unu, one. du, two. tri, three. kvar, four. kvin, five. ses, six. |
sep, seven. ok, eight. naŭ, nine. dek, ten. dek unu, eleven. dek du, twelve. |
137. With the exception of unu, none of the cardinals may receive the plural ending -j or the accusative ending -n. That is, they are invariable in form. Unuj may be used to mean some in contrast to aliaj, others:
Unuj marŝis, aliaj kuris, some walked, others ran.
Mi prenis unujn kaj lasis la aliajn, I took some and left the others.
138. The preposition el is used after numeral adjectives expressing a number out of some larger number or quantity:
Ses el la knaboj venis, six of the boys came.
Ok el tiuj libroj estas la miaj, eight of those books are mine.
El tiuj ĉapeloj mi ŝatas nur unu, of those hats I like only one.
The cardinal unu must not be used in the sense of the English pronominal "one," as in I am searching for a book, but not the one on the table, which should be translated Mi serĉas libron, sed ne tiun sur la tablo.
THE ACCUSATIVE OF MEASURE.
139. A substantive in the accusative case may be used, instead of a prepositional phrase or an adverb, not only to express measure (duration) of time (91), but also to express measure of weight, price, length, etc.:
Li marŝis dek unu mejlojn, he walked eleven miles.
La parko estas larĝa tri mejlojn, kaj longa kvar mejlojn, the park is three miles wide and four miles long.
La tablo pezas dek du funtojn, the table weighs (is heavy) twelve pounds.
