[protheus]

I know about the romanji meaning, the kanji (cuneiform writting adapted from chinese), I'm at page 30 in the Jappanesse grammar Guide, those were clear, but this wasn't, the use of both katakana and hiragana in the same one. They were explained separate, that confused me.
Kanji, I already understood that replaces words, meanings (and even more) in any written type, so that implies it is being used everywhere (except in romanji).
