With which the thief broke the jeweller's window to get it? (5)
I believe the answer is:
stone
'with which the thief broke' is the definition.
I can't judge whether this defines the answer.
'jeweller's window to get it?' is the wordplay.
'jeweller's window' becomes 'sone' (I can't justify this - if you can you should believe this answer much more).
'to get' means one lot of letters goes inside another.
'sone' placed around 't' is 'STONE'.
'the' acts as a link.
Can you help me to learn more?
(Other definitions for stone that I've seen before include "Rag" , "Rock; hard seed" , "Gem; Staffs. town" , "Rock; gem" , "Hard lump of mineral matter" .)
