Come out of the ground in good condition (4)

I believe the answer is:

well

I'm a little stuck... Click here to teach me more about this clue!

'in good condition' is the definition.
(I've seen this before)

I can't explain the remainder of the clue.

(Other definitions for well that I've seen before include "Healthy - water supply" , "Very possibly" , "Healthy - source of water" , "Bore; very much" , "Fit and healthy" .)

I've seen this clue in the Sydney Morning Herald.
