Eider

Eider is a Basque feminine name related to Eder, meaning “beautiful.” Separately, English eider names a group of sea ducks known for their insulating down. The bird word and the Basque name do not share a single origin, so either can be the intended connection without being combined into one translation.

The name is now also used for boys in the United States, illustrating how usage can differ between countries and traditions. Pronunciation deserves attention: the Basque name and the English bird word need not sound identical. Families choosing Eider for its nature connection may favor the English reading, while those honoring Basque heritage may prefer that language’s established name and pronunciation.
