Looks at the said agreements (4)
I believe the answer is:
eyes
'looks at' is the definition.
(I've seen this before)
I cannot understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for eyes that I've seen before include "Ogles" , "Looks at - organs" , "They have pupils" , "Storm centres" , "Optical organs" .)
