Challenge: write a sentence that contains the phrase "is have been"

> In reverse alphabetical order, the words "been have is" would be "is have been". 

While we are being pedantic, in this case “is have been” isn’t a PHRASE. You’re asking for a sentence that has the three words in that order but it’s not a phrase that in itself has meaning.

Is have been in the past tense or present perfect?

They like what the song is, have been telling everybody about it, and are now listening to it again.

The definitions of what a good person *is have been* changing since the beginning of time.

A redditor made a strange post asking for commenters to use the phrase "is have been" in a sentence.

Everyone has been thinking about what it isn’t, but those that have been thinking about what it is have been making progress on a solution.

Some of these syntaxes didn't even occur to me! The English grammar is SO flexible.

Is "have been" a verb form?

>!The people who know where it is have been nowhere to be seen.!< I’m an English native. It took a second but I did it

>!The researchers who figured out what it **is have been** disappearing mysteriously.!< Took me a sec! It's not a very common combination of words, since there's usually a more concise way to say the same thing (at least in my example)

All the people who overuse the word is have been scoring lower on their essays. Idk if that’s grammatically correct tho, I feel like I should put is in quotation marks or something.

Both who he wants to be and who he **is, have been** changed for good

Why? This phrase doesn't make sense unless you want people to write something extremely convoluted.
