"Yr wyf fi yn ddrwg", to me, would be "I am bad", meaning "I am sick".

"Y mae drwg i mi", on the other hand is, in Saesnaeg "there is bad with me".

I have found, when using the Google Saesneg i Cymraeg, thst it pays little if any heed to the necessary consonant mutations characteristic of Cymraeg.

e.g "Cymraeg" Gymraeg" "Chymraeg" ; NGhymraeg".

"Plaid" ; "Phlaid" "Blaid" Mhlaid" ;

"Teulu" ; Deulu".
