Loathing of element (not sulphur) (5)
I believe the answer is:
odium
'loathing' is the definition.
(synonyms)
'element not sulphur' is the wordplay.
I cannot quite understand how this works, but
'element' could be 'u' (U is an example) and 'u' is located in the answer.
'not' could be 'o' (I've seen this in other clues) and 'o' is found within the answer.
The remaining letters 'dim' is a valid word which might be clued in a way I don't understand.
This may be the basis of the clue (or it may be nonsense).
'of' is the link.
Can you help me to learn more?
(Other definitions for odium that I've seen before include "Offensiveness" , "Dislike of someone, or something hated" , "shame!" , "that would cause disgust" , "disapprobation" .)
