Dylan (English)

Where does "Dylan" come from?

The English given name Dylan comes from Welsh[1]. In Welsh mythology, the name derives from Welsh elements including 'dy-' meaning 'to, of' and 'llanw' meaning 'tide'[1][2]. These Welsh roots trace ultimately back to the Proto-Indo-European base '*pleh₁-' meaning 'to fill'[3]. It may also be interpreted from Celtic origins meaning 'son of the sea' or 'born from the ocean'[1].

Open questions

• The exact derivation from Celtic meaning son of the sea or born from the ocean remains a possible rather than definitive interpretation. [1]
