Install incomer's IT equipment (8)
I believe the answer is:
computer
'equipment' is the definition.
The definition and answer can be both man-made objects as well as being singular nouns.
Maybe you can see a link between them that I can't see?
'install incomer's it' is the wordplay.
I cannot quite understand how this works, but
'install' could be 'put' (I've seen this in another clue) and 'put' is located in the answer.
'it' could be 'e' ('e' can mean 'electronic' which is similar to 'IT') and 'e' is found within the answer.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for computer that I've seen before include "Programmable machine" , "Laptop, perhaps" , "Electronic calculator" , "Comer put out by data processing machine" , "Curt poem (anag)" .)
