Measure of wire, almost 1,760 yards (3)
I believe the answer is:
mil
'measure of wire' is the definition.
'mil' can be an answer for 'measure' (mil is a kind of measure). I am not certain of the 'of wire' bit.
'almost 1760 yards' is the wordplay.
'almost' means to remove the last letter (most of the word but not all of it).
'1760 yards' becomes 'mile' (I've seen this before).
'mile' with its final letter taken off is 'MIL'.
Can you help me to learn more?
(Other definitions for mil that I've seen before include "One thousandth of an inch" , "One thousanth of an inch" , "One / one thousand inch" , "tiny distance" .)
