Aged fool dares to have it (3)
I believe the answer is:
old
'it' is the definition.
The definition suggests a singular noun which matches the answer.
'aged fool dares to have' is the wordplay.
'to have' indicates a hidden word.
'OLD' can be found hidden inside 'aged fool dares'.
Can you help me to learn more?
(Other definitions for old that I've seen before include "Stale" , "out of the ark" , "Long in the tooth" , "Vintage" , "At an early stage - at a late stage" .)
