Hello, I am not a teacher,
but I think like in French, we must consider the new word like one word.
We have the same thing in French language, two words connected by an hyphen, and we consider it like one word. Sometimes with the time, at the beginning we had the hyphen and with the evolution of language the hyphen has disappeared.
I think it's the same in your own writting system.
Have a nice day from France, see soon on the site.
