60. The demonstrative pronoun (and pronominal adjective) meaning "this"
is formed by using with "tiu" (56) the word "cxi", which expresses the
general idea of nearness or proximity. (Consequently the literal meaning
of "cxi tiu" is "that one nearby", "that one here".) The word "cxi" may
either precede or follow the pronoun:
Cxi tiu estas la mia, this is mine.
Mi vidis cxi tiun, I saw this one.
Cxu vi volas tiujn cxi? Do you wish these?
Cxi tiu knabino estas mia fratino, this girl is my sister.
Mi vidis cxi tiujn cxapelojn, I saw these hats.
Cxi tiuj amikoj promenos, these friends will take a walk.
61. The words "tiu" and "cxi tiu" may be used to distinguish between
persons or things "previously" mentioned and "just" mentioned:
Gertrude kaj Mario estas en la parko.
Tiu rigardas la florojn, cxi tiu kolektas ilin.
Gertrude and Mary are in the park.
The former (that one) looks at the flowers,
the latter (this one) gathers them.
