Which language do you prefer to read books in? English or Arabic? Why?

I read extensively in both languages. Although, I am more inclined to Arabic and more comfortable and confident when speaking it because it was the medium of my learning from my primary education to tertiary. Nevertheless, I pay much attention on my skills in English in a bid to improving it and making it as good as my skills in Arabic.

I prefer English language and Arabic language. Thanks for the invitation

well, Both starting from Arabic. Why? since English is nowadays language and its tichnecally the world language, i would like to keep my mother language. but of course reading books in English improvs my language learning new words. 

English because i am not expert in Arabic

we prefer more English as it improves our language and it is international language it is simple and lucid through it people can communicate to the people of different countries

English, I'm still learning the arabic literature.

English, because I am more fluent in Eglish compare to Arabic

I read English since that's my native language.  

Actually both , although I prefer to read books in English as it's very helpful for improving my English 

Being an English trainer-teacher besides Arabian I have to read books in English and Arabic . I am used to even analysing them
