Quiet beer knocked back entertaining one Australian woman (6)
I believe the answer is:
sheila
'australian woman' is the definition.
'Sheila' can be an answer for 'woman' (I've seen this before). I am not certain of the 'australian' bit.
'quiet beer knocked back entertaining one' is the wordplay.
'quiet' becomes 'sh'.
'beer' becomes 'ale' (I've seen this before).
'knocked back' is a reversal indicator.
'entertaining' is an insertion indicator.
'one' becomes 'i' (Roman numeral).
'ale' written backwards gives 'ela'.
'ela' going around 'i' is 'eila'.
'sh'+'eila'='SHEILA'
Can you help me to learn more?
(Other definitions for sheila that I've seen before include "bird?" , "Aussie lady?" , "Girl's name (any Oz girl?)" , "Woman (Aus. colloq.)" , "Female name" .)
