When trying to convey the concept of making something universal, there are several different words that can be used in place of "universalise." One common synonym is "standardize," which implies that a specific set of standards or rules has been established and applied across the board. Another option is "generalize," indicating that something has been made applicable to a broad range of situations or contexts. "Globalize" is also a possible substitute, conveying the idea that something has been expanded beyond its original boundaries to encompass the entire world. Ultimately, the specific word choice will depend on the context and intended meaning of the phrase.
