Good, clear framework (4)
I believe the answer is:
grid
'framework' is the definition.
(I've seen this in another clue)
'good clear' is the wordplay.
'good' becomes 'g' (abbreviation).
'clear' becomes 'rid' (synonyms).
'g'+'rid'='GRID'
(Other definitions for grid that I've seen before include "What's above these clues" , "F1 starting point" , "Network of horizontal andvertical lines" , "Bars used to make one" , "Regular pattern of horizontal and vertical lines" .)
