Etymology
The origin of Icovellauna’s name is uncertain. Some scholars have connected it to the Indo-European *iēk- or “heal”; others have attempted to tie it to Proto-Celtic terms for “water” such as *iska although this seems a less likely link. The second part of the name has been connected to the Proto-Celtic *walo or “chief,” suggesting a link between the goddess and civil or military authority.
