A sin, maybe; in the dining board I cannot be satisfied! (10)
I believe the answer is:
insatiable
'satisfied' is the definition.
Both the answer and definition are adjectives. Perhaps they are linked in a way I don't understand?
'a sin maybe in the dining board i cannot' is the wordplay.
I cannot really understand how this works, but
'a' is present in the answer.
an anagram of 'sin' is 'ins' which is within the answer.
'maybe' could be 'i' (I've seen this in other clues) and 'i' is found in the answer.
'the' could be 't' (the is pronounced as a 't' sound in some dialects) and 't' is present in the answer.
'i' could be 'a' and 'a' is present in the answer.
This may be the basis of the clue (or it may be nonsense).
'be' acts as a link.
Can you help me to learn more?
(Other definitions for insatiable that I've seen before include "Never satisfied" , "Unquenchable" , "that could describe monstrous appetite" , "can't get enough of it" , "Having desires impossible to satisfy" .)
