Sending the circuitry (6)
I believe the answer is:
wiring
This clue might be a double definition.
'sending' is the first definition.
The answer and definition can be both acts as well as being singular nouns.
Maybe you can see a link between them that I don't see?
'circuitry' is the second definition.
The definition and answer can be both man-made objects as well as being singular nouns.
Maybe you can see an association between them that I can't see?
'the' acts as a link.
Can you help me to learn more?
(Other definitions for wiring that I've seen before include "electrical work" , "working as electricians" , "Electrics" , "Building's electrical installation" , "work for electrician" .)
