Plagued β by a piece of it? (4)
I believe the answer is:
ague
'it?' is the definition.
I can't tell whether this defines the answer.
'plagued by a piece' is the wordplay.
'a piece' says the answer is hidden in the clue.
'AGUE' can be found hidden inside 'plagued by'.
'of' acts as a link.
Can you help me to learn more?
(Other definitions for ague that I've seen before include "Chills and fever" , "Fever (archaic)" , "Burning fever" , "nasty illness?" , "Illness with fever and shivering, malaria say" .)
