I passed over sin with Romeo, to give an example (10)
I believe the answer is:
illustrate
'example' is the definition.
(thesaurus)
'i passed over sin with romeo to give an' is the wordplay.
I cannot really see how this works, but
'i' could be 'a' and 'a' is present in the answer.
'sin' could be 'lust' (lust is one of the seven deadly sins) and 'lust' is present in the answer.
'romeo' could be 'r' (phonetic alphabet: alpha, bravo, charlie etc.) and 'r' is present in the answer.
'an' could be 'i' (Roman numeral for one) and 'i' is located in the answer.
The remaining letters 'lte' is a valid word which might be clued in a way I don't understand.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for illustrate that I've seen before include "Explain with pictures" , "Ornament" , "Give as example" , "picture" , "Exemplify" .)
