We have a sentence:

I will have wanted to have gone to the party by the evening.

The problem is I don't know which verb the "by the evening" relates to.

If it goes for "will have wanted" then it's like:

(By the evening I will have wanted) to have gone to the party (even before the wanting moment)

If it goes for "to have gone" then I should understand it like:

I will have wanted (by some moment in the future) (to have come by the evening) (even before the wanting moment)

But the matter becomes harder for we can use Future Perfect like a prediction:

I will have wanted (I must have wanted) to have gone to the party by the evening

And here we don't know which part the "by the evening" relates to:

If it goes for "must have wanted" then:

(By the evening I must have wanted) to have gone to the party(even before)

If it goes for "have gone" then:

I must have wanted (to have gone to the party by the evening)(even before the wanting moment)

Am I taking it right?

  • I can't imagine anybody saying that sentence in real life. It makes sense, but both will have wanted and to have gone are rare in speech, and the pairing makes it very rare.

  • But anyway is my logic here right about all these moments? Or there is something I was mistaken in my words? You know, the main problem why I started asking this was: I didn't know if I had to have the pefect form with "by some moment". For example, "I can come by the evening". Is it correct or no? On the one hand we have some moment in the future by which I can come. It's the Future Perfect usage. Therefore this sentence should have "have" like "I can have come by the evening". But if we use "have" it will be about past, not about a possibility to come by some moment in the future... Mar 25, 2019 at 17:30
  • @ Michael Azarenko "I can come by the evening is understandable," but I would most likely say, "I can come by this evening." Not trying to nitpick, but it sounds more natural to me. Of course, in this case, "by" does not refer to time. I'm using it in this way: "I can come by, if you would like."

The sentence as written is ambiguous, so I don't think there is any solid answer to your question.

Option one:

[I will have wanted to have gone to the party] by the evening.

"By the evening" qualifies everything that comes before in this interpretation. A clearer way to write this might be:

By the evening, I'll wish I'd gone to the party.

Option two:

I will have wanted [to have gone to the party by the evening].

This speaks to your desire to attend the party at a particular time ... before (by) the evening. A clearer way to say this might be:

I will want to have arrived at the party before evening.

Apart from the ambiguity of the grammar, the word 'to go' can have many subtle differences in meaning. "To have gone" may be "to have travelled to the party", or "to have attended the party".

There is no way from the grammar of the sentence itself to tell which you mean, so you need to clarify it by rewording.

When you get into fairly elaborate mixtures of future perfect and perfect infinitive, it pays to ask yourself if there is a simpler way to express things.

  • When you say: "I will want to have arrived at the party before evening." you mean when I will want I will have already missed the arrival for the party or the party can be later than the moment of wanting? Because if it's "I want to have done" - the "done" moment was earlier than the "wanting". If it's "I wanted to have done" - again the "done" moment was earlier than the "wanting" one. In the future it's the same? I will want to have done - the "done" moment will be earlier or later then the "wanting' one? What is the difference between: will wan to come\to have come?
