These egg boxes detect surroundings (3)
I believe the answer is:
see
'detect surroundings' is the definition.
'see' can be an answer for 'detect' (I've seen this in another clue). I am not sure about the 'surroundings' bit.
'these egg boxes' is the wordplay.
'boxes' indicates the answer is hidden within the clue (to box can mean to contain).
'SEE' can be found hidden inside 'these egg'.
Can you help me to learn more?
(Other definitions for see that I've seen before include "Observe the bishop's jurisdiction" , "Visualise" , "Go out with; notice" , "Observe the papacy in Rome" , "Bishop's area of control" .)
