General way to expand (7)
I believe the answer is:
enlarge
'to expand' is the definition.
(I've seen this in another clue)
'general way' is the wordplay.
'way' indicates anagramming the letters (another way of arranging the letters).
'general' with letters rearranged gives 'ENLARGE'.
(Other definitions for enlarge that I've seen before include "Stretch" , "Broaden, increase" , "Make big" , "Amplify" , "Gleaner (anag.)" .)
