if anyone can speak cypriot greek, can they please tell me how you would approximate a spelling in greek, of the phrase that sounds like "indan pwnei re;" meaning "what you saying?"
in cypriot greek there is an expression <<Ίνταν πόνειν ρε;>> it means roughly "hey whatchya sayin?"....but is this the best approximation in greek script??

For example, which letter (or letters) would you substitute for j? There is no j sound in the classic Attic pronunciation of Greek. What would you substitute <<<OR>>> what letter combination would you use to show these sounds? Please help!

Why do we learn about greek gods in English? thx!!<3

How would I convert specific compounds into their formula and vice versa??

examples:
Dichlorine Heptaoxide (<-turned into formula)
P(4)S(3) (<-turned into compound)

I know how to convert it without using the Greek names, so the 'Di', 'Hexi' and 'Tri' are throwing me off.
