Managed to break two keys in piano (5)
I believe the answer is:
grand
'piano' is the definition.
(grand piano is a kind of piano)
'managed to break two keys' is the wordplay.
'managed' becomes 'ran' (I've seen this before).
'to break' means one lot of letters goes inside another.
'two keys' becomes 'gd' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'ran' inserted into 'gd' is 'GRAND'.
'in' is the link.
Can you help me to learn more?
(Other definitions for grand that I've seen before include "1,000 GBP" , "Marvellous" , "Majestic" , "GBP1,000" , "One thousand pounds" .)
