Item #: SCP-5780
Object Class: Euclid
Resting place of Professor Natalya Petrova. Foundation researchers are attending a lecture on the evidence of past CK-Class Restructuring Scenarios present in the lexicon and grammar structure of several languages, particularly languages isolates.
Special Containment Procedures: The process by which to access SCP-5780-S is restricted to the Foundation's Department of Unnatural Languages and to senior researchers of key SCP objects. The realization of SCP-5780 is expressly forbidden outside of a completely soundproofed environment, with noise-cancelling equipment being mandatory to all supporting staff and security. Under no circumstances should D-class personnel be taught how to access SCP-5780-S for the purpose of testing, and only Foundation linguists scoring high in standard loyalty tests may be allowed to study any part of the realization of SCP-5780.
Since 03/13/20██, Protocol Gatlathan may be used to track the continued loyalty of SCP-5780 linguists, and has been adopted as a common greeting between senior Foundation staff in private environments. Protocol Gatlathan is a "three way handshake" protocol between two individuals capable of realizing all of the phonemes in the SCP-5780-W word Gatlathan. While impossible to ensure under informal settings, the official routine execution of Protocol Gatlathan must be initiated by the person whose loyalty to the Foundation is under question. See Interview Log 5780-Gatlathan for a transcription of Protocol Gatlathan. Tentative cross linguistical etymological analysis has determined that the word Gatlathan would narrowly be defined as both "loyalty" and "family."
Due to both the anomalous nature of SCP-5780-S and the difficulty in naturally producing an instance of SCP-5780, knowledge of it is rare outside of the Foundation. Civilians aware of SCP-5780 in any capacity are to be amnesticized. Any building in which death by SCP-5780 is verified to have occurred is to be soundproofed and sealed off from civilians, and any "haunted house" story arising from the propriety to be suppressed, preventing public interest from gaining traction. Should a death occur outside, a building must be constructed in place to house the vocalization.
The tongue's apparent shape while realizing necrophoneme ƍ. This is an optical illusion caused by approaching SCP-5780-S.
Description: SCP-5780 is a set of phonemes or necrophonemes. Like non-anomalous consonant phonemes, SCP-5780-1 through 32 are realized by the obstruction of the vocal tract by one or more speech organs, and differ amongst themselves mainly by voicing, airstream mechanism and the manner of their articulation. Unlike non-anomalous phonemes, their place of articulation is an extra-spatial speech organ of unknown composition (hereafter referred to as SCP-5780-S), theorized to be present in all human beings. SCP-5780-0 is a vowel produced when the tongue is positioned in SCP-5780-S space.
Utterances which contain a SCP-5780 sound will cause different phenomena to occur to the speaker, the listener, and to the location it was spoken. Both the speaker and any listeners will emaciate rapidly and expire with prolonged exposure, with the rate of this change increasing as more force is put into the enunciation. Death by or during the realization of SCP-5780 will not stop speech or vocalization: a disemboweled voice will appear to echo on the enclosure or proximities of where it is being spoken for an indefinite (whose theoretical upper bound is infinite) period of time, and the voices of deceased listeners may be reported to intermittently sob, laugh or murmur until the main speech concludes. It is theorized that each person's SCP-5780-S is responsible for these events.
As the anomaly is believed to be produced by SCP-5780-S and not from the physical sound generated through it, recordings of live utterances fail to reproduce any of SCP-5780's effects.
SCP-5780-W and SCP-5780-L are described in Addendum 5780-Panini.
Voluntary euthanasia by SCP-5780 is to be permitted for Foundation linguists and senior researchers to study long term exposure to its effects, and Foundation personnel may take one-hour weekly visits to the resting places of these individuals, provided that they receive physical examination and clearance from a Foundation doctor as being fit to do so.
Discovery: The knowledge necessary to realize SCP-5780 was developed by the metaphonetics division of the Department of Unnatural Languages on the aftermath of Incident 5780-A.
Following directive Panini's Ghost, the Department of Unnatural Languages laxed restrictions on intradepartmental research of SCP-5780. Experimental lexicologists developed a vocabulary of neologies containing a combination of SCP-5780 necrophonemes with non-anomalous phonemes. These words are informally described as antiwords, and hereafter as SCP-5780-W.
SCP-5780-W will induce the speaker's perspective or current understanding of the antiword's "subject" onto the listener, such that no two utterances of SCP-5780-W may ever be understood to have exactly the same meaning. Listeners that have no experience with SCP-5780-W will literally feel the described perspective as their own. A selected sample of tests on the capacity of semantic transmission is maintained in Experiment Log 5780-Huang by Site Director Huang. Of note is that two interlocutors may have a productive conversation by repeating the same antiword to each other for minutes; this is because of the additional meaning being added to that person's understanding of the antiword.
An yet unknown grammar has been suggested to exist that would allow the speaker to build complex antisentences carrying the same properties as individual SCP-5780-W (that is, the resultant meaning of the full utterance would be induced to the listener); such a language would be termed SCP-5780-L. The hyperlanguage invented or described by Professor Petrova and Dr. Huang has been widely accepted by Foundation linguists to fit that criteria, with some controversy as to its theorized limitations.
By definition, any transcription or recording of SCP-5780-W, SCP-5780-L and Petrova-Huang hyperlanguage (collectively hereafter Superset-5780) will fail to record the meaning induced to the listener, producing only the phrase from which to obtain it from the original speaker. For this reason, Superset-5780 has been described in Foundation literature as empathic, antisymbolic or subjectively pure. Translation is the only method by which to record the meaning obtained from Superset-5780 utterances outside of live speech, thereby subjecting it to the inaccuracy of non-Superset-5780 languages.
A hyperlanguage family consisting of SCP-1206-A, SCP-1220, SCP-1390, SCP-4179 and Petrova-Huang hyperlanguage (following the rediscovery hypothesis) has been proposed by Dr. B. Kenneth, Dr. Y. Cheng, and Dr. A. Das of the megahistoric linguistics division, whose protolanguage would have had given several loanwords to Old Daevite, Old Adytite (by Daevite superstratum) and Old Asurite.

Distribution of the languages and dialects of France after the Sorbonne Incident.
██████ed intel listed the P██████ Residence as a top priority Marshall, Carter and Dark propriety. █████ngly to the Foundation, A██████ Carter, estranged son of Robert Carter, had been living together with his family in the P██████ Residence since 19██, from which point the propriety was dropped off from all MC&D ledgers and records.
Between 19█2 and 19█5, the SCP Foundation broke previous cooperation treaties and waged a secret war against Marshall, Carter and Dark Ltd, its holdings, subsidiaries and members over the fallout of the Sorbonne Incident. A commercial blockade was forced upon MC&D Ltd by the enactment of doctrine "Secure, Cease and Desist": ███ major companies were affected and ██ closed down, having their assets liquidated by the Foundation. O5-05 hastily authorized the execution of all pre-planned conventional retaliatory strikes on known MC&D assets to cripple their influence on world leaders. █ governments were toppled during this period. O5-05's quick initial action has been praised for succeeding in the primary goal of reestablishing the veil.
Mobile Task Force ██-█ ("████ ████████") was dispatched to the location of the P██████ Residence where they ███████dly found and apprehended A██████ Carter together with his family. After MTF-█-6 reported the situation up the chain of command back to █████ in an exceptional breach of protocol for ████████ing orders, an altercation broke out in which A██████ Carter, C████████ Carter (daughter), J███ Carter (son) and S██████ Carter (daughter) were shot and killed. His wife, M████ Carter was not present at the scene and arrived shortly after in the living room, at which moment she spontaneously began to vocalize SCP-5780-0 at a high volume and was shot by MTF-█-4, before himself collapsed and expired by continued exposure to SCP-5780 along with the remainder of MTF ██-█. Containment procedures were shortly after enacted; however, due to the P██████ Residence's prominent position in New ████ and the constant vocalization of SCP-5780-0, concerns about long term containment were raised.
M████ Carter remained to scream for the entirety of the 19█2-19█5 conflict. Maintenance crews entering the P██████ Residence after April of 19█2 reported that vocalizations of SCP-5780-0 were now sporadically intertwined with a call-and-response pattern between M████ Carter and members of MTF ██-█ through the yelling of a then unknown word, now identified as the first recorded utterances of "Gatlathan."
After open hostilities ended in 19█5, the Overseer Council accepted that, in a 12 to 0 vote (one overseer abstained), it would be in the mutual interest of the SCP Foundation and MC&D Ltd to allow Robert Carter's request to enter the P██████ Residence with his former wife and bury the Carter family. Since 19█5, the original occurrence of SCP-5780 has been considered neutralized.
