240. A conditional sentence consists of two parts, an "assumption" and
a "conclusion". The assumption is a clause (introduced usually by the
conjunction "se", "if") which assumes something as true or realized. The
conclusion is a statement whose truth or realization depends upon the
truth or realization of the assumption. "Factual conditions" (conditions
of fact) may deal with the present, past or future time:
Se li vidas tion, li ploras,
if he sees that, he weeps (is weeping).
Se li vidis tion, li ploris,
if he saw that, he wept.
Li ploros, se li vidos tion,
he will weep, if he sees that.
Se li venis hieraux, li foriros morgaux,
if he came yesterday, he will go away tomorrow.
Se li estas vidinta tion, li nun ploras,
if he has seen that, he now is weeping.
Se tio estas vidota, li estas punota,
if that is going to be seen, he is going to be punished.
Se li estas kaptita, li estos jam punita,
if he has been captured, he will already have been punished.
