Buccaneer loses head in anger (5)
I believe the answer is:
irate
'buccaneer loses head in anger' is the definition.
I can't judge whether this defines the answer.
'buccaneer loses head' is the wordplay.
'buccaneer' becomes 'pirate' (historical term for a pirate).
'loses head' means to remove the first letter.
'pirate' with its first letter taken away is 'IRATE'.
Can you help me to learn more?
(Other definitions for irate that I've seen before include "Infuriated" , "Indignant, angry" , "ranting" , "Magical rod" , "I tear away, being annoyed" .)
