I wrote a book about LaTeX, and my proud grandma wanted to have a copy. So she got it, said "What a beautiful picture on the cover!" and - "What is this, LaTeX?".

She doesn't know Word, never used a computer. But she reads books. How can I explain what makes TeX and LaTeX special to a non-technical person? I don't mean introducing in using, and the existing question "What are TeX and LaTeX?" with its answers is still much too technical.

Such challenges are not rare. I need to explain to my boss why I request some days off to go to a TeX conference, and soon my daughter will want to know what daddy does on the computer. My girlfriend needs to understand why I spend so much time at TeX.SE.

Does anyone know eye-opening words? Perhaps an analogy or a metaphor would help? So grandma, girlfriend, daughter, boss - all may roughly understand and say "Ah, such a thing? Useful indeed!"

Hypothetical dialogue follows.

Dear <insert subject name here>,

I would like to spend a few minutes talking about something cool. In fact, it's not just cool. It's amazingly cool. It's not "Albert Einstein playing guitar" cool, neither "Abraham Lincoln riding a bear with a machine gun" cool, it's way more superb. Believe me, it's super duper ultra mega hyper kamehameha über cool. I'll talk about something called LaTeX.

googling latex is tragic.

No <insert subject name here>, it's not latex, but LaTeX. See the awesomeness right there? You have a completely different word, with caps and stuff. A word that you need to hold Shift no less than three times in order to get it right has to be good. Let's start with the basics.

Say lay.

Now, say techhhhhhh. The sound cannot come from the heart, it has to come from the throat. Some vocal exercises might help.

Good, now let's say those two words together: laytech. Good! Now you know how to pronounce this mysterious word. Please, clean up your monitor before proceeding (Don Knuth says monitors can get a little moist after such exercise). Who's Don, you say? Good ol' Donald Knuth, our guide! Here's a picture of him if you "don know don"! Ha! I'm funny.


No, Don doesn't have a TeX.sx T-shirt. Yet

Back to the LaTeX awesomeness. Do you like using Word, Writer or <insert word application name here>? Have you ever encountered some sort of problem when using any of them? I did. File formats, images out of their original place, bad formatting. To name a few. Anyway, these programs are great. But what if I tell you there's something even greater than all of these programs?


Yes, there is.

Think of a program that takes a bunch of text, plain text with some markup in it, enters inside a blackbox and voilà, a cool PDF magically appears in the other side! What's this markup thing?

Think of rules. Logical rules. Too fast? OK, let's start with some concepts. For example, let's say every time you want to write a text in boldface, instead of clicking the B button of your word application while selecting the text you want to apply this style, you will simply write this word before the text: QUACK. Wow, that's it? So

This is QUACK my text, yay!

will appear in bold?!

Yes. Of course, we need to define a range, so let's use another word to specify the end of the boldface range: POTATOES. Now,

This is QUACK my text, POTATOES yay!

Believe it or not, this is a markup rule! Awesome, isn't it?

In LaTeX, we replace QUACK by \textbf{ and POTATOES by }, but let's not worry with this now.

So, where should we type our texts? In any text editor! Yes, any editor. You just need to specify, via logical rules, how your document should look like. And guess what, LaTeX does the rest for you!

LaTeX is an application and it's free. Do you know what that means? You can get a high quality document and save money for beer!


LaTeX is shipped in something we call TeX distribution. Think of a toolbox. Everything you'll need is there. Just use and abuse.

We have something we call packages which help us make our documents look cooler. They are like LEGO blocks, just get the one you need for your project and use it!

So you see, <insert subject name here>, we can use LaTeX in virtually any kind of document! Think of newspapers, articles, books, calendars, children party invitations, CVs, songsheets. The list is endless!

LaTeX generates beautiful documents from plain text. Simple yet amazing concepts. Why do I use it instead of a normal word application? LaTeX works.


Writing a document in LaTeX is similar of baking a pie. You have the ingredients, you know the order and how to dispose them. Now simply arrange them accordingly, put the plate into the oven and hope for the best. A document follows the same logic, sadly it's not as delicious as a pie.

Speaking of food, LaTeX is much like Marmite. Either you love or hate it.


Well, that's it, <insert subject name here>. Thanks for the pair of socks for my birthday, I really appreciate the thought. :)

    LaTeX to me is... NEVER HAVING TO USE A MOUSE... ever. Commented Jan 24, 2013 at 17:44

If people ask me what LaTeX is, I explain it like this:

Imagine you wrote a book and want to publish it. You, as an author, are good at writing and explaining stuff but you don't know how to "design" it.

When your book looks like this, you wouldn't earn a penny, selling it:

plain Text

What you need is someone who is trained at making text readable and looking beautiful at the same time. This guy is called lector. He creates a concept of your book. For him it is enough to know what kind of book you are writing, but he does not need to know what is in it.

After his work is done the concept could look like this:

concept document

Now that we have a concept, we need to combine both parts together. The one who gets paid for this is called the typesetter. She takes both parts and puts them together.

The result could look like this:

typeset document

We've learned that it takes 3 people to create a book, the author, the lector and the typesetter. But what has this got to do with LaTeX? This is a pretty easy question. We are the author and LaTeX does the job of the lector and the typesetter. It creates a concept and combines it with the text we have written. We don't have to spend time thinking about how it should look like because LaTeX will find the best way and make it look great.

(About "Russischer Zupfkuchen" see e.g. here. It is some sort of cheesecake)

A dubious analogy?... guess we'll see

Imagine that you are baking a cake, and that somehow you could magically get software on a computer to do it for you.

LaTeX would...

  • measure the ingredients
  • mix them perfectly
  • create very little mess
  • write down all of its decisions for you to follow later
  • would only ever ask you for clarification if it was absolutely necessary
  • bake the cake and produce among the best tasting cake you have ever eaten

Other software would....

  • probably not do it nearly as well, and you'd end up having to make the cake yourself

Once the analogy has been made, replace 'baking a cake' for 'typesetting a document', 'ingredients' for 'content', and 'best tasting cake you have ever eaten' for 'best looking document you have ever seen'.

Of course, the user has to provide the ingredients/content :)


It is useless to explain some thing to some people. Your explanations will be too complicated or too boring.

Probably is better to explain first what is NOT LaTeX to keep you out of trouble when people look in Google to see where you spend your time. I've seen that Paulo Cereda also thought about this risks. In a second step you can explain that playing with \Latex is a type of serious work (I had thought just in the same image already uploaded by David Carlisle for this). Also it is worth to mention that you are not a slave of a strange glambling addiction. For thus I think in some examples of that anyone can learn just here ... but may be this is not a good idea.


I simply would say LaTeX is the way to produce beautiful texts that even you, dear grandma, who never typed an e-mail, can appreciate it.

Explaining technical tools to those with less technological context is often hard. Things they're most interested in tend to be who might use it and why that person might use it, as opposed to technical details.

  • What is LaTeX? LaTeX is a programming language for writing, most often for technical writing.
  • What problem does LaTeX solve? The problem is that there is a lot of useful technical jargon that doesn't get formatted well in paragraphs, such as formulas and graphs. LaTeX is often used to take that content that is hard to format, and lay it out in a visually appealing way.
  • Who uses it? Many writers use LaTeX, but especially technical writers who need to write out those mathematical or scientific symbols, graphs, notations, and other content that's harder to get or use in simpler word processors.

In a short paragraph, that might read as:

LaTeX is a programming language that a writer uses to get the computer to understand complicated ideas about how to lay out a document. It was designed for technical documents, with lots of support for math and science notation, so it's most often used by technical writers to help visually organize their material. A paper written in LaTeX is often pretty and well designed with much less effort than plain text.

That's a problem I bumped into several times (I used to work on projects in which the aim was to produce e-learning material about the internet for seniors, who never used a PC - go figure...).

In such cases I try to explain by starting with an analogy taking an example from - well, you know it - the analog world. :) In the case of LaTeX I would focus on typesetting. It existed way before computers and should be pretty easy to understand as a concept. Then I'd sum up in a few words the motivation of the venerable master Knuth to typeset beautiful papers, mainly because of the botched way math was typeset back then (in the early days so to say) - because for cost reduction typewriters were used to do this - to finally jump to present day and oversimplify a bit by selling the computer as a very smart typewriter.

That's it roughly. Add details/anecdotes as required.

... and don't forget to mention your book was typeset with LaTeX! :)

    but math used to be "beautiful" -- knuth followed the principles of the compositors who produced books and journals with metal type. it's only when typewriters (albeit super-functional ones) started being used (to reduce costs) and then computers were enlisted to make the decisions without human intervention that the quality went downhill. addison-wesley would never have used typewriter composition for a knuth book, but by the time a second edition of vol.2 was needed, there were no human compositors left to set metal type.

Your oven = My computer

Your recipe = My code

Your mixer machine = My TeX engine

Your delicious cake = My beautiful book


I would explain like so:

Remember the old printing presses? They would have some typesetters putting all the letters in place on the press. The typesetters would work according to rules about which font should be used where, how things should line up, where the pictures should go, what the margins would be, how the pages should be numbered and so on.

LaTeX is some computing software from making electronic documents. However, unlike using a word processor, people who use LaTeX are like modern typesetters. With LaTeX they can create rules about fonts, margins, colours, pictures, layout and so on, and then the document they are making will come out accordingly. What's even better is they can put these rules into a special file to share them with people. Then those peoples' documents will come out with the same formatting and style. This makes things really easy as none has to worry about formatting and can get on with writing.

All this control means that documents made with LaTeX look beautiful with little effort. The quality of LaTeX compared to a word processor can be like the quality of a newspaper compared to typewriter.


I would order one of the (oh so many) self-edited books on Lulu or Amazon made with Microsoft Word, with page numbers inside the bindings, no justification, no hyphenation, no indexes, etc. and show her the difference: with LaTeX, this wouldn't have happened…


LaTeX is a language that a human being can use to let a computer know how a manuscript should be typeset and printed.


LaTeX is a bunch of superfluous abstractions built on top of the TeX typesetting language. A typesetting language which computationally imitates the work of a typesetter.

I think I would show what TeX can do. I think people are underestimating grandma. It doesn't take technical nous to appreciate beauty or clarity.

This leaflet was designed to advertise and explain TeX. It contains a mix of different things so might be nice to show a family group, for example, with lots of different interests. Karl Berry notes that you need to zoom in to really appreciate it - it looks much less impressive until you start examining the detail and it is packed with detail.

The TeX Showcase is excellent in part because you can select examples of particular interest to particular people. For example, your grandma might like this book sample or this more scientific one. If your grandma is from my part of the world The Book of Tea might go down especially well. Or perhaps this genealogy if grandma is interested in family history.

While not the best choice for somebody who doesn't use computers, there are plenty of suitable examples there with a more hi-tech feel as well. And linguists should have a field day, too.

  • @tohecz I doubt it uses the entire LaTeX system, probably just the math typesetting aspect (and possibly some other environments). It doesn't use mathjax but some hash-based renderer (which is rather irritating when you want to look up how an equation was typed up)

    as long as they do not use the Knuths math formula algorithm, I'm unwilling to call it (*)TeX.

This is very grandma-specific:

LaTeX is for writing good-looking books what knitting is for making a warm pair of socks.


Latex is a tool for

changing atoms into characters,

molecules into words,

planets & stars into sentences,

solar systems into paragraphs,

galaxies into chapters ...

the Universe into text.

  • I think the implications of this analogy is a valid definition for a run-on sentence :) Commented Jun 5, 2015 at 17:09
  • @SeanAllred I'm not that good with english. Does it mean that it is grammaticaly incorrect or written with poor style?

  • Oh, no -- your English is fine :) The implication is that planets/starts are made of many molecules: sentences with similar proportions of words would be... untenable. :) Just a quirky observation. Commented Jun 5, 2015 at 19:51
  • I got it -- maybe all this is just stardust. :)

This is hard. To most grandmas a computer is a magic and/or useless box which for some reason the younger generations can't get enough of. To most grandmas, a computer is indeed that big white box with a "tv" attached or next to it; the inner workings mean nothing to them (they wouldn't refer to a smartphone as a "computer", and perhaps not even a "phone" unless they see it being used as such... might as well be a remote). I know, some of your grandmas probably use facebook, have smartphones and whatnot, but that's not the case here or in general.

That being said, I think that the most reasonable way to exaplain it is to say "it's a way of making books look as nice as they do", and then you show her a printed book as an example, and point out certain details and how nice the book is because of it.


I guess you could say that LaTeX is like a typewriter that doesn't print your words right away—it remembers them instead. Then at the end, when your document is done and you want to print it out on paper, LaTeX asks you how you want it to look. You say "like a nice looking book", and it prints out your words as a nice looking book, without you having to work hard to make it look like that.

But maybe you change your mind, and say "I like the way the New York Times looks, make it look more like that". So LaTeX prints out your words again and they look like the New York Times, and once again, you didn't have to work hard to make it look different because LaTeX did that for you. It's like a typewriter with a brain.

The example might be a bit simplistic, but the separation of content from the layout is probably one of the easier things to understand about LaTeX.
