I've seen "yet" in sentences using the present perfect all the time, but what about the past perfect? Has it ever been used in this tense? Is the following sentence grammatical?

By 2005, I had not yet been introduced to her parents.

If there is any case where "yet" is deployed in the past perfect, I'd appreciate it if you let me know. Thanks a lot!

    Your use of yet is fine, but In 2005 would be better than by. Dec 21, 2023 at 10:58
  • I always thought that we would use the past simple in the case of "in 2005" because the past simple is used to refer to an action happening AT a specific time stamp in the past, while the past perfect refers to an action happening BEFORE the time stamp mentioned. Since by means "not later than/before", I haven't worked out why I can't use it here. Could you elaborate?

    Yet carries the meaning 'by now' or 'by then', so you don't need another 'by'. Dec 21, 2023 at 12:52
