Balcony initially terrified the Queen and family (7)
I believe the answer is:
terrace
'balcony' is the definition.
(I've seen this before)
'initially terrified the queen and family' is the wordplay.
'initially' suggests taking the first letters.
'the queen' becomes 'ER' (Elizabeth Regina).
'and' is a charade indicator (letters next to each other).
'family' becomes 'race' (I can't explain this - if you can you should believe this answer much more).
The first letter of 'terrified' is 't'.
't'+'er'+'race'='TERRACE'
Can you help me to learn more?
(Other definitions for terrace that I've seen before include "street" , "Urban housing" , "Hillside level" , "Caterer (anag) - houses in a row" , "Balcony" .)
