Weaknesses resume basically, impeding individual returns (7)
I believe the answer is:
foibles
'weaknesses' is the definition.
(I've seen this before)
I cannot understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for foibles that I've seen before include "Quirks" , "Fob lies about harmless peculiarities" , "Minor character faults" , "Weaknesses" .)
