What languages does Bjarni Tryggvason speak?

Bjarni Tryggvason, the Viking explorer who is credited with discovering North America, lived in the 10th century. There is no record of what languages he spoke, but we can make some educated guesses:

* Old Norse: This was the common language of the Vikings, and it is likely that Bjarni spoke it.

* Other Scandinavian languages: There's a chance he spoke other Scandinavian languages like Old Swedish or Old Danish, as communication between these groups was relatively common.

* Local languages: If Bjarni had traveled to other parts of Europe or interacted with different cultures, he might have learned additional languages. However, there's no evidence to support this.

It's important to note that these are just possibilities based on his historical context. We cannot definitively say what languages Bjarni Tryggvason spoke.
