From US area, I travelled to another land mass (7)
I believe the answer is:
eurasia
'land mass' is the definition.
(I've seen this before)
'from us area i' is the wordplay.
'from' indicates an anagram (from the letters).
'us'+'area'+'i'='usareai'
'usareai' is an anagram of 'EURASIA'.
'travelled to another' is the link.
This may not be right. Some or all of it may be part of another bit of the clue.
Can you help me to learn more?
(Other definitions for eurasia that I've seen before include "Largest landmass" , "Land mass - use aria (anag)" , "Large northern hemisphere land mass" , "Germany and Japan are in it" , "Two continents, considered as a whole" .)
