Ethnic grouping comprising half of Greece's constituents? (9)
I believe the answer is:
europeans
'constituents?' is the definition.
The definition and answer can be both people as well as being plural nouns.
Perhaps they are linked in a way I don't understand?
I can't explain the remainder of the clue.
Can you help me to learn more?
(Other definitions for europeans that I've seen before include "The French and Italians, say" , "Irish and French people, say" , "Frenchmen, Irishwomen, for instance" , "Continentals" .)
