The term "singularize" means to make something unique or distinct from others. However, there are several antonyms to this term, which include generalization, universalization, normalization, typification, and standardization. These words refer to the process of making something common, ordinary, or typical. For example, when we speak of generalization, we mean the act of taking something specific and making it applicable to a broader group of people or things. By contrast, singularization takes something and gives it its own identity or character. Therefore, antonyms for "singularize" are words that imply taking something from the specific and making it more general or less distinctive.
