Swap the en for simple in the web address

You look something up — a diagnosis somebody said quickly, a term in a letter, a word your colleagues use as though it were obvious — and the encyclopedia entry turns out to be harder than the thing you were trying to understand. You read the first paragraph twice. Then you close it.

The conclusion people tend to draw at that point is about themselves, and it is worth knowing how often it is the wrong one.

Wikipedia has a second edition written in about a thousand common words, and you reach it by changing the en at the front of the web address to simple.

That is all of it. en.wikipedia.org/wiki/Photosynthesis becomes simple.wikipedia.org/wiki/Photosynthesis, and you get an article that opens by telling you plants make their own food from sunlight. The same switch is available from the language list on the page, where it is filed as “Simple English” alongside the actual other languages.

Why the first article was hard

Not because it was bad. Because of who wrote it and who they were picturing.

The technical parts of Wikipedia are largely written by people who know those subjects properly, which is why they are accurate, and it is also why they are often impenetrable — an expert writing carefully for other experts produces something correct and unreadable at the same time. Somebody in these conversations made the related point about asking for a plain explanation anywhere: the clear answer tends to get buried under people who would rather be precise than be understood.

So the difficulty was a property of the document. It was written for somebody else. There is a version written for you, and it is not a consolation prize — it is a different translation of the same thing.

Who it was actually built for

This is the part worth knowing, because people assume the simple version is for children and feel faintly ridiculous using it.

The project’s own statement of purpose names four groups: students, children, adults with learning difficulties, and people who are trying to learn English. It began mainly as a resource for the last of those — an encyclopedia readable by someone whose English is their second or fourth language — and native speakers arriving at it for other reasons were a later and entirely welcome development.

Which means that if you are reading in a second language, or you are tired, or you are on medication that has taken the edge off your concentration, or reading has always been hard work for you, you are not sneaking in. You are the intended reader, and it says so.

The plainness is not an accident of tone either. Contributors write from a restricted word list — Ogden’s Basic English, about eight hundred and fifty words, stretched to roughly fifteen hundred with international terms and the vocabulary of trade and science. That constraint is the whole method.

Where it will not be there

Now the limits, and one of them is genuinely annoying.

Only a fraction of Wikipedia has a simple version. At the end of August 2026 it was around two hundred and eighty thousand articles against more than seven million, which is roughly one in twenty-five. Somebody argued that the covered fraction probably carries most of the actual reading, since traffic concentrates on well-known topics, and that sounds right without being something anybody here demonstrated.

The annoying part is the shape of the gap. The articles hard enough to need simplifying are the ones least likely to have been simplified, because rewriting them is difficult and thankless. On one subject the simple page reportedly says outright that the idea cannot be put in simple terms. One person’s impression was that science and maths topics are better covered than the rest.

And it is a separate encyclopedia rather than a filter applied to the main one. No button gets pressed; a person rewrites the article, the way a person translates it into Portuguese. So the two pages can drift apart, and neither is a summary of the other.

When it is the wrong tool

If you need depth — a course to pass, a subject to actually learn, a citation for a piece of work — this will not carry you, and using it as a source is not a thing you can do. Several people were blunt about that: for calculus revision the simple page is not thin, it is absent where it counts.

Its job is to get you standing up. Read the plain version until the shape of the thing is clear, then go back to the full article, which will have stopped being a wall.

There is one more route worth having, offered by somebody almost in passing. Switch the article to another language you read, or one you can run through a translator, and you often get a different piece of writing altogether — different emphasis, different examples, occasionally material that was never in the English one. Encyclopedias are not one book translated. They are many books, and you are allowed to go and find the one that talks to you.
