Questions & Answers about Ĉiufoje, kiam la tajloro prenas mezuron, li skribas ĝin.
Ĉiufoje means every time or each time.
It is built from:
- ĉiu = every, each
- foje = time, occasion
So ĉiufoje literally means on every occasion. In this sentence, it introduces a repeated action: every time the tailor takes a measurement, he writes it down.
The comma separates the main idea from the time clause introduced by kiam.
The structure is:
- Ĉiufoje = every time
- kiam la tajloro prenas mezuron = when the tailor takes a measurement
- li skribas ĝin = he writes it
Esperanto often uses commas a bit more regularly than English, especially before subordinate clauses like one introduced by kiam.
