Some rays of light seen in headland fire (6)
I believe the answer is:
spirit
'fire' is the definition.
(thesaurus)
'some rays of light seen in headland' is the wordplay.
'some rays of light' becomes 'ri' (I can't explain this - if you can you should believe this answer much more).
'seen in' means one lot of letters goes inside another.
'headland' becomes 'spit' (I have seen 'Narrow headland ' mean 'spit' so perhaps 'headland' could also mean 'spit').
'ri' inserted into 'spit' is 'SPIRIT'.
Can you help me to learn more?
(Other definitions for spirit that I've seen before include "The non-physical part of a person" , "Ghost or strong drink" , "Life-giving force" , "Brandy" , "Courage, determination" .)
