Professional workshop equipment gets around 100 procedures (9)
I believe the answer is:
protocols
'100 procedures' is the definition.
The answer and definition can be both related to communication as well as being plural nouns.
Perhaps they are linked in a way I don't understand?
'professional workshop equipment gets around' is the wordplay.
'professional' becomes 'pro' (synonyms).
'workshop equipment' becomes 'tools' (I can't justify this - if you can you should believe this answer much more).
'gets' means one lot of letters goes inside another (gets can mean captures or absorbs).
'around' becomes 'c' (abbreviation for 'circa').
'tools' enclosing 'c' is 'tocols'.
'pro'+'tocols'='PROTOCOLS'
Can you help me to learn more?
