Model of Greek sea god only half complete (4)
I believe the answer is:
yoke
'model' is the definition.
The answer and definition can be both man-made objects as well as being singular nouns.
Perhaps you can see an association between them that I can't see?
'greek sea god only half complete' is the wordplay.
'greek sea' becomes 'yok' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'god' becomes 'Re' (Re is an example).
'only half complete' suggests halving the letters.
're' cut in half is 'e'.
'yok'+'e'='YOKE'
'of' acts as a link.
Can you help me to learn more?
(Other definitions for yoke that I've seen before include "An oppressive and burdensome restraint" , "Oxen harness" , "Badge of slavery" , "Coupling" , "Eg, pair of draught oxen" .)
