He ran to different unnamed player (7)
I believe the answer is:
another
'unnamed player' is the definition.
Although both the answer and 'player' are adjectives, they are not in the same form of the adjective.
'he ran to different' is the wordplay.
'different' is an anagram indicator (letters placed in a different order).
'he'+'ran'+'to'='heranto'
'heranto' anagrammed gives 'ANOTHER'.
Can you help me to learn more?
(Other definitions for another that I've seen before include "Somebody else" , "Additional: alternative" , "Player or person not yet named or selected" , "Someone else" , "A different one" .)
