Don’t be surprised if she’s Swedish (5)

'don't' is the definition.
Both the definition and answer are singular nouns.
Perhaps there's a link between them I don't understand?

'surprised if she's swedish' is the wordplay.
I cannot really understand how this works, but
'she' could be 'elga' and 'elga' is located in the answer.
A single letter 'h' remains which might be clued in a way I don't see.
This may be the basis of clue (or it may be nonsense).

'be' is the link.

Can you help me to learn more?
