Piece of bric-a-brac will get us to be inquisitive (5)
I believe the answer is:
curio
'piece of bric-a-brac' is the definition.
'curio' can be an answer for 'bric-a-brac' (I've seen this in another clue). I am unsure of the 'piece of' bit.
I don't understand the remainder of the clue.
Can you help me to learn more?
(Other definitions for curio that I've seen before include "(Unusual) collector's item" , "Unusual, intriguing object" , "bit of bric-a- brac" , "Bygone" , "Object of interest because it is a rare or unusual" .)
