Manacle with copper in bad mood (8)
I believe the answer is:
handcuff
'manacle' is the definition.
(I know that manacle can be written as handcuff)
'with copper in bad mood' is the wordplay.
'with' becomes 'and'.
'copper' becomes 'c' (this could be a standard abbreviation which I don't know about).
'in' indicates putting letters inside.
'bad mood' becomes 'huff' (someone 'in a huff' is in a bad mood).
'and'+'c'='andc'
'andc' placed into 'huff' is 'HANDCUFF'.
Can you help me to learn more?
(Other definitions for handcuff that I've seen before include "Shackle by the wrist" , "Restraint" , "Put bracelets on" , "Restrict movement" , "Manacle" .)
