I would recommend getting an eReader like a kindle. Because there is a built in dictionary where you can directly translate any of the words from English to your language.

It also has the English Oxford dictionary where you can build up your vocabulary flash card.

I would recommend even start with some children or young adult fiction (where the language is easier) just so you get the hang of the language and then you can progressively work towards harder books.

I am ESL as well and that’s how I progress (though I started when I was a kid so it was natural for me to start with Children and YA books).

Good luck!
