The Verb.

Tenses.

The VERB in Esperanto has three main Tenses--the Present, Past, and
Future. These are denoted by means of the verbal endings *-as*, *-is*,
and *-os*. Thus, from the root _vid_, see, are formed:

Present. | Past. | Future.
_mi vidas_, I see | _mi vidis_, I saw | _mi vidos_, I shall see

Moods.

Every Esperanto verb has three Moods--the Conditional, the Imperative,
and the Infinitive, which are formed respectively by means of the
endings *-us*, *-u*, and *-i*. Thus:

Conditional. | Imperative. | Infinitive.
_mi vidus_, I should see | _vidu_, see! | _vidi_, to see

The CONDITIONAL Mood is used to express _supposition_; the three Tenses,
on the other hand, are used to express _facts_ or actual happenings.
(For examples, see section "Conjunctions".)

The IMPERATIVE Mood is used to express an order, desire, wish, will,
etc. (See section "Use of Imperative".) Used with the personal pronouns
of the 1st and 2nd persons, this mood corresponds to the English _let_,
used as an expression of a wish. Thus: _mi pensu_, let me think; _li
venu morgaux_, let him come to-morrow; _ili parolu_, let them speak.
