Can you help me to learn more?
(Other definitions for grenada that I've seen before include "West Indian country" , "Island just north of Trinidad" , "West Indian island" , "Nation" , "commonwealth state" .)
But I've got no explanation for this one! Could you help me understand?
(Other definitions for estonia that I've seen before include "On a site (anag)" , "Baltic republic, capital Tallinn" , "European country, capital Tallinn" , "Republic in northeastern Europe" , "'So eat in here in Tallinn, say (7)'" .)
