Overstated the number (3)
I believe the answer is:
two
This might be a double definition.
'overstated' is the first definition.
Both the definition and answer are adjectives. Maybe you can see a link between them that I don't see?
'the number' is the second definition.
(two is a kind of number)
Can you help me to learn more?
(Other definitions for two that I've seen before include "Even number" , "One plus one" , "Fifth root of thirty-two" , "limited company?" , "Between one and three" .)
