Once again, warm the ear somehow (6)
I believe the answer is:
reheat
'once again warm' is the definition.
'reheat' can be an answer for 'warm' (thesaurus). I am not sure about the 'once again' bit.
'the ear somehow' is the wordplay.
'somehow' is an anagram indicator.
'the'+'ear'='theear'
'theear' is an anagram of 'REHEAT'.
Can you help me to learn more?
(Other definitions for reheat that I've seen before include "Cook again" , "Bring back to the boil, for instance" , "Process increasing jet engine thrust" , "Jet engine afterburner" , "Method of getting extra power from jet engine" .)
