Dù

The name Dù (or Dubh) originates from the Old Irish word 'dub' meaning 'black' or 'dark'. It was historically used as a descriptive epithet for individuals with dark hair, complexion, or even a somber disposition. Over time, it evolved into a given name and a common element in surnames, particularly in Scotland and Ireland.

Its usage as a given name is relatively rare in modern times, often appearing as a component in more complex names or as a nickname. The simplicity and directness of its meaning connect it to a very ancient linguistic root, reflecting a time when names were often direct descriptors of physical characteristics or personality traits.
