Wealthy; fertile (4)
I believe the answer is:
rich
I believe this is a double definition.
'wealthy' is the first definition.
(similar in meaning)
'fertile' is the second definition.
(I know that fertile can be written as rich)
(Other definitions for rich that I've seen before include "Lord Chancellor" , "Well-heeled" , "very funny?" , "Full-bodied" , "productive" .)
