Sut mae, pawb.
I'm not sure if it's been suggested before but as my studies in OBOD and Welsh continue I'd like to use more Welsh in my rituals(*) etc...
So I thought that maybe we could share a common dictionary that we could all add to to help promote the idea.
I'll start off with...
perfformio - to perform
myfyrio - to meditate (vn)
myfyrdod (m, -au) - meditation
corff (m, cyrff) - body
golau (m, goleuadau) - light
cyflawni - to carry out (vn)
darganfyddiad (m, -au) - discovery
breuddwyd (f, -ion) - dream
defod (f, -au) - rite, ceremony
Please feel free to add and or correct.
*This is a personal thing and is not motivated by any thoughts that only "Celtic people" or people who speak Celtic languages can be involved in druidry.
