I learned to code before I learned proper English as a child.
However, many educators insist of forcing students to first learn Hungarian pseudocode (not Hungarian notation) stuff first, I specifically was forced to learn Hungarian pseudocode SQL, because our teacher thought the future of programming will be natural language programming (she was a mediocre mathematician). Problems with it include:
- Hungarian is very antithetical to be used as keywords in a programming language, mainly by substituting affixes with different words, or keeping the affixes in certain ways.
- Students who already know English or actual coding are confused by it.
- Natural language programming is quite bad. Nothing is gained by throwing out programming symbols in favor of natural language. In fact, things are being lost, and the main advocates of NLP are just out-of-touch techbros, who think creation is about having a cool idea.
- Time that could been spent learning other things are wasted on it.
I have no clue but at the very least, a programmer names their own variables and, barring any special characters, they could be named in any language.
much easier to look for guidance for coding in english instead of my native language, syntax makes more sense too. Though personally i would wish more stuff was properly translated into finnish instead of english slowly gnawing at it.
That’s probably fair, but I would also worry that anything coded in Finnish would be trying to find a way to kill me for not respecting its personal space.
Never even heard of a programming language in Danish. Even the ones invented by danes are in english.
I wrote variable names and comments in Spanish when I started as my English level back then was very low.
Once my English improved and started to use English documentation and tutorials I just switched to write in English.
In my previous job I worked at software consultancy, I had coworkers who wrote code in Spanish but it wasn’t the norm.
Currently I work for an international company, the team is Spanish but we have to write everything in English as it can be shared with teams in other countries and audited by international organisations.
When AI tools were allowed, a lot of people use them in Spanish, it generates code with comments in Spanish. I had to reject a lot of PRs from the same guys over an over because everything must be in English.
I use British English in variables for the word “colour”. It’s actually kind of useful because I can tell when it’s my own variable and when I’m interacting with something else.
Coding is all done in the language of the code… if, and, or, for, include, except, etc. It’s not exactly a vast array of words you need to know to be able to code.
Also, I can only speak for Sweden, but I started learning english in third grade. These days they start in kindergarten. Basic stuff, days of the week, 1 through 10. But still.
Are you coding in basic? Look at the std libs for any modern language and there is a plethora of words to learn to program effectively.
The words you need to “know” to code, compared to what you need to know to communicate effectively, are but a promille.
He also specifically said “learn to code”. Beginners often struggle with the concept of a loop, let alone trying to import a bunch of libraries
Russian here.
For the most part, it’s all English. Not even romanized Russian in variable names, although that happens sometimes. Comments are mostly in Russian, though. Depending on the company and whether it has to deal with countries where Russian isn’t as widespread (e: which is not a lot of companies these days), that English can be a little difficult to understand once you start applying English language logic to it as opposed to basically writing Russian poorly translated to English. It’s fine if the variables, classes and method names are short and offer little room for stringing words together, but anything complex poses risk of producing something that will be difficult to read without heavy Russian background and developed English skills (at both comprehending and producing).
However, there is a number of Russian-based programming language. I am fortunate to have never worked with any one of them. One of them is 1C:Enterprise, which is also a sizeable business for automation software and such.
Here’s what it looks like. I can spot a couple of English words there, though. And having learned programming through English and English only, I actually find it more difficult to read, because Russian-native developers still often refer to things in English, even if there’s a word for that same thing in Russian - it’s just that much part of your programming work.
That’s so trippy
Well we learn to code in the programming language that the teacher choses, not in any natural language at all, so neither English nor our native languages.
But all significant programming languages that I know do have reserved control words that are taken from English. Maybe that is the direction of your question?
Then no, mostly we don’t use specifically crafted or preprocessed programming languages just to have control words recognizable as words in our native languages. We just learn the English-based control words as features of the programming language, if we don’t already recognize them.
As for the variable names and natural language comments embedded in the code, that we create, that varies. I’d say as soon as interlingual collaboration or code sharing is a possibility, people will go for English in my experience. And I suspect that people who have gone for English before tend to stick to English even in their private use.
This is also related to learning materials, documentation of language features and libraries being available to the largest degree in English.
I perceive it as easier to stick to English, rather than to code switch between natural language while I program.
We always code in English at work. Using our native language for programming is generally frowned upon.
No chance, hungarian has non-ascii characters(ő and ű), digraphs(cs, dz, gy, ly, ny, sz, ty, zs) and a trigraph(dzs). Also generally how the language works is pretty disadvantegous to coding and tech. English has maaaany useful one syllable imperatives(get, click, etc), even with doors irl its often in english whether you pull or push cause hungarian doesnt really have these completely stateless verbs. One thing that did exist back in the day was people coding in german but i only know a single person who still does this.
There have been some interesting attempts to translate languages, but generally at most you would get phoneatically local names using English characters for functions and variables, etc.
Only in the very beginning people use anything besides english
I’m a native Spanish speaker, it depends on the language and the person.
Spanish has very few diacritics, so it’s quite understandable in ASCII (áéíóúüñ). But I guess it would be a lot harder in other languages like Czech or Vietnamese.
When I program for myself or in public repos, I tend to code everything in English, but when I have to do projects with classmates at my university, I usually do it in Spanish because they are not great at English.
Many programming languages support Unicode nowadays
Preferably in English. Nothing is worse than reading code with a mixture of languages. Although false friends can also be quite annoying.
They are annoying even if you write in English. One such example is “library”.
In Spanish, there are two words: “biblioteca” and “librería”.
Library = biblioteca
Book shop = librería
When speaking about programming libraries, everyone says “librería” because it’s just easier to translate that way. But it just feels wrong every time.
A funny one is Pizza Hut. “Hut” means “hat” in German. And since the Pizza Hut logo kind of looks like a hat many Germans believe that they gave it a German name in Germany. So they pronounce it in a German way and if they were to talk to an English speaker they might say Pizza Hat in an effort to translate.
Considering that their roofs tend to look like this, that’s a very reasonable understanding. Pizza Huts look like they’re wearing a hat!

Although false friends can also be quite annoying.
What does “false friends” mean?
As others stated, it is when two words in different languages are similar phonetically/graphically.
They are called false friends because they seem familiar and you expect to mean the same as with other words that are pronounced similarly in two languages and mean the same. False friends not just mean different things but they sometimes can change the phrase in a bad way.
Note: The following examples are with Spanish from Spain, they might be different in other Spanish speaking countries.
Alice and Bob discussed about having children
Alicia y Bob discutieron sobre tener niñosIn English Alice and Bob had a conversation, in Spanish they had an argument.
Bob is a sensible guy
Bob es un tipo sensibleBob is a person who acts with prudence and thinks carefully in English, in Spanish he is a guy who is easily affected by feelings.
I had an English teacher who told the same anecdote about false friends and her sister. She was in UK and the batteries for the remote died, so she went to a convenience store and asked if they had them.
The thing is that in Spanish we only use battery (batería) for the ones that are not meant to be replaced regularly, like the car battery, the laptop battery, etc. The replaceable ones (even the rechargeable that take the same shape), are called pilas. So in the anecdote, the sister told the woman at the store very confidently “Do you have piles?” (haemorrhoids, for the ones who doesn’t know).
I don’t know how real the anecdote was, but it fulfilled its purpose to make us aware of these situations.
In a nutshell, words that look the same / similar but with different meanings in their respective languages, making it pretty confusing.
Like homonyms or something different?
There are many false friends between French and English. Off the top of my head:
- EN: eventually (FR: un jour)
- FR: éventuellement (EN: possibly)
- EN: actually (FR: en fait)
- FR: actuellement (EN: currently)
“Enregistrer” in French both means to record or register something and to save a file, but you can’t use the English word “register” for both.
“Défense” in French both means defense and prohibited, but you can’t use the English “defense” for both.
False friends usually aren’t homonyms since the word comes from different languages.
To give an example: an English speaker might look at “rare auto” (Dutch) and might translate it to “rare car”. But “rare” means “weird” in Dutch. So rare is a false friend in this case
Edit: an example of a false friend that is a homonym is “horloge” in French and Dutch. They are pronounced and written the same, but it means “clock” in French but “(wrist)watch” in Dutch
Edit 2: just a writing mistake :)
The Dutch word for “who” - wie - is the same as as the German word for “how”.
Nastiest false friend I know because it’s a very common use word in both.
The more you know! German as a Dutch speaker has always been a bit of a special language (I’m assuming the other way around as well).Like some words are similar (like gevonden/gefunden). Which makes sense, but then some German composite words sound funny. Because we do understand what a bahn (baan) and hof (also hof) mean. But we call a bahnhof a station.
I first learned Dutch as a non-native speaker (I’m Portuguese and lived in The Netherlands for almost a decade) and only after that did I start learning German, and knowing Dutch is both helpful for it (due to things live verb order in the sentence and many, many words being very similar) but also problematic because of the false friends and also because whilst speaking one language words from the other often pop-up instead.
I’ve picked up Spanish because of speaking Portuguese as my native language, but unlike with that language pair were I always know for sure if a word is on one language or the other (probably because Portuguese is my native language), with the Dutch - German language pair that’s not at all the case and they seem to interfere with each other a lot in my mind.
Even though I learned Dutch first and to a much higher level, I don’t really get a feeling of strangeness with German probably because they’re both strange to me.
That said, I do get that strangeness with Spanish, were there are also some weird unexpected things vs Portuguese (like going along a sentence which is pretty much the same thing with a different accent but there’s a single word that’s totally different), though not in composite words since neither language has that.
That’s cool about “rare” in Dutch. It’s the same in Spanish. “Qué raro” means “How weird.” So that’s a false friend for English, but an accurate one between Spanish and Dutch!
Damn that’s cool!
Words in two different languages that sound the same but don’t habe the same meaning. Real example from my last work: The German word for “topic” is “Thema”. So our programmers called the database field and variables “theme”.
What should you do if you inherit a project where they are already mixing languages because they just copy pasted from tutorials?
Exacerbate the problem by using your own style that’s not been used before.
It’s tradition!
The only solution to having too many standards is always to add another new standard. /xkcd
TBF, USB C is an example of that approach actually working.
int main(){ cout << "It's more compact this way and yeah I'll die on this hill"; Return 0;} //see you even get to end lines in devious winky smilies who doesn't love that
The only things that tend to be in another language in code are variables and strings, from my experience.
