doslovno

1. (of translation, quoting) word for word; verbatim
   Ne prevodi doslovno, nego po smislu. — Don't translate word for word, translate the meaning.
   Ponovio je doslovno ono što sam mu rekla. — He repeated verbatim what I had told him.
2. literally
   Nemoj to shvatiti doslovno, samo sam se šalio. — Don't take it literally, I was just joking.
   Nije to metafora, on je doslovno spavao na ulici. — It's not a metaphor, he literally slept on the street.

In everyday speech "bukvalno" is more common; both words are also often used just for emphasis (doslovno sam umrla od smeha = I literally died laughing).
