Mystery Monday: Fisa

If you have any thoughts about the name’s origin, other variants it might be related to, other examples of its use, etc., please share them in the comments! If you wish to browse other Mystery Monday names, there is an index.

12th-century France is full of lovely, unusual feminine names, and one of them is today’s Mystery Monday name.

There is a Latin explanation for what it might be: fisa is a perfect passive participle of Latin fido ‘trust, have confidence (in)’. It is possible that this is the root of the name, but it would certainly be an unusual construction.

Does anyone have any thoughts? Any alternative explanations (probably, Germanic)? Please share in the comments!
