תרגום - פורטוגזית ברזילאית-רומנית - Deus é Amor

I search in Romanian on-line bible , so i found: 1 John 4:8-16 is : 8 Cine nu iubeşte, n'a cunoscut pe Dumnezeu; pentrucă "Dumnezeu este dragoste."
I can't understand iubire , Lubire ? what is the first caps "i" , small "L"symbol? and "Dragoste" is Love what is different?
