Lay to rest? With quicklime ban it's everlasting (12)
I believe the answer is:
interminable
'everlasting' is the definition.
(thesaurus)
'lay to rest? with quicklime ban' is the wordplay.
I cannot really understand how this works, but
an anagram of 'ban' is 'nab' which is present in the answer.
'lay to rest?' could be 'inter' (synonyms) and 'inter' is located in the answer.
The remaining letters 'mile' is a valid word which might be clued in a way I don't see.
This may be the basis of the clue (or it may be nonsense).
'it's' acts as a link.
Can you help me to learn more?
(Other definitions for interminable that I've seen before include "Without end" , "Seeming likely to go on for ever" , "Such a long wait" , "Tedious" , "Long drawn-out" .)
