Look over moves to suppress mad cow disease (7)
I believe the answer is:
observe
'look' is the definition.
(I've seen this before)
'over moves to suppress mad cow disease' is the wordplay.
'moves' is an anagram indicator.
'to suppress' means one lot of letters goes inside another.
'mad cow disease' becomes 'bse' (bovine spongiform encephalopathy).
'over' with letters rearranged gives 'orve'.
'orve' placed around 'bse' is 'OBSERVE'.
(Other definitions for observe that I've seen before include "Keep an eye on" , "What this newspaper does?" , "obey" , "Watch attentively" , "Keep; notice" .)
