Fun fact! Leaders of the Republicans in Virginia invented aerobics (6)
I believe the answer is:
trivia
'fun fact' is the definition.
Although both the answer and definition are singular nouns, I can't understand how one could define the other.
'leaders of the republicans in virginia invented aerobics' is the wordplay.
'leaders of' indicates taking the first letters.
The first letters of 'the republicans in virginia invented aerobics' is 'TRIVIA'.
Can you help me to learn more?
