Hello,
I'd like to ask a quick question about several of the pronunciations for certain kana.
Some kana have 2 romanizations and I was wondering when it would be pronounced which way like si/ shi, ti/chi, tu/tsu, and hu/fu (This one I don't really get.) Another example I don't get was じ being either zi or ji and then ぢ di or ji and then ぢゃ and じゃ columns have them as zya/ja etc and dya/ja etc. I'm confused as to how you'd know when ja/ji/ju/jo would be used since they each can be 2 kana.
