Any app to show the definition of the word when i highlight it ?

[FaiqT]

Hi, this my second thread in AC, so i don't know if i'm posting this in the right section, apologies if not.
I do use BBC News app to read news, as english is not my native language sometimes there are some words that i don't know what they mean, everytime i have to use google translate to find its definition and it consumes time to swith between apps, i need an app to show me the definition of the word when i highlight it (or doubletap, anything within the app) so i won't have to swap between apps everytime and get the definition within the page or app im on. Post them here if you use any, cheers.
