bay
Bay rhymes with say not by..by....which if you mean goodbye, then the word is spelt bye bye...
As far as I am aware there is no word which ryhmes.
The Welsh word "fyd" rhymes with "byd."
beh maer byd yn ticlo
ledled y byd
Y byd Golwg
Llawenydd i'r byd
"Byd byd byd heb wybodaeth" is Welsh for "World world world without knowledge." It is a phrase used to emphasize the importance of acquiring knowledge and information in life.
'caru chi i gyd y byd'
flag-banner half-hanner
Mae'n ddrwg gennym dim byd yn y depo.
TLUSS-nee (rhymes with "PLUS-knee")
It is difficult for one to tell from this question what word is being asked about. Byd is not a word in the English language. The correct spelling could be bid, or possibly bide.
