. . . and how do you say it in Bangla?

 Galad Ilzaam”(Hindi word) I said to a friend during one of our phone conversation. Then I asked her what “galadh Ilzaam” was in Bangla, as I pondered. There was this awkward silence followed by “ ummm . . .ahhh . . .hmm” and finally “I don’t know”.
Before I start, I have to admit my Bangla vocabulary is worse than that of a 5^th grade student and that’s something I am really ashamed of. That is not the point though; the point is that there are a lot of Bengalis like me who often use these catchy Hindi terms in their daily conversations thanks to Hindi movies and soap operas. I have noticed this especially among the children, they watch cartoons in Hindi and they pick up the phrases and terms very easily. I have nothing against it, in fact I think learning new language is great but we have to keep in mind that we shouldn’t let another language replace our mother tongue.
(By the way, galad ilzaam means false accusation in English but I still don’t have a clue how to say it in Bangla.)
