My example is a plate of food that looks like cookies, but are actually savory and tomato-basil flavored. Supposing that it's agreed that calling them "cookies" is incorrect (maybe debatable also), is there a word for incorrectly calling them cookies solely because they look like cookies?
I thought of the word misnomer, which could apply here. But that's just a general term and doesn't take appearance into consideration. I also thought of malapropism, but that's more of a humorous misusage of a word, and doesn't really apply here. I searched this wonderful site and ending up going down the rabbit hole of iconicity, but that's not what I'm looking for.
So I'm wondering if there's a word for calling something the wrong name based on how it looks?
