> I know, it's irrelevant to the subject, but if you're really curious, I can say, that sound 'v' on the end of word in Russian orfography (?? spelling?) replaces by g, e.g.:

Orthography I think is the word.

>And, BTW, the sound ã (g) in Russian sounds differently, than g in English.

Not always. Usually. The Russian hard "g" sound is just like "gg" in English, as in "gagging". A glottal sound. Almost like there was a hard sign after it (tvyordi znyak?). But, generally, the "g" in both Russian and English is a chameleon: It changes dramatically based on placement. Funny, it's that way in Spanish as well. A hard "g" sometimes, as in "gordo" (fat) or a syllibant sound as in "pagina" (page).

Fun with language, huh?
