Etymology
Derived from, from. Matasović, however, is confused at how the -o- in became -a- in Gaulish and Brythonic. However, Schrijver believes that in Brythonic, sequences of *wo regularly split into *wa and *wo depending on whether the *w was lenited; in this case, the vowel in the Brythonic descendants would be generalized from the lenited form. The Gaulish conversion of *wo to ua is regular.
