See and set free what got caught in it (5)
I believe the answer is:
watch
'see' is the definition.
(I know that see is a more specific form of the action the watch)
'set free what got caught in it' is the wordplay.
'set free' is an anagram indicator (the letters are free to move around).
'got caught' becomes 'c' (I can't justify this - if you can you should believe this answer much more).
'in it' is an insertion indicator.
'what' anagrammed gives 'wath'.
'wath' going around 'c' is 'WATCH'.
'and' is the link.
Can you help me to learn more?
(Other definitions for watch that I've seen before include "period of duty" , "Look at attentively" , "View" , "Keep an eye on - timepiece" , "Vigil" .)
