23. The person or thing acted upon is called the "direct object" of
a transitive verb, and is given the ending "-n". This is called the
accusative ending; and the word to which it is attached is said to be
in the "accusative case":
La viro havas segxon, the man has a chair.
La knabo trovas florojn, the boy finds flowers.
[Footnote: The ending "-n" follows the ending "-j", if the word to be
put in the accusative case is in the plural number.]
24. An attributive adjective modifying a noun in the accusative case is
made to agree in case, by addition of the same accusative ending "-n".
This prevents any doubt as to which of two or more nouns in a sentence
is modified by the adjective, and permits of variation in the order of
the words:
La knabo trovas belan floron, the boy finds a beautiful flower.
Florojn belajn la viro havas, the man has beautiful flowers.
La viro havas grandan segxon, the man has a large chair.
Rugxan rozon la knabo havas, the boy has a red rose.
25. A predicate adjective or noun (19) is never in the accusative case,
nor is the accusative ending ever attached to the article, which is
invariable as stated in 18.
