Husband stupidly cheating claims love is intense (4-6)
I believe the answer is:
high-octane
'intense' is the definition.
Both the definition and answer are adjectives. Perhaps they are linked in a way I don't understand?
'husband stupidly cheating claims love' is the wordplay.
I cannot really understand how this works, but
'husband' could be 'h' (abbreviation) and 'h' is found in the answer.
'love' could be 'o' (love means zero in tennis) and 'o' is found within the answer.
an anagram of 'cheating' is 'ighctane' which is present in the left over letters.
No letters remain.
This may be the basis of the clue (or it may be nonsense).
'is' acts as a link.
Can you help me to learn more?
(Another definition for high-octane that I've seen is " Powerful and dynamic".)
