Run out returned soldier and remove ship's accoutrements (5)
I believe the answer is:
unrig
'and remove ship's accoutrements' is the definition.
I can't tell whether this defines the answer.
'run out returned soldier' is the wordplay.
'out' indicates an anagram (out can mean wrong or inaccurate).
'returned' is a reversal indicator.
'soldier' becomes 'GI' (GI can mean a US soldier).
'gi' reversed gives 'ig'.
'run' is an anagram of 'unr'.
'unr'+'ig'='UNRIG'
Can you help me to learn more?
(Other definitions for unrig that I've seen before include "(Of a boat) strip of its mast, stays etc" , "Take down sails" , "Dismantle" , "Take tackle out" , "In rug (anag.)" .)
