'astrid' originates from Old Norse, specifically the name 'Ástríðr', where 'áss' meant 'god' and 'fríðr' meant 'beautiful' or 'beloved'.

'Ástríðr' changed through Old Norse and Old Scandinavian forms into medieval Scandinavian names such as 'Astrid' and was later borrowed into modern English as a female given name.

Initially it meant 'god-beautiful' or 'divinely beautiful' in Old Norse; over time it has remained primarily a feminine personal name carrying that core sense rather than a literal compound meaning.
