Still likely to be gutted on a regular basis (6)
I believe the answer is:
evenly
'on a regular basis' is the definition.
Both the answer and definition are adverbs. Maybe there's an association between them I don't understand?
'still likely to be gutted' is the wordplay.
'still' becomes 'even' (synonyms).
'to be gutted' means to remove the middle letters (to gut something is to remove its insides).
'likely' with its middle taken out is 'ly'.
'even'+'ly'='EVENLY'
Can you help me to learn more?
(Other definitions for evenly that I've seen before include "In measured or level manner" , "Equally or smoothly" , "in a uniform way" , "In measured or smooth manner" , "On an equal basis" .)
