Spring better (4)
I believe the answer is:
well
I believe this is a double definition.
'spring' is the first definition.
(I've seen this before)
'better' is the second definition.
(similar in meaning)
(Other definitions for well that I've seen before include "Facial hair" , "Healthy - water supply" , "Spring - in good health" , "water is found here" , "Very; deep shaft" .)
