Out of the country, on plane republican moves two places ahead (6)
I believe the answer is:
abroad
'out of the country' is the definition.
(I've seen this before)
I cannot understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for abroad that I've seen before include "Away in another country" , "on the Continent" , "over a wide area" , "At large - overseas" , "Pole would be so" .)
