When we think of the phrase "spreading on," words like "smearing," "suffusing," and "scattering" might come to mind. But what about the antonyms of this action? If we want to describe the opposite of spreading on something, words like "removing," "erasing," and "extracting" could be used. Alternatively, if we want to express the idea of something not spreading on a surface, we could use terms like "resistant," "repelling," or "invulnerable." These antonyms not only help us to widen our vocabulary but also provide a more nuanced way of communicating our ideas.
