267. The co-ordinating conjunction is sometimes omitted.
Examples.—Li venis, li vidis, li venkis = He came, he saw, he conquered! Vi iros, Johano restos tie ĉi = You will go, John will remain here.
268. Conjunctions and adverbs.—Some English words are sometimes adverbs and sometimes conjunctions, more especially those introducing clauses of time or place. Some are also prepositions as well as conjunctions and adverbs, and care must be taken to use the correct Esperanto words in such cases. For instance, in English "before," "after," and "since" are prepositions, adverbs, or conjunctions.
Before (prep.) = Antaŭ.
Example.—Li staris antaŭ la reĝo = He stood before the king.
Before (adv.) = Antaŭe.
Example.—La reĝo neniam lin vidis antaŭe = The king never saw him before.
Before (conj.) = Antaŭ ol.
Example.—Pripensu antaŭ ol paroli = Reflect before speaking.
