Two men are foreign (7)
I believe the answer is:
russian
'foreign' is the definition.
Although both the answer and definition are adjectives, I cannot understand how they can define each other.
'two men' is the wordplay.
'two men' can mean two substitutions for 'man'.
'man' becomes 'russ' ().
'man' becomes 'ian' (man's name).
'russ'+'ian'='RUSSIAN'
'are' acts as a link.
Can you help me to learn more?
(Other definitions for russian that I've seen before include "Native of the world's largest country" , "Muscovite possibly" , "Eg, Moscow native" , "Slavonic tongue" , "Slav" .)
