purple, ninja, diamond, liquid, engine, comment, iron... there's loads!
==============================
I've just been thinking about this one actually... there's a catch to this question, do you mean a refractory rhyme or a perfect rhyme (an exact match of all sounds after the stressed vowel?)
If it's a perfect rhyme, there's technically only one... 'of' but north of say, Birmingham, it could be argued that words like 'love' or 'dove' will rhyme with it because of the stress pattern of local pronunciation so I guess that rules out perfect rhymes.
Yes, I know I need to get a life!
