Put off by pressure working in new depots (9)
I believe the answer is:
postponed
'put off' is the definition.
(I've seen this before)
'pressure working in new depots' is the wordplay.
'pressure' becomes 'p' (scientific abbreviation).
'working' becomes 'on' (on can mean working or activated).
'in' means one lot of letters goes inside another.
'new' indicates an anagram.
'depots' anagrammed gives 'ostped'.
'on' going inside 'ostped' is 'ostponed'.
'p'+'ostponed'='POSTPONED'
'by' is the link.
(Other definitions for postponed that I've seen before include "Deferred" , "delayed" , "Put off" .)
