The good fellow will always share a half bottle with a seaman (5)
I believe the answer is:
abbot
'the good fellow will always share a' is the definition.
I can't judge whether this defines the answer.
'half bottle with a seaman' is the wordplay.
'half' suggests halving the letters.
'with' says to put letters next to each other.
'a seaman' becomes 'ab' (short for able seaman).
'bottle' with half the letters taken is 'bot'.
'bot' after 'ab' is 'ABBOT'.
Can you help me to learn more?
(Other definitions for abbot that I've seen before include "Head of religious house" , "Monks' superior" , "Monastic superior" , "meeting Newton in Devon" , "Religious leader" .)
