I'm trying to understand whether the two adjectives in this sentence are acting as cumulative adjectives (no comma; different categories within Order of Adjectives) or coordinate adjectives (takes comma if "and" can be placed between the two and adjectives belong to the same category). Could you please help?
Her throw of words was like a gigantic freezing shower.
I think these are cumulative adjectives as "gigantic" refers to "size" and "freezing" refers to "observation or opinion" within the Order of Adjectives. Am I thinking right? In which case, should there be no comma?
