Characters like R2-D2 (Star Wars), Chewbacca (Star Wars) and Groot (Guardians of the Galaxy) share the attribute that they speak a language unintelligible to viewers and readers - we have no idea what they say - yet they have no problems communicating with other characters who speak English (or whatever is the primary language of the story).

Which Sci-Fi work introduced this concept?

  • The character speaking an unintelligible language must be a main character, and must be non-human (e.g. an alien or robot).

  • We must be able to understand the other characters.

  • Other characters must be able to converse with this character.

In other words, the dialogue, to the audience, must be one-sided.

    I had hard time phrasing the question. If you can phrase it better way and more concisely, please edit it. – Lobo May 9 '17 at 21:39
  • I took a stab at the last point, but I probably invalidated the Peanuts answer. If it doesn't work for you, feel free to roll back – Machavity May 9 '17 at 22:35

In the comic Peanuts, Snoopy was always able to understand what his bird friend Woodstock was saying, though the reader had not a clue.

Wikipedia gives the date of Woodstock's appearance as April 4, 1967.

Although Cousin Itt, from the TV show The Addams Family is apparently older.

The Addams' Family was on TV starting September 16, 1964, but Cousin Itt did not appear until approximately a third of the way into its run. Since it ran to April 8th, 1966, that means he likely appeared in 1965.

There was an eponymous episode "My Fair Cousin Itt" that aired on September 11, 1965, but he probably appeared before that.

    I was curious so I looked it up - Peanuts started in 1950, Addams Family in 1938, FYI. – Steve-O May 10 '17 at 0:28

    @Steve-O Since the question asks about for the earliest example, answers should include dates. Peanuts started in 1950 but Snoopy started making friends with birds in the early 1960s and the bird character Woodstock first appeared on April 4, 1967. As for Cousin Itt, I don't think he was shown speaking gibberish before the TV series. – user14111 May 10 '17 at 2:37

Tinkerbell could be an earlier example.



From what I understand the text at Project Gutenberg is from the 1911 novel.

Wikipedia also describes for the role of tinker bell in the 1904 play:
