Pronouncedly feeble for a time (4)
I believe the answer is:
week
'time' is the definition.
(period of time)
I don't understand the rest of the clue.
Can you help me to learn more?
(Other definitions for week that I've seen before include "Calendar period" , "Part of the year" , "Seven days" , "A long time in politics?" , "Seven day period" .)
