Is there any way that I can use in adjective + noun for the following meaning? I want to talk about "the teacher that was a substitute" but this way seems to me long, unnatural and wordy.
Can I say for example "substitutable teacher" and the the meaning will still remain?
Context: Jack, a substitutable teacher, went on the street and then he noticed to strong voice behind him..."
Another example: "I saw the substitutable teacher last week"
