The number of dials in London (5)
I believe the answer is:
seven
This clue might be a double definition.
'the number' is the first definition.
(seven is a kind of whole number)
'dials in london' is the second definition.
Although both the answer and definition are singular nouns, I don't understand how one could define the other.
'of' is the link.
Can you help me to learn more?
(Other definitions for seven that I've seen before include "number of swans aswimming" , "Cardinal" , "Number (of stars in the sky?)" , "See 1" , "Prime number" .)
