Common? Hardly! (6)
I believe the answer is:
scarce
This could be a double definition.
'common?' is the first definition.
Both the answer and definition are adjectives. Maybe they are linked in a way I don't understand?
'hardly' is the second definition.
(I know that hardly can be written as scarce)
Can you help me to learn more?
(Other definitions for scarce that I've seen before include "Not enough to satisfy demand" , "Insufficient to meet demand" , "Rarely found" , "Few and far between" , "Not plentiful, in short supply" .)
