Mocked science on oxygen paper given by media boss (7)
I believe the answer is:
scoffed
'mocked' is the definition.
(I've seen this before)
'science on oxygen paper given by media boss' is the wordplay.
'science' becomes 'sc'.
'on oxygen paper' becomes 'off' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'given by' says to put letters next to each other.
'media boss' becomes 'ed' (short for editor).
'sc'+'off'+'ed'='SCOFFED'
Can you help me to learn more?
(Other definitions for scoffed that I've seen before include "Laughed at with contempt and derision" , "Showed no respect - ate greedily" , "Mocked" , "Jeered; ate" , "Expressed scorn" .)
