Arias about Brussels starting to get a lot of land (7)
I believe the answer is:
eurasia
'land' is the definition.
(Eurasia is an example)
'arias about brussels starting to get a lot' is the wordplay.
I cannot quite understand how this works, but
an anagram of 'arias' is 'rasia' which is located in the answer.
'brussels' could be 'eu' (European Parliament is based in Brussels) and 'eu' is found within the answer.
No letters remain.
This may be the basis of the clue (or it may be nonsense).
'of' is the link.
Can you help me to learn more?
(Other definitions for eurasia that I've seen before include "Large landmass combining two continents" , "Unbroken landmass bearing two continents" , "Landmass extending from Cape Roca in the west to Cape Dezhnev in the east" , "Large northern hemisphere land mass" , "Continental land mass" .)
