Popular delicacy not touched (6)
I believe the answer is:
intact
'not touched' is the definition.
The answer and definition are different parts of speech. However, past participle verbs and adjectives can occasionally define each other.
'popular delicacy' is the wordplay.
'popular' becomes 'in' (something that's 'in' is fashionable).
'delicacy' becomes 'tact' (I've seen this in another clue).
'in'+'tact'='INTACT'
Can you help me to learn more?
(Other definitions for intact that I've seen before include "Whole and unharmed" , "Flawless" , "Unbroken and unimpaired" , "Entire and complete" , "Unbroken - sound" .)
