Extremely, exceedingly (4,2)
I believe this is a double definition.
'extremely' is the first definition.
(I've seen this in another clue)
'exceedingly' is the second definition.
(I've seen this in another clue)
(Other definitions for ever so that I've seen before include "Intensifier" , "To a very great extent" , "really" , "Greatly" , "Very much" .)
