Last time said you are on the largest continent and the largest continental area (7)
I believe the answer is:
eurasia
'the largest continental area' is the definition.
'eurasia' can be an answer for 'area' (I have seen 'Huge area' mean 'eurasia' so perhaps 'area' could also mean 'eurasia'). I'm not sure about the 'the largest continental' bit.
'last time said you are on the largest continent' is the wordplay.
'last time' becomes 'r' (I can't justify this - if you can you should believe this answer much more).
'said' shows a homophone (sound like).
'are on' means one lot of letters go next to another.
'the largest continent' becomes 'asia' (I've seen this in another clue).
'you' is a homophone of 'eu'.
'r' after 'eu' is 'eur'.
'eur'+'asia'='EURASIA'
'and' is the link.
Can you help me to learn more?
(Other definitions for eurasia that I've seen before include "Turkey, and so on" , "Large northern hemisphere land mass" , "Land mass - use aria (anag)" , "Two continents considered as one" , "Germany and Japan are in it" .)
