Investment finally gets a poor return for this group (5)
I believe the answer is:
troop
'this group' is the definition.
The answer and definition can be both groups as well as being singular nouns.
Maybe there's an association between them I don't understand?
'investment finally gets a poor return' is the wordplay.
'finally' suggests the final letters.
'gets' means one lot of letters go next to another.
'return' is a reversal indicator.
The last letter of 'investment' is 't'.
'poor' in reverse letter order is 'roop'.
't'+'roop'='TROOP'
'for' is the link.
Can you help me to learn more?
(Other definitions for troop that I've seen before include "Band of people" , "Body of soldiers or scouts" , "Group of kangaroos" , "Cavalry unit commanded by a captain" , "Proto (anag.)" .)
