Översättning - Esperanto-Engelska - Por studi la ceremoniojn ni komencis studi unue...

at first --> first

Good. What does "them" refer to - the ceremonies or the Iranians? I don't understand that part.

Neither - "them" is intended to refer to "Iranians' ancient thinking and their geography and natural state". Would "to the point one may use these" solve that ambiguity (which comes from the source text)?

Sorry - it still doesn't make sense in English - what is "to the point"? Do you mean "until" or "so that"?

Also, it should be "began", not "have begun".

Is it correct now?

I'm not sure. I don't understand what "until one may use them" means - does it mean that that is when we will stop studying them? Can you translate "ĝis eble oni povus uzi ilin" word for word (including cases and persons) for me?

Well... here it goes:

ĝis = until
eble = maybe
oni = one (undefinite subject)
povus = to be able to (conditional mood)
uzi = to use (infinitive)
ilin = them (3rd person plural, accusative case)

(I don't think it helps that much, though... )

Wow - thanks, goncin, but as you say, it doesn't really solve the problem.

Do you think it means something like "to the point where the studies were usable (by other people)"?

Yep. It's what I wanted to mean when I first wrote "to the point one could use them"...

OK - I edited with that and have put a note below. I'll put this one to a vote.

Sorry - on re-read, this just doesn't work, because the word "studies" doesn't appear in the English, so the English reader assumes that some other plural noun is the referent. I will re-edit.

I'm trying to help alireza with these texts in Esperanto, but the texts in Esperanto simply don't help me... stevo (another Esperanto expert) has done one of these texts, not more successful than me...
