Sports car in a large Somerset town keeping acceleration at zero (4,5)
I believe the answer is:
alfa romeo
'sports car' is the definition.
(I've seen this before)
'a large somerset town keeping acceleration at zero' is the wordplay.
'large' becomes 'L' (eg in clothes sizes).
'somerset town' becomes 'frome' (I've seen this before).
'keeping' indicates putting letters inside (some letters kept inside).
'acceleration' becomes 'a' (symbol used in Physics e.g. f=ma).
'at zero' becomes 'o' (I can't explain this - if you can you should believe this answer much more).
'frome' placed around 'a' is 'farome'.
'a'+'l'+'farome'+'o'='ALFA ROMEO'
'in' acts as a link.
Can you help me to learn more?
(Other definitions for alfa romeo that I've seen before include "sports car" , "Italian car" .)
