I don't really know much about the Guardians of the Galaxy outside the movie.

When they talk, Rocket seems to understand what Groot means, even thought Groot only ever says "I am Groot".

Is there an in-universe explanation for this?

The question: Why does Groot only say the phrase “I am Groot”? suggests a reason why most people don't understand Groot, but it does not explain why / how Rocket does.

    @Richard not a duplicate of that at all, I'm not asking why Groot says I am Groot, I'm asking how does Rocket understand him... The clue is in the title! – Daft Nov 12 '14 at 10:27

    The other question does not explain why Rocket is so different that he can pick up the subtle nuances. – phantom42 Nov 12 '14 at 11:43

    @Richard, phatntom42's point is valid. I want to know how Rocket understands Groot, not why everyone else does not. – Daft Nov 12 '14 at 11:51

    The OP wants to know as to whether there are any references mentioning as to why exactly is Rocket sensitive to these subtle nuances. It's a perfectly valid question. It is not a duplicate. – Stark07 Nov 12 '14 at 12:28

    Maybe because he's a raccoon and has a close familiarity with trees? – BBlake Nov 12 '14 at 13:35

Because Rocket and Groot have spent a long time together.

As shown in the film, Groot doesn't just say "I am Groot" in a completely dead voice; there's a lot of emotion and expression behind it. You're probably already able to pick out particularly strong emotions: for example, if he's feeling happy, or sad. What marks Rocket apart is that he can pick up nuance which we can't hear.

The idea that Groot expresses complex ideas through intonation is one supported by the comics. Here's a scene from early in Rocket and Groot's relationship, where Rocket is still confounded by "I am Groot", and Maximus the Mad has to explain it to him:

enter image description here

Here's what Maximus says:

The mature dendritic form of King Groot's people is robust and heavyweight. Often, the organs of acoustic generation become stiff and inflexible. It may sound as if he is simply repeating his name, but that is simply due to the hardened formation of his larynx. You must listen to the sigh of breeze beneath it. The nuance of meaning.

So presumably if you're willing to spend time with Groot and listen, you too would be able to understand what he's saying. This isn't a bond unique to Groot and Rocket (such as telepathy). We don't get details, but we know (MCU) Rocket and Groot have spent a long time together, and presumably this was long enough for Rocket to learn to understand Groot's "speech".

The Wikipedia entry for Groot gives the same explanation:

Maximus the Mad, Black Bolt's brother, asserted that whenever Groot is saying the trademark "I am Groot!" he has actually been saying any number of things, and his varying inflections of the sentence are the equivalent of words and sentences. People who have interacted with Groot are gradually able to decipher the meaning of the inflections and can carry on full conversations with Groot as time goes on.

Now that Guardians of the Galaxy: Vol. 2 is out, proof of this can be found in one of its mid-credits scenes which reveals that, by the time of Avengers: Infinity War, Peter too has learned to understand Groot's speech. So it's not anything special between Rocket and Groot; given enough time, anyone with good hearing can learn to understand what he's saying.

    So there is an entire language within the inflections Groot uses when he says 'I am Groot'? I was honestly expecting telepathy or an implant in Rocket's brain... But I guess the inflection-nuance-language-thing is the correct answer! I'll accept it if no one else can produce another one. – Daft Nov 12 '14 at 14:26

    Interesting. I suppose it's like a telepathic species looking at humans and asking "how can they understand each other just by making noises over and over?" Or like the Progenitors from Alpha Centauri, communicating by altering the reverb of whatever noise happens to be occurring at the time. I'd be curious for someone to come up with a "vocabulary" of reverb effects and "breeze patterns" that Groot might be using. – Nerrolken Nov 12 '14 at 17:51

    @Daft: It's not "lazy"; it's an in-joke of sorts. It's intended to be humourous. See also: ST:DS9's Morn. – Lightness Races in Orbit Nov 13 '14 at 10:09

    @Daft: I put "lazy" in quotes because it was a quote. I was quoting you. It was a quoted word. The quotes signify that. No, no reference; it's plainly obvious from the panel in this answer. – Lightness Races in Orbit Nov 13 '14 at 10:24

    @Daft: Yes, in my response to you about it... – Lightness Races in Orbit Nov 13 '14 at 10:36

Rocket and Groot have been together for many years.

He knows Groot better than anyone else.

    This doesn't really explain how he learned Groot's language though. Proximity doesn't equal learning. – Valorum Nov 12 '14 at 13:28
  • @Richard This just suggests that he knows him well enough to know what he'd think without him having to say anything meaningful. In other words, Groot has no (meaningful) language, Rocket just fills in the blanks. Given the comic in alexwlchan's answer, I think this answer is wrong (although a good guess, I suppose). – Tim S.

Rocket is highly intelligent, but he is still not human, or anything similar, as Drax and Gamora are. He isn't even supposed to exist, the result of illegal testing. As a result, he can speak English, learn quickly, is highly intelligent and strategic, and appears mostly human. But remember, he's not. He's an animal. Because of this, Groot and Rocket share an underlying connection to nature. And through this, they can connect.

Or, you know, Rocket has no idea what Groot is saying, and Groot has no idea what Rocket is saying. Rocket just takes his best guess. Seeing as Groot is just as annoying as everything else, he could just be creating a character to fit the tree that follows him around.

    There's plenty of evidence that Rocket can understand Groot. – Valorum Feb 28 '17 at 18:33
