Xenoglossy

Xenoglossy is a science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Xenoglossy rather than just read about it. In short: Xenoglossy (), also written xenoglossia () and sometimes also known as xenolalia, is the supposedly paranormal phenomenon in which a person is allegedly able to speak, write or understand a foreign language that they could not have acquired by natural means. The term derives from the Ancient Greek xenos (ξένος), "foreigner" and glōssa (γλῶσσα), "tongue" or "language".

Key takeaways

  • Xenoglossy belongs to science; place it in that map before memorising details.
  • Learn the definition first, then one example that makes the definition concrete.
  • Connect Xenoglossy to a quantity you can measure, compute or draw — that is where exam questions come from.
  • Reproduce the core statement of Xenoglossy from memory before moving on to harder problems.

Reference excerpt

Xenoglossy (), also written xenoglossia () and sometimes also known as xenolalia, is the supposedly paranormal phenomenon in which a person is allegedly able to speak, write or understand a foreign language that they could not have acquired by natural means. The term derives from the Ancient Greek xenos (ξένος), "foreigner" and glōssa (γλῶσσα), "tongue" or "language". The term xenoglossy was first used by French parapsychologist Charles Richet in 1905. Accounts of xenoglossy are found in the New Testament, and contemporary claims have been made by parapsychologists and reincarnation researchers such as Ian Stevenson. Doubts have been expressed that xenoglossy is an actual phenomenon, and there is no scientifically admissible evidence supporting any of the alleged instances of xenoglossy. Two types of xenoglossy are distinguished. Recitative xenoglossy is the use of an unacquired language incomprehensibly, while responsive xenoglossy refers to the ability to intelligibly employ the unlearned language as if already acquired.

Christianity This phenomenon is mentioned in Acts of the Apostles chapter 2 at Pentecost, when the first disciples of Jesus Christ, gathered together, numbering one hundred and twenty, and of the tongues of fire landed on each of them, formalizing the coming of the Spirit in an episode of inspired communication that allows the disciples to express themselves in languages other than Galilean and to be understood by strangers. Several accounts of miraculous abilities of some people to read, write, speak or understand a foreign language as mentioned in the Bible have been related in similar Christian accounts in the Middle Ages. Similar claims were also made by some Pentecostal theologians in 1901.

Spiritualism Claims of mediums speaking foreign languages were made by Spiritualists in the 19th century. More recent claims of xenoglossy have come from reincarnation researchers who have alleged that individuals were able to recall a language spoken in a past life. Some reports of xenoglossy have surfaced in the popular press, such as Czech speedway rider Matěj Kůs who in September 2007 supposedly awoke after a crash and was able to converse in perfect English; however press reports of his fluency in English were based entirely on anecdotal stories told by his Czech teammates. Xenoglossy has been claimed to have occurred during exorcisms.

Notable claims

Ian Stevenson Canadian parapsychologist and psychiatrist at the University of Virginia Ian Stevenson claimed there were a handful of cases that suggested evidence of xenoglossy. These included two where a subject under hypnosis could allegedly converse with people speaking the foreign language, instead of merely being able to recite foreign words. Sarah Thomason, a linguist at the University of Michigan, reanalyzed these cases, concluding that "the linguistic evidence is too weak to provide support for the claims of xenoglossy".

When Stevenson investigated an American housewife known as "T. E" who exhibited the male personality of a Swedish farmer named "Jensen Jacoby" while under hypnosis, he reported that the subject was able to converse in Swedish, albeit not fluently. However, Thomason's reanalysis concluded that "Jensen" could not convincingly be claimed to speak Swedish; writing that though "Jensen" had a total vocabulary of about 100 words, "this is not very impressive when compared with the thousands of words known by any native speaker of any natural language, even taking into account the limited contexts in which Jensen spoke Swedish." Thomason found that "Jensen" gave no complex sentences, mostly giving one or two word answers, and concluded, "[Stevenson's] demonstration that there was no fraud in the case is convincing, but his claim that Jensen had the capacity to speak Swedish is not." Linguist William Samarin drew the same conclusion as Thomason. Stevenson investigated another American woman named Dolores Jay who exhibited the personality of a German teenage girl named "Gretchen" while hypnotized. He claimed that the subject was able to converse in German. Thomason's reanalysis, while acknowledging that the evidence against fraud was convincing, concluded that "Gretchen" could not converse fluently in German and that her speech was largely the repetition of German questions with different intonation, or utterances of one or two words. Thomason found that the German vocabulary of "Gretchen" was "minute" and her pronunciation was "spotty", adding that Dolores Jay had some previous exposure to German in TV programs and had looked at a German book. William J. Samarin, a linguist from the University of Toronto, argues that Stevenson interacted with linguists in a selective and unprofessional manner, noting that Stevenson corresponded with one linguist for a period of six years "without raising any discussion about the kinds of thing that linguists would need to know," and that most of Stevenson's collaborators were "fellow believers" in the paranormal. In a review of Stevenson's Unlearned Language: New Studies in Xenoglossy (1984), William Frawley wrote that Stevenson was too uncritically accepting of a paranormal interpretation of the cases. In one case, a female subject could only answer yes-or-no questions in German, which Frawley found unimpressive. In another, the female subject could speak Bengali with poor pronunciation. Frawley noted that she was raised in the language of Marathi (related to Bengali), had studied Sanskrit from which both Marathi and Bengali derive, and was living in a town with thousands of Bengalis. He concluded: "Stevenson does not consider enough linguistic evidence in these cases to warrant his metaphysics." Psychologist David Lester evaluated Stevenson's cases and wrote the subjects made grammatical mistakes, mispronounced words, and did not show a wide vocabulary of words in foreign language; he thus concluded that they cannot be considered evidence for xenoglossy.

Worked examples

Example 1 — a first encounter with Xenoglossy

Start with the simplest possible case. Write down what Xenoglossy claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Xenoglossy before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Xenoglossy ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Xenoglossy

In research
Xenoglossy appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry
Engineering practice reuses Xenoglossy in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom
Xenoglossy is common in secondary-school and first-year university syllabi. It links to neighbouring topics Paranormal terminology, Parapsychology, Pseudolinguistics, so understanding it makes those chapters shorter.
In everyday life
Look for Xenoglossy outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
