Where it's never desperately short of royals, to start with? (7)
I believe the answer is:
windsor
'where it's never desperately short of royals to start with?' is the definition.
Although both the answer and definition are singular nouns, I cannot see how one could define the other.
'where it's never desperately short of royals to start with?' is the wordplay.
'to start with?' indicates taking the first letters (I've seen 'start with' mean this).
The initial letters of 'where its never desperately short of royals' is 'WINDSOR'.
Can you help me to learn more?
(Other definitions for windsor that I've seen before include "Royal house (or castle)" , "Royal castle; a tie knot" , "Weekend residence of the British royal family" , "9 [HOUSE]" , "British royal house" .)
