Caucasian continent? (4)
I believe the answer is:
'continent?' is the definition.
(Asia is an example)
'caucasian' is the wordplay.
'ASIA' is hidden within the letters.
However, I am unsure how the hidden word is indicated.
Can you help me to learn more?
(Other definitions for asia that I've seen before include "Large area", "Continent bordering three oceans", "Thailand and its location", "Earth's largest continent", "A vast number of people have lived here".)
