Some 'yep', only on the contrary? (4)
I believe the answer is:
nope
'some yep only on the contrary?' is the definition.
I can't judge whether this definition defines the answer.
'some yep only on the contrary?' is the wordplay.
'some' indicates a hidden word (some parts of the word are used).
'on the contrary?' says the letters should be written backwards (letters in the opposite or contrary direction).
'epon' is hidden within 'yep only'.
'epon' reversed gives 'NOPE'.
Can you help me to learn more?
(Other definitions for nope that I've seen before include "I'm afraid not" , "not with stress" , "I don't think so!" , "Emphatically not!" , "You must be joking" .)
