I am able to follow co-star from a Central American country (5,5)
I believe the answer is:
costa rican
'a central american country' is the definition.
Although both the answer and definition are singular nouns, I don't see how they can define each other.
'i am able to follow co-star' is the wordplay.
'i am able' becomes 'I can' (I can).
'to follow' says to put letters next to each other.
'co'+'star'='costar'
'ican' put after 'costar' is 'COSTA-RICAN'.
'from' acts as a link.
Can you help me to learn more?
(Other definitions for costa rican that I've seen before include "from Central America" , "Central American" , "maybe a Hispanic type" , "Latin American" , "Foreign" .)
