You have a good point. However, I am conservative on Type 4 fu'ivla in that I believe
they should only be used for words that are internationally recognized. 'Ramadan'
is recognized virtually everywhere, whereas Eid ul Fitr is not. I'm tempted to
suggest musysezyfantyfamnunsla - but that's just too long!
I think it's best to take a hint from Moslems themselves. What do non-Arabic-speaking Moslems call these holiday? Do American Moslems call it "Eid-ul-Fitr" or do they call it "breaking the fast day"? I believe the former, so this is what Lojban should do as well.
I do undersatnd there is no consensus on this. But lojban is for everybody. 'International recognized' does not mean American Moslems. For me it means also recognition by Japanese Buddhists, Brazilian atheists, German agnostics etc.
