Presumably, you get this from talking shop with that collective that has a word for everything (10)
I believe the answer is:
vocabulary
'presumably you get this from talking shop with that collective that has a word for everything' is the definition.
The definition suggests a singular noun which matches the answer.
This is all the clue.
Can you help me to learn more?
(Other definitions for vocabulary that I've seen before include "Word list" , "List of words" , "Knowledge of words" , "Range of words" , "Words an individual knows" .)
