Ch 5 · Lesson 11

Kiam: the tense that is really true

, : when he comes, said in the future because it is in the future. The same goes for , and .

The short version

takes the tense that is really true

, .

When he comes, I will tell him.
Why?

English says when he comes, a present, about something that has not happened yet. Esperanto says , because the coming is in the future. Every verb carries its real time, so the same goes for , and : , , I will wait until you come.

kiam and the real tense

tense endingWhat do the colours mean?

Time clauses take the tense that is actually true, measured from the main verb:

TimeEsperantoEnglish
past , .When I came, he was sleeping.
future , .When he comes, I will tell him.

English says when he comes, a present, about something that has not happened. Esperanto says , because it is in the future. Casual speech sometimes uses for a future too, but the careful form, and the one to learn, is .

The same principle runs through clauses after a past verb:

  • , . - He said he was ill. (he said: I am ill)
  • , . - He said he had been ill. (he said: I was ill)

There is no English-style shift backwards: reported speech has the whole rule.

The other time words work the same way:

WordEnglishExample
while , .
after , .
until , .
before , .

takes a plain infinitive when the subject stays the same: , . - I ate before leaving.
