What may be heard from pit crosses Olympic colosseum (7)
I believe the answer is:
piccolo
'what may be heard' is the definition.
I can't judge whether this definition defines the answer.
'pit crosses olympic colosseum' is the wordplay.
'PICCOLO' is hidden within the letters.
But, I am unsure how this is indicated.
'from' acts as a link.
Can you help me to learn more?
(Other definitions for piccolo that I've seen before include "Little flute" , "Part of 14 [ORCESTRA]" , "High wind instrument" , "producer of note" , "Smallest of the flute family" .)
