Meaning and history
Deryn is a modern Welsh given name taken from aderyn, the Welsh word for “bird,” with the initial vowel omitted in the personal-name form. It is used for more than one gender, though often for girls. The name belongs to a broader Welsh tradition of nature vocabulary in personal names. A notable bearer is Welsh poet and academic Deryn Rees-Jones. Similar-looking names in other languages may have unrelated origins, so the Welsh meaning is context-dependent.
