Prophet's little house by the sea (5)
I believe the answer is:
hosea
'prophet's' is the definition.
(Old Testament figure)
'little house by the sea' is the wordplay.
'little house' becomes 'ho' (abbreviation for house. I am not sure about the 'little' bit.).
'by' means one lot of letters go next to another.
'ho'+'sea'='HOSEA'
Can you help me to learn more?
(Other definitions for hosea that I've seen before include "Hebrew prophet; book of Bible" , "Good book" , "OT prophet" , "Book of prophecies" , "OT prophet/book" .)
