This week received a question about time expressions from Dara in Cambodia. He asks,Do you use the phrase "last Tuesday?"If so, what does it mean? Does it mean "on Tuesday last week" or "on Tuesday this week?"I have the same question for "next Tuesday." Thank you. - Dara, Cambodia.Dear Dara, That is a great question.Even native English speakers can misunderstand these expressions."Last" and "next" are both adjectives.When we use them with a day of the week, their meaning can change depending on the time we are speaking."Last" means the most recent.If today is Wednesday, and I tell you, "I talked with her last Tuesday," you might think I meant I talked with her eight days ago.The reason is if I had talked with her only one day ago, I would have said, "I talked with her yesterday."So, when I say, "I talked with her last Tuesday," I mean the Tuesday of the week before.Now imagine that today is Thursday or Friday.
