Deity just starts cooking tripe (7)
I believe the answer is:
jupiter
'deity' is the definition.
(Jupiter is an example)
'starts cooking tripe' is the wordplay.
'starts' becomes 'ju' (I can't justify this - if you can you should give a lot more credence to this answer).
'cooking' indicates anagramming the letters (cook can mean to falsify or distort).
'tripe' with letters rearranged gives 'piter'.
'ju'+'piter'='JUPITER'
'just' is the link.
Can you help me to learn more?
(Other definitions for jupiter that I've seen before include "Largest planet in our solar system" , "celestial body" , "Large planet" , "to which Tom Towers contributed" , "Chief of the Gods, by Jove" .)
