Like final person appearing, having left a big game (6)
I believe the answer is:
latest
'like final person appearing' is the definition.
Both the definition and answer are adjectives. Perhaps they are linked in a way I don't understand?
'left a big game' is the wordplay.
'left' becomes 'l' (common abbreviation).
'big game' becomes 'test' (I've seen this before).
'l'+'a'+'test'='LATEST'
'having' acts as a link.
Can you help me to learn more?
(Other definitions for latest that I've seen before include "Of most recent date" , "Most recent or tardiest" , "Most up to the minute" , "coming after all the others" , "Brand new, just out" .)
