follows:--

1. DECLARATIVE, which state something; as,--

puer scribit, _the boy is writing_.

2. INTERROGATIVE, Which ask a question; as,--

quid puer scribit, _what is the boy writing?_

3. EXCLAMATORY, which are in the form of an exclamation; as,--

quot libros scribit, _how many books he writes!_

4. IMPERATIVE, which express a command or an admonition; as,--

FORM OF INTERROGATIVE SENTENCES.

162. Questions may be either Word-Questions or Sentence-Questions.

1. Word-Questions. These are introduced by the various interrogative
pronouns and adverbs, such as--quis, qui, qualis, quantus, quot, quotiens,
quo, qua, etc. Thus:--

quis venit, _who comes?_ quam diu manebit, _how long will he stay?_

2. Sentence-Questions. These are introduced--

a) By nonne implying the answer 'yes'; as,--

nonne videtis, _do you not see?_

b) By num implying the answer 'no'; as,--

num exspectas, _do you expect?_ (i.e. _you don't expect, do you?_)

c) by the enclitic -ne, appended to the emphatic word (which usually
stands first), and simply asking for information; as,--

videsne, _do you see?_

A question introduced by -ne may receive a special implication from the
context; as,--

sensistine, _did you not perceive?_

d) Sometimes by no special word, particularly in expressions of
_surprise_ or _indignation_; as,--

tu in judicum conspectum venire audes, _do you dare to come into the
presence of the judges?_

3. Rhetorical Questions. These are questions merely in form, being employed
to express an emphatic assertion; as, quis dubitat, _who doubts?_ (_= no
one doubts_).

4. Double Questions. Double Questions are introduced by the following
particles:--

utrum ... an;

-ne ... an;

---- ... an.

If the second member is negative, annon (less often necne) is used.
Examples:--

utrum honestum est an turpe, }
honestumne est an turpe, } _is it honorable or base?_
honestum est an turpe, }
suntne di annon, _are there gods or not?_

a. An was not originally confined to double questions, but introduced
single questions, having the force of -ne, nonne, or num. Traces of this
use survive in classical Latin; as,--

A rebus gerendis abstrahit senectus. Quibus? An eis quae juventute
geruntur et viribus? _Old age (it is alleged) withdraws men from active
pursuits. From what purs
