Continental in the biggest possible way (5)
I believe the answer is:
asian
'continental' is the definition.
(I've seen this before)
'biggest possible way' is the wordplay.
'biggest possible' becomes 'asia' (I can't explain this - if you can you should believe this answer much more).
'way' becomes 'n' (Compass direction - North).
'asia'+'n'='ASIAN'
'in the' acts as a link.
Can you help me to learn more?
(Other definitions for asian that I've seen before include "Relating to one continent" , "Eastern national" , "of Indian descent, say?" , "eg Pakistani" , "Easterner" .)
