Greek character back in bed – just like a man (5)
I believe the answer is:
biped
'a man' is the definition.
(humans are an example)
'greek character back in bed' is the wordplay.
'greek character' becomes 'pi' (letter from the Greek alphabet).
'back' says the letters should be written backwards.
'in' indicates putting letters inside.
'pi' written backwards gives 'ip'.
'ip' placed into 'bed' is 'BIPED'.
'just like' acts as a link.
I am not very happy about this link. Some or all of it may belong to another bit of the clue.
Can you help me to learn more?
(Other definitions for biped that I've seen before include "One standing on two feet" , "Two-footed creature" , "Man, perhaps" , "Two-legged animal" , "One walking on two legs" .)
