For example, in the noun "victim-blaming", what is the "blaming" part called? Is it some special type of verb, or perhaps something else?
Words of this form can generally be made up and can still be understood in casual speech and writing, like "tantrum-throwing" or "cigarette-smoking" (as adjectives, for example). I want to know what the -ing verb portion is called.
I am looking for something that indicates it is a verb but also indicates that it is part of a compound noun or adjective (and not just a standalone verb in the sentence).
