For example, a carpenter works in carpentry and a plumber works in plumbing. So what trade does an electrician work in? Electrical?
I searched the definition for "electrical" and found that it gives the part of speech as an adjective and not a noun like the dictionary does with carpentry or plumbing.
This is confusing to me.
I would like to understand and know how to talk about the trade for an electrician.
I would appreciate it if someone could help clarify and explain this to me.
