Think of America (5)
I believe the answer is:
guess
This clue might be a double definition.
'think' is the first definition.
(synonyms)
'america' is the second definition.
Although both the answer and definition are singular nouns, I can't understand how one could define the other.
'of' acts as a link.
Can you help me to learn more?
(Other definitions for guess that I've seen before include "Speculate" , "Estimate, supposition" , "Hypothesis" , "Estimate; suppose" , "Theory" .)
