In a cultural rather than legal sense, appropriation usually involves the implicit or explicit erasure of the source culture. The idea of “property” doesn’t apply to culture as it applies to a product. Not to pile on Alison Roman, but she created a “spiced chickpea stew” that resembled a curry—but denied that it was a curry, claiming she “has no culture” in which curry exists. (If this story isn’t familiar, Google can help.) That’s a good example of appropriation, and a way to distinguish it from borrowing, adaptation, acknowledgement, homage, imitation, etc.
