The capital gets poor return in this company (5)
I believe the answer is:
troop
'this company' is the definition.
(I've seen this before)
'the capital gets poor return' is the wordplay.
'capital' indicates taking the first letters.
'gets' means one lot of letters go next to another.
'return' says the letters should be written in reverse.
The initial letter of 'the' is 't'.
'poor' backwards is 'roop'.
't'+'roop'='TROOP'
'in' is the link.
(Other definitions for troop that I've seen before include "Gang" , "platoon?" , "Group of people or animals" , "A company, unit" , "Body of soldiers or scouts" .)
