I can see how this phrase confused you, it took me ages to write down the exact derivation of the meaning. Byddwn - Let us be (Yes, it's not in my dictionary as well, I must get a bigger one! It's from 'bod'=be if that's any help) Gyfeillion - friends. Soft mutation of Cyfeillion fel - so ("fel" can mean many things) na - no dde^l - to come (from dod) rhyfel - War mwy - more so if we play around with the word order, we get: Let us be friends, so war comes no more. Or to put it into modern context: Make love not war (man) There's actually something poetic in the phrase in Welsh, but there's no Cynghanedd in there as far as I can see. Oh sorry, Cynghanedd is a poetry form in Welsh, the formation of each line in a poem sticks to fairly rigid rules. Does anybody out there have a list of the rules? I can't remember them. Mind you I never took much notice in my Welsh lessons, as far as I was concerned, I could speak it, and who gave a toss about minor grammatical points. (But I digress). Hwyl Chris
