Why does it says "you can A duet"?

It seems to be an error

It’s just a typo/error.

It should be: "you can do a duet" or "you can be a duet," but the first one makes more sense to me.

It’s a transcription error. There should be a verb between “a” and “duet,” like ‘do,’ ‘sing,’ or ‘perform.’

I think it’s supposed to be “you can do a duet of ‘Ebony and Ivory’ all by yourself.”

Looks like a typo to me, "you can perform a duet" would make more sense. The word "perform" can be swapped out for something else, but there should be a word between "can" and "a".

It’s a typo. The actual line in the show’s captioning is “you can do a duet…”

Yes it is an error, the script says: * [Chandler](https://www.imdb.com/name/nm0001612/?ref_=ttqu_qu): Oh my God! You can do a duet of 'Ebony & Ivory' all by yourself. Are lot of people still learning 90s English by watching Friends? Or is this a meme??

It is likely a typo, but without seeing the actual footage… We are just guessing as to what was really said.

FYI it should be "Why does it say ___?" As others have said, it's an error. It may be an old way of talking or a rural version, but it's unclear. What is this from?

What app is it?

It should be "do a duel" or "perform a duel" a duel sounds off. (What do you expect from an Instagram ad anyways)

It's actually "you can do a duet" the transcription is just wrong. Nothing to learn here except that AI still sucks

Ebony and Ivory was a Dueling Pianos Duet of an Caucasian American and African American Performers; while the sentence is Grammatically Flawed it is implying the Suntan Bed has tendency to burn the skin if one does not roll over every few minutes.

thats a typo

I'm not sure why I keep getting this subreddit recommended to me. English is my first language, and I speak it rather well.

As written, it seems to mean preserve a duet by canning it (sealing it in a jar or can and Pasteurize it). This seems difficult to do to a duet.

it's a typo
