Being out of line, Fred gets very heated! (5)
I believe the answer is:
fried
'very heated' is the definition.
'fried' can be an answer for 'heated' (thesaurus). I am not sure about the 'very' bit.
'being out of line fred' is the wordplay.
'being' becomes 'fry' (fry is a kind of being).
'out of' means to remove the last letter (I've seen 'out' mean this).
'line fred' becomes 'ied' (I can't explain this - if you can you should believe this answer much more).
'fry' with its final letter removed is 'fr'.
'fr'+'ied'='FRIED'
'gets' is the link.
Can you help me to learn more?
(Other definitions for fried that I've seen before include "Cooked on a hot surface" , "Cooked in fat" , "Cooked in oil" , "Cooked in oil/fat" , "Such as cooking chips" .)
