Report of outstanding au pair (3)
I believe the answer is:
duo
This clue could be a double definition.
'report of outstanding au' is the first definition.
The definition and answer can be both quantities as well as being singular nouns.
Maybe they are linked in a way I don't understand?
'pair' is the second definition.
(two people)
Can you help me to learn more?
(Other definitions for duo that I've seen before include "Pair of performers" , "Pair of singers" , "A team of two" , "Musical pair" , "Couple, pair" .)
