Almost none. We compared all 2,208 words in our course across 22 languages, and
only one, pizza, is recognisably the same in every one of them. Taco is
the same in 21, and yoga, cricket and kiwi in 20. Just 72 words
(3.3%) are shared by 15 or more of the 22 languages.

Even pizza is not spelled the same everywhere: it is пицца in Russian, πίτσα in Greek, ピザ in Japanese,
피자 in Korean, 比萨 in Chinese, بيتزا in Arabic and פיצה in Hebrew. Written in Latin letters, all of them
stay close to “pizza”. Chinese is the narrowest match: bǐsà differs from pizza only in its first sound, which
is exactly one letter at our cut-off.
Look at what is on the list. Most of the top 24 are foods, sports and games, or modern inventions like the
radio and the microphone. When something new spreads around the world, its name tends to travel with it.
Older, everyday words mostly stay inside one language family: water is shared by just four languages
(Polish, Czech, Russian and Serbian all say voda or вода), and 370 words in the course
are not shared by any two of the 22 languages at all.

Spanish and Portuguese are in a league of their own: 959 of the
2,208 words (43.4%) are the same or nearly the same, like señor and senhor or
ahora and agora. The next closest pairs are Spanish and Italian (28.4%), German and Dutch
(25.8%) and Italian and Portuguese (25.1%).
The family blocks show up clearly: the Romance languages share with each other, so do the Slavic ones
(Polish and Czech 19.9%, Czech and Serbian 19.5%), and so do the
Germanic ones. An average pair of languages shares 5.9% of the course.
A few pairs cross family lines. Turkish shares more words with Romanian (207)
than with any other language. Both borrowed widely from French, and it shows: bej and bej (beige), pantolon
and pantalon (trousers), kolye and colier (necklace). Arabic’s closest match is Turkish
(87 words), which took many words from Arabic, such as merhaba (hello) and fil
(elephant). Japanese and Korean share 93, many of them the same English
loanwords written in each script: menu, sofa, guitar. Chinese is the most distinct language
in the set: its closest partner, Korean, shares just 19 words, and with Arabic it
shares 2.
How many words an English speaker already recognises
Words an English speaker can already recognise, out of the 2,208 in our course.
If you speak English, Dutch gives you the biggest head start: 417 of the
2,208 words (18.9%) look almost the same as the English, like vriend (friend) and
minuut (minute). Swedish (387) and French (365) come next.
French ranks that high because English took so many words from it: describe and décrire, accept and accepter.
Japanese (79) and Korean (58) borrow many English words, but they get
reshaped by each language’s sounds, so マットレス (mattoresu) still counts for “mattress” while many others
drift past our cut-off. Chinese usually builds a new word from its own parts instead of borrowing the
sound. Taxi is 出租车 (chūzūchē), roughly “rent-out car”, and tennis is 网球 (wǎngqiú), “net ball”. That
leaves 3 matches: pizza, taco and mango.
These counts cover single words and short phrases alike. Of the 430 phrases in the course, such
as “Nice to meet you”, almost none match, so if you only count single words the shares are a little higher
(Dutch: 22.8% of 1,778).
Where English is the odd one out
Sometimes most of Europe agrees and English goes its own way. Pineapple is ananas in 15
of the 22 languages, including German, French, Polish and Turkish. Movie is film in 15,
and billion is milliard or a close relative (Milliarde, miliardo, miljard) in 14.
False friends hiding in the list
The same letters can mean different things. Our script found 247 spellings that
appear in two languages for two different words in the course. Many are near misses, like French horloge
(clock) and Dutch horloge (watch). Some are real traps:

Serbian joins in, Chinese sits out
Take the 72 words that at least 15 languages share. Serbian has the shared form in
all 72 of them, more than any other language, including English
(69). Serbian spells words the way they sound, so a borrowed word like
saksofon or kajak keeps a form every other language can read. Romanian (70),
Italian and Swedish (69 each) follow. Chinese joins in 6 of the 72.
How we measured it
Every number here was computed from the Flashcardly course database on 26 September 2026 by one script,
which you can check against the downloadable results.
The words. All 2,208 concepts in our 184 lessons, each with one translation per language
chosen and reviewed for the course. That makes 510,048 language-pair comparisons.
Articles removed. “Der Apfel”, “la manzana” and “un măr” become Apfel, manzana and măr. We also drop
English “to” and Romanian “a” in front of verbs.
One alphabet. Russian, Greek, Arabic, Hebrew, Japanese, Korean and Chinese are compared through the
romanization stored with every course word (pinyin for Chinese, Hepburn for Japanese, Revised
Romanization for Korean). Serbian is taught in Latin script.
Normalised. Lowercase, accents and tone marks removed (é → e, ō → o, ǐ → i), spaces and punctuation
dropped.
Spelling folded. Different alphabets spell the same sound differently, so a short fixed list of
equivalences is applied to every language the same way: ph → f, th → t, c/k/q → k (c before e, i → s),
w → v, y → i, x → ks, z/ts/tz → s, and doubled letters count once. This is what lets pizza, pitsa and
piza line up.
Similarity. For each pair of translations of the same word, we compute how many letter edits turn
one into the other (the Levenshtein distance) and divide by the longer length. A score of
0.75 or higher counts as “the same or nearly the same”: at most one letter different in a
four-letter word, two in an eight-letter word. Only translations of the same concept are compared, so the
folding cannot match two unrelated words.
“Same in N languages”. For each word, we try every language’s version as the centre, count how many
languages fall within the threshold of it, and keep the largest group.
The cut-off is a choice, so here is how the main numbers move if you pick a different one:
The same counts at stricter and looser cut-offs. 1.0 means identical after normalising.

What this can’t tell you
It is our course, not the whole language. 2,208 words that beginners and intermediate
learners need is a useful sample, but a different word list would give different numbers.
One translation per word. Languages often have two words for a thing, and we only compare the one the
course teaches. For taxi that is Hebrew מונית (monit), so Hebrew counts as a miss.
Letters, not sounds. Romanization is a spelling system, and edit distance counts letters. Two words
can sound alike and score low, or look alike and sound different.
Similar is not the same as related. Most of the big matches are loanwords, but we make no claims
about where any individual word came from. Some short matches will be coincidence.

The full results as a CSV have one row per word (2,208 rows): the English word, its
lesson, how many languages share it and which ones, and for each of the 22 languages the course

Questions
Is there a word that is the same in every language?
Not letter for letter. In our study of 2,208 everyday words across 22 languages, no word is spelled identically in all 22. Pizza comes closest: it is recognisably the same in all 22 once other alphabets are written in Latin letters, including Chinese bǐsà and Korean pija. Taco follows in 21 languages, and yoga, cricket and kiwi in 20.
Which two languages share the most words?
In our data, Spanish and Portuguese, by a wide margin. 959 of the 2,208 words (43%) are the same or nearly the same in both. Next come Spanish and Italian (28%), German and Dutch (26%) and Italian and Portuguese (25%).
Which language is easiest to recognise for an English speaker?
By this measure, Dutch. 417 of the 2,208 course words (19%) look almost the same as the English word. Swedish (387) and French (365) follow. Chinese is at the other end with 3 words.
Why do so many languages share words like taxi, radio and pizza?
When a new thing spreads around the world, its name often travels with it and gets adapted to each language's spelling. That is why the most widely shared words in our list are foods, sports and technology rather than basic words like water or mother, which each language already had.
