How do I say “Our meeting is preponed”?
A friend of mine asked me this question, and it caught my curiosity.
Is there an explicit opposite of the word postpone? As in, do something in advance? Clearly what I just said is functionally equivalent to the answer I am seeking, but I was wondering if there was a single word that is the antonym.
More context: Bob was supposed to start work in July, but due to a work visa issue, he had to begin in advance.
