Writer's little bed in outer space (6)
I believe the answer is:
scribe
'writer's' is the definition.
(scribe is a kind of writer)
'little bed in outer space' is the wordplay.
'little bed' becomes 'crib' (I've seen this before. I am not sure about the 'little' bit.).
'in' means one lot of letters goes inside another.
'outer' suggests removing the centre.
'space' with its middle taken out is 'se'.
'crib' put into 'se' is 'SCRIBE'.
Can you help me to learn more?
(Other definitions for scribe that I've seen before include "7 down teacher of the Jewish Law" , "One writing documents" , "Official writer" , "Scholar of Jewish law" , "Write" .)
