The spelling of the word "postpontile" is a bit complex. The word is pronounced as pohst-pon-til, with emphasis on the second syllable. It is important to note that the letter "t" in the middle of the word is silent, making it tricky to spell. The "e" at the end of the word is added to indicate the adjective form of the word "postpone". "Postpontile" refers to something that has been postponed, delayed or rescheduled.
