Prepare endlessly and study in China (7)
I believe the answer is:
dresden
'china' is the definition.
(a type of porcelain)
'prepare endlessly and study in' is the wordplay.
'prepare' becomes 'dress' (dressing is a kind of preparing).
'endlessly' means to remove the last letter.
'and' is a charade indicator (letters next to each other).
'study in' becomes 'den' (term for a study or office. I am not sure about the 'in' bit.).
'dress' with its final letter taken off is 'dres'.
'dres'+'den'='DRESDEN'
Can you help me to learn more?
(Other definitions for dresden that I've seen before include "Fine china named after German city" , "Decorated china" , "Famous china made at Meissen" , "German city known for its china" , "Red Ned's in the German city" .)
