Stock exchange member concerned with missile turning up (6)
I believe the answer is:
trader
'stock exchange member' is the definition.
The definition and answer can be both people as well as being singular nouns.
Maybe they are linked in a way I don't understand?
'concerned with missile turning up' is the wordplay.
'concerned with' becomes 're'.
'missile' becomes 'dart' (dart is a kind of missile).
'turning up' is a reversal indicator.
're'+'dart'='redart'
'redart' reversed gives 'TRADER'.
Can you help me to learn more?
(Other definitions for trader that I've seen before include "Merchant ship; dealer" , "He buys and sells goods" , "Dealer who buys and sells" , "Red tar (anag)" , "One selling" .)
