verum falsumne sit, }

a. _'Or not'_ in the second member of the double question is ordinarily
expressed by necne, less frequently by an non; as,--

di utrum sint necne, quaeritur, _it is asked whether there are gods or
not._

5. Haud scio an, nescio an, by omission of the first member of the double
question, occur with the Subjunctive in the sense: _I am inclined to think,
probably, perhaps;_ as,--

haud scio an ita sit, _I am inclined to think this is so._

6. In early Latin and in poetry the Indicative is sometimes used in
indirect Questions.

CONDITIONAL SENTENCES.

301. Conditional Sentences are compound sentences (Sec. 164) consisting of two
parts, the Protasis (or _condition_), usually introduced by si, nisi, or
sin, and the Apodosis (or _conclusion_). There are the following types of
Conditional
