Predominance needs control -- little good in it (5)
I believe the answer is:
reign
'predominance' is the definition.
(I've seen this before)
'control little good in it' is the wordplay.
'control' becomes 'rein' (rein is a kind of control**).
'little' indicates taking the first letters.
'in it' indicates putting letters inside.
The initial letter of 'good' is 'g'.
'rein' going around 'g' is 'REIGN'.
'needs' is the link.
(Other definitions for reign that I've seen before include "Dominion" , "Govern" , "Occupy the throne" , "Time on throne" , "are unbeatable!" .)
