Good man's boat wrecked around Beachy Head (5)
I believe the answer is:
abbot
'good man's' is the definition.
'Abbot' can be an answer for 'man's' (I have seen 'Religious man' mean 'abbot' so perhaps 'man' could also mean 'abbot'). I'm not sure about the 'good' bit.
'boat wrecked around beachy head' is the wordplay.
'wrecked' is an anagram indicator.
'around' indicates putting letters inside.
'head' indicates taking the first letters.
The first letter of 'beachy' is 'b'.
'boat' is an anagram of 'abot'.
'abot' placed around 'b' is 'ABBOT'.
Can you help me to learn more?
(Other definitions for abbot that I've seen before include "Religious leader" , "Convent leader, male" , "Religious man" , "Superior monk" , "first in order" .)
