"Dw i eisiau bwydo'r ci."

Translation: I want to feed the dog.

[pablopublico]

"Bwyd" (food) comes ultimately from Proto-Indo-European "*gʷeyh₃tom", from "*gʷeyh₃-" (to live), of which also descend Welsh "byw" (to live; alive) and "bywyd" (life), Irish "bia" (food; substance) and "beatha" (life), English "quick", Latin "vīta" (life [whence Romance "vida/vie/viață"]) and "vivus" (alive [Romance "vivo/vif/viu/bibu"]), Ancient Greek "βῐ́ος/βίοτος" (bíos/bíotos, “life” [as in biology, biosphere and bionic]) and "ζῷον" (zôion, "animal" [as in zoology) , Russian "живот" (život, "belly; (archaic) life"), Lithuanian "gyvatà" (“life”), Sanskrit "जीवित" (jīvitá, "living; life"), Avestan "gayo" ((accusative "ǰyātum") "life"), etc.

[tinmur]

As "the dog" is "y ci" how does it become "..bwydo'r ci" and not "bwydo y ci"

[Julianbark6]

As in the earlier units, "y" becomes "yr" before a vowel and "'r" after a vowel
