Average beer refreshed hard worker (5,6)
I believe the answer is:
eager beaver
'hard worker' is the definition.
'eager beaver' can be an answer for 'worker' (eager beaver is a kind of worker). I am unsure of the 'hard' bit.
'average beer refreshed' is the wordplay.
'refreshed' indicates anagramming the letters.
'average'+'beer'='averagebeer'
'averagebeer' is an anagram of 'EAGER BEAVER'.
Can you help me to learn more?
(Other definitions for eager beaver that I've seen before include "Very keen individual" , "Alert and energetic person" , "Someone who's (too) enthusiastic about work" , "Diligent worker" , "Enthusiast - zealous person - one too eager to work" .)
