Wholehearted bore needing an audience (5)
I believe the answer is:
eager
I believe this is a triple definition!
'wholehearted' is the first definition.
(both can mean enthusiastic)
'bore' is the second definition.
(eager is a kind of bore)
'needing an audience' is the third definition.
'eager' can be an answer for 'needing' (thesaurus). I am not sure about the 'an audience' bit.
Can you help me to learn more?
(Other definitions for eager that I've seen before include "Showing keen interest" , "Impatient" , "Ardent" , "It's a bore" , "Enthusiastic, raring to go" .)
