According to Merriam Webster,
Prepone is an Indian English word which means "to move to an earlier time", used as an antonym to "postpone". For example:
"The publication date has been preponed from July to June".
Interestingly, it also mentions that the word is largely unheard outside the subcontinent.
So, my question is, what word or phrase do the natives outside Indian English speaking ones use to imply the same thing ? Is it simply "moved" or something else?
