Old lady alarmed about food delivered to Paddington? (9)
I believe the answer is:
marmalade
'food delivered to paddington?' is the definition.
I can't tell whether this definition defines the answer.
'old lady alarmed about' is the wordplay.
'old lady' becomes 'ma' (both can informally mean mother).
'about' indicates an anagram.
'alarmed' with letters rearranged gives 'rmalade'.
'ma'+'rmalade'='MARMALADE'
Can you help me to learn more?
(Other definitions for marmalade that I've seen before include "Spread" , "Preserve made with citrus fruits" , "Sweet food" , "Orange conserve" , "Eleven's [PRESERVE]" .)
