Anathematising is a strong word that means to curse, condemn or denounce something or someone. However, there are a few alternative words that can be used in its place. One possible synonym is excoriate, which refers to harshly criticizing or condemning someone or something. Another option is malediction, which is a slightly more formal term that means to curse or speak ill of someone. For those looking for a more colloquial synonym, they may consider the term vilify, which means to speak or write about someone in a highly critical or negative way. These synonyms can help to provide writers with a greater range of words to express their sentiments about a particular topic or person.
