given for the use of final "n" is, that "n" is added to nouns and
pronouns (a) in the Accusative Case (the direct object), (b) when the
preposition is omitted. The explanation given above seems to me,
however, to be much simpler. (ii.). Another use of final "n" is given
later [Lesson 12, Lesson 26] ]

When the noun takes "n", any adjective which belongs to it must also
take "n", as, "Li donas al mi belan rugxan floron", He gives me a
beautiful red flower. "Li donas al mi belajn rugxajn florojn", He gives
me beautiful red flowers.
