Short notice, fair and correct (6)
I believe the answer is:
adjust
'correct' is the definition.
(adjusting is a kind of correcting)
'short notice fair and' is the wordplay.
'short' means to remove the last letter.
'notice' becomes 'ad'.
'fair' becomes 'just' ('just' can be a synonym of 'fair').
'and' becomes 'n' (common abbreviation for 'and').
'ad'+'just'+'n'='adjustn'
'adjustn' with its final letter taken away is 'ADJUST'.
(Other definitions for adjust that I've seen before include "Adapt, regulate" , "Modify - tweak" , "Arrange, put into proper position" , "Make small changes" , "Make slight corrections to" .)
