Nothing in degree for decoration (3)
I believe the answer is:
boa
'decoration' is the definition.
The answer and definition can be both man-made objects as well as being singular nouns.
Maybe there's a link between them I don't understand?
'nothing in degree' is the wordplay.
'nothing' becomes 'O' (O resembles 0).
'in' is an insertion indicator.
'degree' becomes 'ba' (Bachelor of Arts).
'o' going within 'ba' is 'BOA'.
'for' acts as a link.
Can you help me to learn more?
(Other definitions for boa that I've seen before include "Snake; feather stole" , "strangler" , "Snake; fur" , "... cold-blooded creature" , "Large S American snake" .)
