Catch and stuff (3)

I believe the answer is:

net

I'm a little stuck... Click here to teach me more about this clue!

'catch' is the definition.
(net can mean to catch)

'and stuff' is the wordplay.
'and' becomes 'n' (common abbreviation for 'and').
'stuff' becomes 'et' (I can't justify this - if you can you should believe this answer much more).
'n'+'et'='NET'

Can you help me to learn more?

(Other definitions for net that I've seen before include "What separates court opponents" , "After taxes" , "Tennis court feature" , "catch fish" , "Ultimate" .)

I've seen this clue in the Evening Standard.
