it might not rhyme... but
purple might go well with gurgle
orange with ranch...wrench
siliver...i suppose you meant silver....that goes well with liver
and
month....well....hmm yeah....that one is ugly...it's a very ugly word on it own
I knew "orange" was an impossible one (quite frequent joke in popular culture) but didn't know about the others. Then again, I'm not a native English speaker.
