28. The infinitive is a form of the verb which expresses merely the
general idea of the action or condition indicated, and has some of the
characteristics of a noun. The ending of the infinitive is "-i", as
"kuri", to run, "esti", to be, "havi", to have.
29. An infinitive used to complete the meaning of another verb, serving
as a direct object to a transitive verb, is called a "complementary
infinitive". If the complementary infinitive is from a transitive verb,
it may itself have a direct object:
La knabo volas kuri, the boy wishes to run.
Birdoj sxatas kanti, birds like to sing.
La knabo volas havi cxevalon, the boy wishes to have a horse.
Ili volas trovi florojn, they wish to find flowers.
