Quiet orphan girl runs carrying basket (7)
I believe the answer is:
pannier
'carrying basket' is the definition.
(I've seen this before)
'quiet orphan girl runs' is the wordplay.
'quiet' becomes 'p' (music symbol for 'piano', ie soft or quiet).
'orphan girl' becomes 'annie' (from the musical Annie).
'runs' becomes 'r' (cricket abbreviation).
'p'+'annie'+'r'='PANNIER'
(Other definitions for pannier that I've seen before include "Basket on, eg, donkey" , "Basket carried by animal" , "Bag carried on side of horse, bicycle etc" , "Large basket" , "Carrying basket" .)
