Meant not to be caught in act (7)
I believe the answer is:
denoted
'meant' is the definition.
(denoting is a kind of meaning)
'not to be caught in act' is the wordplay.
'to be caught in' means one lot of letters goes inside another.
'act' becomes 'deed' (deed is a kind of act).
'not' inserted into 'deed' is 'DENOTED'.
(Other definitions for denoted that I've seen before include "Indicated or meant" , "Signified" .)
