"Well, gosh!" (3)
I believe the answer is:
gee
I believe this clue is a double definition.
'well' is the first definition.
(I know that well can be written as gee)
'gosh' is the second definition.
(I know that gosh can be written as gee)
(Other definitions for gee that I've seen before include "crumbs" , "provided by substitute for ginger?" , "Mild exclamation" , "American exclamation" , "Gracious" .)
