Very cross with broken meter in city (9)
I believe the answer is:
extremely
'very' is the definition.
(I've seen this in another clue)
'cross with broken meter in city' is the wordplay.
'cross with' becomes 'x' (an X is a cross. I am not sure about the 'with' bit.).
'broken' indicates anagramming the letters.
'in' is an insertion indicator.
'city' becomes 'ely' (Ely is a city in Cambridgeshire).
'meter' anagrammed gives 'etrem'.
'x' placed within 'etrem' is 'extrem'.
'extrem'+'ely'='EXTREMELY'
Can you help me to learn more?
(Other definitions for extremely that I've seen before include "remarkably" , "To a high degree or extent" .)
