Look at some of the yearly reports (3)
I believe the answer is:
eye
'look at' is the definition.
(I've seen this before)
'some of the yearly reports' is the wordplay.
'some of' indicates a hidden word.
'EYE' can be found hidden inside 'the yearly reports'.
(Other definitions for eye that I've seen before include "Perception" , "Symmetrical spot" , "Viewer" , "Optic organ" , "Middle of storm" .)
