Put paid net inside (6)
I believe the answer is:
placed
'put' is the definition.
(I've seen this before)
'paid net inside' is the wordplay.
'paid' becomes 'pd' (I've seen this in other clues).
'net' becomes 'lace' (I can't justify this - if you can you should give a lot more credence to this answer).
'inside' means one lot of letters goes inside another.
'pd' going around 'lace' is 'PLACED'.
Can you help me to learn more?
(Other definitions for placed that I've seen before include "Put in position" , "In the first three" , "Set" , "Came second or third" , "Put, situated" .)
