You can purchase a translation dictionary like this one:
https://www.amazon.com/ENGLISH-CROAT.../dp/B004CRSR1G
and it will become one of the dictionaries you can use with English (as it is free in Kindle Unlimited, I just tried it, it works fine).
If you have a smartphone, you can probably use something like Google or Bing Translate app to translate the English you see on screen.
