Correct spelling for the English word "Orisont" is [ˈɒɹɪsˌɒnt], [ˈɒɹɪsˌɒnt], [ˈɒ_ɹ_ɪ_s_ˌɒ_n_t] (IPA phonetic alphabet).
The word "Orisont" does not have an established etymology as it appears to be a variation or a misspelling of the word "horizon". However, "horizon" has its roots in the Middle French word "horizon" which came from the Latin word "horizon", meaning "the line where the earth and sky meet". This Latin word, in turn, was derived from the Greek word "horizōn" which means "limit" or "boundary".
