Wally taking spool from loom, then second spool (5)
I believe the answer is:
twerp
'second spool' is the definition.
The answer and definition can be both people as well as being singular nouns.
Perhaps they are linked in a way I don't understand?
I cannot understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for twerp that I've seen before include "dope" , "Foolish fellow" , "Pillock" , "Idiot" , "Contemptible type" .)
