Most widely used languages, including Python, JavaScript, and Java, use familiar English keywords such as if, while, function, and return. Are there programming languages with keywords or syntax based on other spoken languages, or languages that avoid words altogether? How do programmers who don't speak English learn to read and write code?

No. English is dominant because programming ecosystems, documentation, and international collaboration developed around it, but there are programming languages with localized keywords in languages such as Portuguese or Spanish. They tend to remain niche because they have fewer libraries, tutorials, and users. Some languages, such as APL, rely heavily on specialized symbols instead of words, and graphical or experimental languages may avoid ordinary keywords almost entirely.
Not every language is really based on English at all. Assembly languages are textual names for the numeric instructions supported by a processor, and some systems use symbols or visual elements instead of words. Still, most mainstream tools use English identifiers and documentation because English functions as the common working language of international programming.
Localized versions can sometimes cause compatibility problems. If a language changes its keywords according to the user’s language or regional settings, code may stop working when moved to another system. That’s one reason English-based syntax is useful: the code remains consistent across countries, even when programmers’ spoken languages differ.
For someone who doesn’t speak English, the programming vocabulary usually isn’t a major obstacle. Courses and manuals can be translated, while keywords stay fixed as part of the language’s syntax. People learn words like return or while as technical labels, much like learning any other set of rules. Even translated programming courses often teach the same English keywords so students can work with the broader ecosystem.
Even small spelling differences can matter. For example, HTML uses color rather than the British spelling colour, so perfectly understandable English can still produce invalid code if the language expects a specific form.
