Bony eel takes cooking (8)
I believe the answer is:
skeletal
'bony' is the definition.
(synonyms)
'eel takes cooking' is the wordplay.
I cannot quite see how this works, but
an anagram of 'eel' is 'ele' which is within the answer.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for skeletal that I've seen before include "Pulchritude" , "Bony, gaunt" , "Comprising just the bare bones" , "Like a framework of lakelets" , "Dreadfully thin" .)
