Hide in study, getting secure, we hear (7)
I believe the answer is:
conceal
'hide' is the definition.
(I know that hide can be written as conceal)
'study getting secure we hear' is the wordplay.
I cannot really understand how this works, but
'study' could be 'con' (con can mean to study) and 'con' is found in the answer.
This explanation may well be incorrect...
'in' is the link.
Can you help me to learn more?
(Other definitions for conceal that I've seen before include "Screen" , "Keep out of sight" , "'Hide, keep secret (7)'" , "hush up!" , "Place out of sight" .)
