Most oversoon is an uncommon term that means too soon or prematurely. Its antonyms would be delayed, late, or overdue. To delay is to postpone or put off something to a later time than initially intended. Late, on the other hand, refers to something occurring after the expected or planned time. Overdue implies that something has taken far too long to happen, often beyond the acceptable or expected time frame. Using the antonyms, we can construct sentences such as 'The meeting was delayed due to unforeseen circumstances,' 'His flight was late, causing him to miss his appointment,' or 'The overdue report was finally submitted after weeks of delay.
