The word "de motes" is a rare and uncommon term. It does not have any widely recognized antonyms. This is because it is not used frequently in everyday language, and there are few commonly used alternatives to it. However, if we look at the components of the word, "de" refers to the removal or reversal of something, while "motes" implies a small particle or speck. Therefore, one could suggest some potential antonyms, such as "add" (the opposite of remove) or "clump" (the opposite of small particles). Nevertheless, these may not be directly related antonyms to "de motes" and should be used with caution.
