Press to cease production at the end of it (6)
I believe the answer is:
closet
'press' is the definition.
('closet' can be a synonym of 'press')
'cease production at the end of it' is the wordplay.
'cease' becomes 'cl' (I can't explain this - if you can you should give a lot more credence to this answer).
'production' becomes 'os' (OS is an example).
'at' means one lot of letters go next to another.
'end of' indicates one should take the final letters.
'it' becomes 't' (abbreviation. e.g. in 'tis).
The last letter of 'the' is 'e'.
'cl'+'os'+'e'+'t'='CLOSET'
'to' acts as a link.
Can you help me to learn more?
(Other definitions for closet that I've seen before include "Study" , "secret is revealed" , "Covert" , "A small room - secret?" , "American cupboard or wardrobe" .)
