I've learned that if you're translating a name into Japanese you have to translate it by the sound. I want to translate the name "Tymoteusz". I think the name itself is Greek but the writing is Polish, however it's not Japanese so I need katakana. I started translating.
The first sound is a "t" and then "y" (you read the "y" in polish ⟨ɘ⟩). There is no sound in Japanese that sounds like this so I used チ.
Then the next sounds are pretty easy. First just a モ. Then テ. And then ウ.
So I got チモテウ. Now I need the last sound. You read "sz" like a English "sh" (⟨ʃ⟩). I've heard Japanese People using this soind, but I have no Idea how to write it. Can someone help me?
How to write ⟨ʃ⟩ in Japanese? And is my translation correct (all sounds without IPA sound like the Japanese ones)?
