Possibly wake in an enfeebled condition (4)
I believe the answer is:
weak
'enfeebled condition' is the definition.
'weak' can be an answer for 'enfeebled' (thesaurus). I'm not sure about the 'condition' bit.
'possibly wake in' is the wordplay.
'wake' anagrams to 'WEAK'.
However, I'm not sure how this is indicated.
'an' acts as a link.
Can you help me to learn more?
(Other definitions for weak that I've seen before include "Faint; frail" , "Puny" , "Easily led" , "Feeble or frail" , "Spent" .)
