They help you see the detailed requirements (5)
I believe the answer is:
specs
This clue might be a double definition.
'they help' is the first definition.
Although both the answer and definition are singular nouns, I can't understand how one could define the other.
'see the detailed requirements' is the second definition.
Although both the answer and definition are singular nouns, I don't understand how they can define each other.
'you' is the link.
Can you help me to learn more?
(Other definitions for specs that I've seen before include "what builders are doing?" , "Do they help one to see" , "Instructions" , "you can see right through them" , "shades?" .)
