Attraction of every part of a Yorkshire river (6)
I believe the answer is:
allure
'attraction' is the definition.
(I know that allure is a type of attraction)
'every part of a yorkshire river' is the wordplay.
'every' becomes 'all' (similar in meaning).
'part of a yorkshire river' becomes 'ure' (I can't explain this - if you can you should give a lot more credence to this answer).
'all'+'ure'='ALLURE'
'of' acts as a link.
Can you help me to learn more?
(Other definitions for allure that I've seen before include "Enchanting attractiveness" , "Seduce" , "Attraction, appeal" , "Entice; appeal" , "Attractiveness, glamour" .)
