Enough said, every now and then, on match (8)
I believe the answer is:
adequate
'enough' is the definition.
(I know that enough can be written as adequate)
'said every now and then on match' is the wordplay.
'every now and then' indicates alternate letters (letters selected at regular intervals).
'on' says to put letters next to each other.
'match' becomes 'equate' (to equate is to match or be equivalent).
The alternating letters of 'said' are 'ad'.
'ad'+'equate'='ADEQUATE'
(Other definitions for adequate that I've seen before include "Enough to meet a purpose" , "Just about sufficient, acceptable" , "Passable; enough" , "Barely sufficient" , "Satisfactory, good enough" .)
