Nicely manoeuvres round measure for tolerance (8)
I believe the answer is:
leniency
'for tolerance' is the definition.
(leniency is a kind of tolerance)
'nicely manoeuvres round measure' is the wordplay.
'manoeuvres' is an anagram indicator (letters manoeuvred in a new way).
'round' indicates putting letters inside.
'measure' becomes 'en' (en is a unit of measurement used by printers).
'nicely' is an anagram of 'lenicy'.
'lenicy' placed around 'en' is 'LENIENCY'.
(Other definitions for leniency that I've seen before include "Clemency, mercy" , "Opposite of severity - state of mildness" , "Lenny, CIE shows mercy" , "Mildness and tolerance" , "Mercy, tolerance" .)
