Woolly lot of wild geese (5)
I believe the answer is:
skein
This might be a double definition.
'woolly lot' is the first definition.
The definition and answer can be both man-made objects as well as being singular nouns.
Perhaps you can see a link between them that I can't see?
'wild geese' is the second definition.
Both the definition and answer are singular nouns.
Perhaps you can see an association between them that I don't see?
'of' is the link.
Can you help me to learn more?
(Other definitions for skein that I've seen before include "Loosely coiled bundle of wool" , "Hank" , "Coil of wool - flock of geese" , "Loosely coiled length of thread" , "Loose coil of yarn" .)
