Transliteration mystification
« previous post | next post »
From the Wikipedia page on Pafnuty Chebyshev:
The surname Chebyshev has been transliterated in several different ways, including Tchebichef, Tchebychev, Tchebycheff, Tschebyschev, Tschebyschef, Tschebyscheff, Čebyčev, Čebyšev, Chebysheff, Chebychov and Chebyshov (which provides the closest pronunciation in English to the correct pronunciation in old Russian). Chebychev is an erroneous mixture between English and French transliterations. In English, the transliteration Chebyshev has gained widespread acceptance. The correct transliteration according to ISO 9 is Čebyšëv. The American Mathematical Society adopted the transcription Chebyshev in its Mathematical Reviews.
A count of 14 seems on the high side for the description "in several different ways".
I believe this is the densest thicket of transliterations I've ever encountered, though internet search does the right thing with all the variants I've tried, e.g. Čebyšëv polynomials.
What reminded me of the problem:
At the stage of rewriting some inherited lecture notes at which I need to (a) pick a transcription of Чебышёв and (b) explain to the students where else in an index they might have to look.

I've always used "Chebyshev" in my own lecture notes without giving it a second thought, e.g. here, though my usage is banal enough that I doubt many readers feel the need to investigate beyond the hyperlink that I provide. And anyhow, few students these days are likely to use a paper-book index, rather than internet search.
Update — For a real example of transliterational mystification, at least as it used to be, see Victor Mair's 2017 post "Sinological suffering".
Update #2 — A common source of transliteration confusion is what happens when a surname passes through several languages with different orthographic systems, as well as also several dialects with different pronunciations. For example, my mother's family name is "Yoffe" in its U.S. version, apparently assigned on Ellis Island when her (Russian) parents immigrated in 1921. Other latin-character variants include "Ioffe", "Joffe", "Yaffe", "Jaffe", "Jaffee". All of them come from Hebrew יפה, perhaps filtered through Cyrillic Ио́ффе.

It may be that ‘Chebyshev’ has a dense thicket of transliterations, but the only one I’ve ever seen in my work is ‘Chebyshev’, and the most common usage is probably in ‘Chebyshev‘s theorem’, because of its ubiquity in basic and advanced stat classes.

All dozen variants given seem to agree in transliterating the first syllable's е as e, although the final syllable's ё as input give more variation in output. It makes me wonder whether it's possible to come up with a Russian word spelled solely with Cyrillic glyphs that cause variant output in different transliteration approaches such that you could come up with a dozen different cromulent romanizations without any single glyph consistently present in all of them.
I am reminded of the late James McCawley's piece "Thirty Million Theories of Grammar," premised on the notion (if my hazy memory is accurate) that there were at least 25 different methodological questions in syntax where there were at least two legitimate approaches and a given scholar's answer to any one of the questions was logically independent of the same scholar's answer to any of the others. So two-to-the-25th-power rounds down to 30 million as the number of possible combinations.

Хрущёв and Горбачёв never got the dieresis in transcriptions.

The surname of probably the most famous Russian composer of classical music got firmly entrenched as "Tchaikovsky" in English long before the modern standardization of transliteration from Cyrillic. However, back in 1969 I spent about six months working in the music library of what was then Radcliffe College, which had a policy of using "official" transliterations of Russian names, with the result that I often had puzzled students coming to the desk saying they couldn't find anything by that composer, and I had to explain that he was alphabetized under C.

I remember Prof. Liberman also listed an impressive number of spellings for Qadafi back when there was a reason to write about him. Maybe not as impressive as Чебышёв.

Tom Körner notes "His preferred transliteration seems to have been Tchebycheff, but he has been overruled." (from An Introduction to Fourier Analysis), and the "T" is why his polynomials are T_n. (Incidentally Körner himself uses "Chebychev").
Not surprisingly, the ambiguity of this particular romanisation to have been a topic of discussion for some time: there were some letters published in IRE Transactions on Circuit Theory in 1955 discussing it.
Thankfully at least this one has settled to the near-consensus now (unlike some less commonly used surnames: Kondrachov/Kondrashov and Ermakov/Ermakof/Ermakoff are two mathematicians I've dealt with recently where several variants are common).
(Sorry if the link syntax is wrong, I don't comment here much.)

Anyone interested in this topic should find a copy of The Thread: A Mathematical Yarn, by the mathematician Philip J. Davis. In the Introduction to the second edition (1983), he writes:
If you like that paragraph, you will probably like the book, which takes off from the very issue featured in this post. From ch. 1, "Tschebyscheff":
Much of the remainder of the book grows from that seed. As for the wonderful name Pafnuty, he has a chapter on that too, beginning:
He finds himself perusing a copy of Ecclesiastical History ("by one Socrates Scholasticus") and:
And off he goes. It's a wonderful book.

Contrary to a widespread belief, no one's name was changed or assigned at Ellis Island, with one notable exception discussed in the article below. "Yoffe" would have come from a manifest supplied to the officers by the steamship line.

Ripley's Believe It Or Not once claimed that the name Shakespeare could be spelled over 800 different ways. I don't remember the exact number, but it seems rather high. Has anybody ever complied the list of all the different spellings?
I asked Microsoft Copilot about and the reply was that there were nowhere near that many spellings. Copilot gives a link to David Kathman’s survey on The Shakespeare Authorship Page, which gathers all known spellings from printed and manuscript sources. It does not approach hundreds.

Anyone studying aerodynamics in English has had to learn that Zhukovsky = Joukowsky. English Wikipedia's biographical article for him is titled "Nikolay Zhukovsky", while the mathematical ones are titled "Joukowsky transform" and "Kutta–Joukowski theorem".

Further to Davis as quoted by languagehat, wikipedia helpfully explains that "The Greek name Paphnutius (Παφνούτιος) takes its origin in Egyptian pa-ph-nuti ("the [man] of God" or "that who belongs to God"; see the Coptic name "Papnoute"). The name entered Russian as Пафнутий (for example, the famous mathematician Pafnuty Chebyshev)."
The nitpicker-or-purist may of course dissent from the Latinizing rendering of Παφνούτιος as "Paphnutius" and insist on "Paphnoutios."

The various listed transliterations only reach that high a number because it includes German, French and (I presume) Serbo-Croat alternatives. No English person translating his name is going to put in Tschebyscheff.
Why not go all the way and add in Japanese Hiragana? If you really want to mess with people, you could add ones like Maori that really drift, because it has almost none of the sounds of the original (Keripetepi or similar). They make about as much sense as including French versions and, even odder, deprecated French versions.
Realistically, in English, you need to decide between Chebyshev, Chebyshov or, my preferred, Chebyshëv. None of which cause major issues when recognising the name.

The Greek name Paphnutius (Παφνούτιος) takes its origin in Egyptian pa-ph-nuti (‘the [man] of God’, or ‘that who belongs to God’. “Nuti” does not refer to the Sky-goddess Nwt but to nṯr [nečer > neter ‘god’]. The Coptic name “Papnoute” ⲡⲁⲡⲛⲟⲩⲧⲉ, papnoute (pꜣy-pꜣ-nṯr ‘belonging to God’ or ‘he of God’; the symbol Ꜣ might represent [a]) was adapted into Arabic as Babnouda, which remains a common name among Copts to this day. It was also borrowed into Koine Greek as Παφνούτιος (Paphnutius), which, in turn, is the source of the Russian name Пафнутий (Pafnuty), perhaps best known in the name of the mathematician Pafnuty Chebyshev [or Chebyshof].

I was not familiar with the mathematician, but if I were guessing at a pronunciation of his name, I'd have thought that the "ы" in Чебышёв would have drawn the emphasis to the second syllable (I assume that the "ё" in fact propels it to the last). Unaccented ы is rare, isn't it? And, to my non-native ear, hard to pronounce. (Also, the given name Pafnuty [Пафнутий] is one I've never seen before.)

Does the following approach cover all potential English transliterations of Чебышёв?
Ч : { Č, Ch, Tch, Tsch }
е : { e }
б : { b }
ы : { i, y }
ш : { č?, š, sh, ch, sch }
ё : { e, o }
в : { v, f, ff }
That gives 4×1×1×2×5×2×3 = 240 combinations based on the variations seen in the examples list from the beginning of the post.
But now I've just gotten to reading the comment by Chester Draws, and it seems that surely I've overcounted due to mixing in alternatives from non-English romanization schemes.

Since the subject is transLITerations, I guess one really should refer to e.g. "French-informed Roman-letter" representations and the like, parallel to e.g. "Mandarin-informed Chinese-character" transliterations. Such things, while "X-informed," can of course still get footholds in not-X-speaking environments, often resulting in weirdness/confusion (for some)…

In answer to Robert Coren's comment – I was a librarian here in the UK for many years. At one time (I think in the late '80s) there was a policy in the cataloguing co-operative that we belonged to of enforcing 'correct' transliteration from Cyrillic, so Tchaikovsky had to become Chaikovski'i. It caused so much confusion that eventually the rule was relaxed in his case. (I don't know at what date Tchekhov became Chekhov, but readers seem to have accepted that one!)

Paphnuce is the name of the monk in Anatole France's Thaïs. Massenet, in his opera, changed it to Athanaël, no doubt for musical reasons.

Because English-language writing frequently uses Tschebyscheff and never uses hiragana.
Unaccented ы is rare, isn't it?
Not in the least. To take a common example, the plurals of feminine nouns in -а end in -ы (or -и with certain consonants), so the plural of (e.g.) карта is карты.

The trick here is that German and French were used so much in academic writing, including in Russia itself, that many Russian names of persons and places reached English in German or French transcription. Tchaikovsky is a French transcription (except that French uses ï without exception); and the letter languagehat quoted above features an example of someone using Tschebyscheff in English for years.
The "Serbo-Croat alternatives" are also the Slavicist ones; that's why they, too, have been used in English, especially by people who tried to go for standardization – ISO 9 is mentioned above.
Correct. Ё is always stressed except when it's used to transcribe Japanese.
That's just a question of practice. By now I don't find it harder than [ɪ].

ё : { e, o }
ё : { e, o, yo, ë }
[the last of those is Latin e with diaeresis, and is sometimes chosen for visual similarity]
There are probably other options. In fact ё after ш is always pronounced the same as о, so "yo" is redundant/misleading in this context, but is sometimes used anyway.
(I wonder if anyone used to the confusion around Chebysh(e/o)v had applied the same "correction" to the name of the Russian footballer Denis Cheryshev, which looks like it should be pronounced almost identically, but in fact has no ё and initial stress.)
Correct. Ё is always stressed except when it's used to transcribe Japanese.
Or Korean or Hungarian or Yakut or… actually there are surprisingly many such cases.
(Or in a few native compounds, such as трёхлетний. But that's even rarer.)

Sixty years ago I had a book called The Soviet Union in Facts and Figures, which I bought for a very modest price from the Soviet Embassy in London. One thing that struck me was that it always transliterated ёв as ov or yov, most notably in Khrushchov, a name that came up often in the 1960s. I assumed that that was the official Soviet transliteration.
David Marjanović said,
August 21, 2026 @ 11:14 am
And then there's the spelling rule that о is never used after ч and щ – ё is used instead, giving us Горбачёв and Хрущёв. (…Those two got -ev in English but -ow in German.)
There we can waffle about secondary stress. :-)

From Packard 2021 ‘A Social View on the Chinese language’: (keep in mind that this is merely a theory, meant to be criticized and improved upon)
At present, most Chinese words consist of two syllables, but those two syllables are no longer primarily the free words that make up compounds, but are mostly either bound roots or affixes.10 So in terms of linguistic morphological typology,11 Chinese has shifted from being a fusional language (from proto-Sino-Tibetan to proto-Chinese) to an analytic, isolating language (from proto-Chinese to Old Chinese) to being an agglutinative, compounding language (Middle Chinese to Modern Mandarin), and now appears to be cycling back in the direction of becoming a fusional language, with the development of derivational and inflectional morphological processes.

Along with indices, one may have to overcome other challenges when trying to find works by people with non Latin alphabet names. For example, when I was working at the music library in college, we had one of those running jokes that became so common that it lost its original humor and just became the way we said it: a composer nicknamed Woktakobny. As in – I left that score on the cart next to Woktakobny. And who was that? The unfortunate Шостако́вич, of course.
