In a glass case at the chateau? (7)
I believe the answer is:
bottled
'in' is the definition.
The answer and definition are not the same part of speech. However, past participle verbs and adjectives occasionally mean the same thing.
I don't understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for bottled that I've seen before include "Stored in glass" , "Preserved in jars" , "confined by Nebuchadnezzar?" , "Attacked in pub" .)
