'Andorra' originates from uncertain regional roots; one commonly cited possibility is from Basque, specifically the element 'andurrial' meaning 'shrubland' or 'bushy place'.

'Andorra' appears in medieval records in forms very close to the modern name (Medieval Latin/Catalan 'Andorra') and gradually stabilized as the modern country name 'Andorra'.

Initially it likely referred to a local geographic description (e.g., 'shrub-covered land'), but over time it became the proper name identifying the territory and later the independent principality 'Andorra'.
