'andorran' originates from the country name 'Andorra', with the English suffix '-an' added to denote origin or relation.

'Andorra' was adopted into English from Catalan 'Andorra', and the suffix '-an' was added to form 'Andorran', meaning someone or something from Andorra.

Initially, it meant 'a person from Andorra' or 'relating to Andorra', and this meaning has remained unchanged in modern usage.
