Idiot to help with bird stuffing (7)
I believe the answer is:
airhead
'idiot' is the definition.
(I've seen this before)
'help with bird stuffing' is the wordplay.
'help' becomes 'aid' (synonyms).
'with' means one lot of letters goes inside another.
'bird stuffing' becomes 'rhea' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'aid' placed around 'rhea' is 'AIRHEAD'.
'to' acts as a link.
Can you help me to learn more?
(Other definitions for airhead that I've seen before include "One not very bright" , "One's simple" , "military base behind enemy lines" , "one with a small brain" , "Bimbo" .)
