Makes prisoners trust Clarke's first reforms (10)

I believe the answer is:

constructs

'makes' is the definition.
('construct' can be a synonym of 'make')

'prisoners trust clarke's first reforms' is the wordplay.
'prisoners' becomes 'cons'.
'first' says to take the initial letters.
'reforms' is an anagram indicator.
The first letter of 'clarke' is 'c'.
'trust'+'c'='trustc'
'trustc' with letters rearranged gives 'tructs'.
'cons'+'tructs'='CONSTRUCTS'

(Another definition for constructs that I've seen is " Makes".)

I've seen this clue in The Telegraph.
