Is leaving this beneath Queen’s old newspaper (9)
I believe the answer is:
thunderer
'old newspaper' is the definition.
Although both the answer and definition are singular nouns, I can't see how one could define the other.
'is leaving this beneath queen's' is the wordplay.
'leaving' indicates named letters should be taken away.
'beneath' becomes 'under' (I've seen this before).
'queen' becomes 'er' (abbreviation for Elizabeth Regina).
'this' with 'is' removed is 'th'.
'th'+'under'+'er'='THUNDERER'
Can you help me to learn more?
(Other definitions for thunderer that I've seen before include "Jupiter, say" , "Our paper" , "Loud protester" , "The -, nickname for The Times" .)
