The inherent nature in this delicatessen certainly emerges (7)
I believe the answer is:
essence
'the inherent nature' is the definition.
'essence' can be an answer for 'nature' (I've seen this before). I'm unsure of the 'the inherent' bit.
'this delicatessen certainly emerges' is the wordplay.
'ESSENCE' is hidden within the letters.
However, I'm unsure how this is indicated.
'in' acts as a link.
Can you help me to learn more?
(Other definitions for essence that I've seen before include "Concentration; nub" , "Distinctive inner nature of person or thing" , "Concentrated liquid flavouring" , "Plant extract or concentrate" , "Soul" .)
