A miner ordered to stay (6)
I believe the answer is:
remain
'stay' is the definition.
(synonyms)
'a miner ordered' is the wordplay.
'ordered' indicates an anagram.
'a'+'miner'='aminer'
'aminer' with letters rearranged gives 'REMAIN'.
'to' acts as a link.
(Other definitions for remain that I've seen before include "Stay, don't go" , "Survive" , "Stay behind" , "Last" , "Stay on after others have gone" .)
