Far from concise record entered by knight (4)
I believe the answer is:
long
'far from concise' is the definition.
(concise means short or brief)
'record entered by knight' is the wordplay.
'record' becomes 'log' (log is a kind of record).
'entered by' means one lot of letters goes inside another (I've seen this in other clues).
'knight' becomes 'n' (chess).
'log' going around 'n' is 'LONG'.
(Other definitions for long that I've seen before include "dream" , "Sustained" , "hunger" , "Yearn (for)" , "to be tall" .)
