Ides is a plural noun used in historical and calendar contexts to refer to mid-month days in the Roman calendar (the thirteenth or fifteenth day, depending on the month). In modern usage it appears in phrases like “the Ides of March,” often signaling a notable or ominous point in time. The word is pronounced with a short, clipped first syllable and a clear “d” followed by a long “ee” sound in the second, all without extra vowel sounds.
