Big hole in baby's shawl (5)
I believe the answer is:
abyss
'big hole' is the definition.
(an abyss is a large chasm or pit)
I can't explain the rest of the clue.
Can you help me to learn more?
(Other definitions for abyss that I've seen before include "Very large and deep chasm" , "Fathomless pit" , "Bottomless pit" , "Deep gulf" , "Hell; hole" .)
