THE PRESENT ACTIVE PARTICIPLE.

108. A participle is a "verbal adjective", as in "a "crying" child."
It agrees like other adjectives with the word modified (19, 24). The
participle from a transitive verb (22) may take a direct object, and a
participle expressing motion may be followed by an accusative indicating
direction of motion (46). The present active participle, expressing what
the word modified "is doing", ends in "-anta," as "vidanta", seeing,
"iranta", going:

La ploranta infano volas dormi. The crying child wishes to sleep.
Mi vidas la falantajn foliojn, I see the falling leaves.
Kiu estas la virino acxetanta ovojn? Who is the woman buying eggs?
Mi parolis al la viroj irantaj vilagxon.
I talked to the men (who were) going toward the village.


COMPOUND TENSES.

109. A participle may be used predicatively with a form of "esti", as
"Mi estas demandanta", I am asking, "La viro estas acxetanta", the man
is buying. Such combinations are called "compound tenses", in contrast
to the "simple" or "aoristic" tenses.

[Footnote: An aoristic tense consists of but one word (ending in
"-as", "-os", etc.) and expresses an act or state as a whole, without
