How to read your way into a language with Lexico

21 October 2026

The short version: read a lot, guess before you tap, save a few words per chapter, and review them for five minutes a day. If you do that, you will need fewer taps with every chapter, and that falling number is your progress.

This guide explains why, using what language researchers have learned about how adults pick up a new language. Then it shows how to put each idea to work with the features already in Lexico. It is long on purpose. Read the sections that interest you and skip the rest; the first-week plan near the end works on its own.

Why reading works

You learn a language mostly by understanding a lot of it. Stephen Krashen made this argument in the 1980s, and decades of research on reading since then have backed the core of it. Every page you understand teaches you words and grammar you were never explicitly taught.

But adults are not children, and that matters in two ways.

Adults learn well from explanations. Children absorb grammar without noticing it. Adults rely much more on conscious learning: understanding why a verb has that ending, then meeting it again and again until it becomes automatic. The psychologist Zoltán Dörnyei describes this as a path from knowing a rule to using it without thinking. A reader with explanations on tap gets both halves of that path.

You already know a lot. French, Spanish, Italian and German use the same alphabet as English and share thousands of related words. The bilingualism researcher Ellen Bialystok showed that reading skills carry over between languages, most strongly when the writing systems are alike. You are not starting from zero. You bring your reading habits, your sense of story, and a large stock of words that look familiar.

It is not too late. Bialystok also argued against the idea of a sharp cut-off age for learning languages. Ability declines gradually, not suddenly, and adults can reach a high level, especially in reading.

One more idea runs through this guide. Research on bilinguals, summed up in Jeff MacSwan's collection Multilingual Perspectives on Translanguaging, treats the languages in your head as one connected system. Using English to understand French is not cheating. It is how a bilingual mind works.

Choose a book that fits

The right book is one you can mostly follow. Vocabulary researchers such as Paul Nation and Batia Laufer found that reading feels comfortable when you know roughly 95–98% of the words on the page. Below that, you spend more time looking things up than reading.

Lexico lowers that bar, because a tap fills the gap. Still, the principle holds: if you are tapping almost every sentence, the book is too hard for now.

Start short. Begin with one of the short stories in the free library, not a 600-page novel. A story you finish in a week teaches more than a novel you abandon on page 12. Finishing also tells you something useful: that you can.

Pick what you would read anyway. Motivation research, Dörnyei's in particular, keeps finding that people persist when they can picture the person they want to become. "Someone who reads Maupassant in French" is a stronger picture than "someone with a 40-day streak." Choose a book that belongs to that picture.

Rereading is allowed. A second pass through a short story is often faster and more pleasant than the first, because the words you learned are still fresh. It is one of the best ways to turn half-known words into known ones.

A rough test. Read the first page. If you understand the gist with fewer than half of the sentences tapped, it is a good fit. If you tap nearly everything and still feel lost, choose something shorter and come back later.

Read first, tap second

The single most useful habit: read the whole sentence, make a guess, then tap.

It sounds like a small thing. But research on how we learn language, summed up well in Caroline Rowland's Understanding Child Language Acquisition, points to prediction as a driver of learning. When you expect something and turn out to be wrong, the correction sticks. When you tap before you have thought at all, there is no expectation to correct. Memory research says the same thing from another angle: trying to recall or work something out, even when you fail, strengthens learning more than simply being told.

So, in practice:

Read the sentence to the end. Meaning often arrives with the last word, especially in German.
Say to yourself what you think it means, even roughly.
Tap the sentence. Compare the translation with your guess.
If one word made the difference, tap it to see its gloss.

Let some words go. You do not need every word. If you understood the sentence and the story is moving, keep reading. A word that matters will come back, and you will meet it again in a new sentence, which is exactly how words are learned. Rowland describes how meaning gets pinned down across many different situations, not from one look-up.

Tap freely when you need to. Guessing first is not a test. If a sentence is opaque, tap it straight away. Lost readers stop reading, and stopping is worse than tapping.

Use the explanations

When you tap a word, Lexico tells you what form it is in and why: fut is the passé simple of être; dijo is the preterite of decir. Read these. They are the fastest way to the kind of knowledge adults learn best from.

The linguist Richard Schmidt argued that we only learn the parts of a language we actually notice. You can read il était a hundred times without registering that it is a different tense from il fut. One explanation, at the right moment, makes you see it, and after that you notice it everywhere.

Hunt one pattern per chapter. Pick one form that keeps showing up and watch for it on purpose. In nineteenth-century French novels it is often the passé simple. In Don Quijote it may be the old forms of address. In German it is the verb that waits until the end of the clause. You are not memorising a table; you are training your eye.

See the pattern on different words. Rowland's research shows that learners generalise a pattern once they have seen it on many different words, not on the same word many times. When you meet parlava, mangiava and dormiva in the same chapter, take a second to see the shared ending. That is the moment a rule starts to work for you.

Do not study the grammar instead of reading. The explanation is a help for the sentence in front of you. Read it, understand the sentence, move on. The story is still the point.

Save fewer words, better

It is tempting to save every word you tap. Don't. A deck of 400 cards after one chapter turns review into a chore, and a chore is the first thing you skip.

A useful rule of thumb: save about five to ten words per chapter. Choose them like this.

Words you have tapped twice. The second look-up is the signal. The word is common enough to come back, and you have not caught it yet.
Words you would use yourself. Pourtant, sin embargo, eppure, trotzdem — the small words that hold sentences together pay off in every book you read afterwards.
Words that block the story. If not knowing it made you lose the thread, save it.

Skip the rest:

Rare and old words. A nineteenth-century name for a carriage part can stay in the nineteenth century.
Obvious relatives of English words. You will recognise magnifique without a card. More on this below.

Research on vocabulary suggests a word usually needs many encounters, often ten or more, before it is truly yours. A card provides some of those encounters; the book provides the rest. Saving fewer words leaves room for the book to do its share.

Review in short, spaced sessions

The words you save become flashcards that come back on a schedule: soon at first, then at longer and longer gaps. This is spaced repetition, and it rests on two of the most reliable findings in memory research. Reviews spread over days beat the same amount of study crammed into one sitting. And pulling an answer out of memory strengthens it far more than rereading it.

Five minutes, most days. Short and regular beats long and rare. Review before you start reading, while you wait for coffee, or from the widget.

Answer before you flip. Say the meaning to yourself first. If you flip straight away, you are rereading, not recalling.

Be honest with the buttons. Again is not a failure; it is information. Mark a card Again if you hesitated or got it partly wrong, Good if it came with a little effort, Easy only if it was instant. Generous grading feels nice today and costs you next week, because cards come back too late.

Remember the sentence, not just the word. Your cards come from real sentences in the book. When a word comes up, try to recall the scene it came from. Words remembered in context are easier to use and harder to forget.

Keep the pile small. If reviews start to take more than ten minutes, save fewer new words for a few days. The schedule will settle.

Your English is not cheating

Some methods tell you to banish your first language and think only in the new one. The research on bilinguals does not support that. The scholars in MacSwan's Multilingual Perspectives on Translanguaging disagree about a lot, but most of them agree that learners should be free to use everything they know. The late linguist Vivian Cook, who wrote one of its chapters, spent his career arguing that a second-language user is not a failed native speaker. You are building something new: a mind that holds two languages at once.

In practice, that means four things.

Use the translation without guilt. Tapping a sentence and reading it in English is how you turn a page you cannot read into a page you can learn from. As you improve, you will tap less. That is the right way for English to step back: gradually, because you need it less, not because you forbid it.

Lean on related words. English borrowed heavily from French and Latin, and shares old roots with German. Nécessaire, necesario, necessario and notwendig are not equally easy, and that is the point: you can see where your English helps and where it does not. Read related words fast, and save your effort for the ones that look nothing like English.

Watch for false friends. Some words look familiar and mean something else. Actuellement means currently, not actually. Embarazada means pregnant. In German, Gift means poison; in Italian, camera means room. When a sentence suddenly makes no sense, a false friend is often the reason. Tap it, and save it: these are some of the best words to put on a card.

Use your other languages too. If you already read French and are now reading Italian, let one help the other. Finestra is fenêtre; giorno is jour. Bialystok's research shows that knowledge transfers between similar languages, so your second Romance language should come faster than your first.

Build the habit in sentences

Languages are learned over months, so the habit matters more than any single session. Lexico's habit tools are built around reading, not minutes on a timer.

Set a goal in sentences. A daily goal of sentences read is concrete and fair: a hard page counts the same as an easy one, and you always know how far you are. Start low, around 30–50 sentences a day, a page or two. Raise it only when it feels easy for a full week. A goal you hit every day beats an ambitious one you miss.

Let the streak work for you, not the other way round. A streak is useful while it gets you to open the book. It becomes harmful when it makes you open the app, tap three sentences and leave. If that starts happening, lower your goal. Use the streak freeze on days you genuinely cannot read; missing one day does not undo anything.

Keep the book where you look. Put the widget on your home screen. It turns the moment you would open social media into a moment you might read one more sentence. Small cues like this do more for habits than willpower.

Read in the right light. Lexico has five reading themes, from Paper to Night. Use a dark theme in bed and a light one on the train. Reading is easier when the page is comfortable, and research on motivation finds that how learning feels day to day is one of the strongest reasons people keep going.

Read anywhere. Books and your flashcards work offline. Download the book before a flight or a commute through tunnels, and dead time becomes reading time.

Read a little aloud. Now and then, read a paragraph out loud. You will notice which words you cannot pronounce, and saying sentences helps them stay in memory. Nobody is grading you; that is one of the advantages of learning with a book instead of a classroom.

The reading loop

Put together, the habits above form one loop. You go round it many times a day, and each pass makes the next page a little easier.

Read the whole sentence to the end.
Guess what it means, even roughly.
Tap the sentence and compare the translation with your guess.
Read the explanation for the word that made the difference.
Save it only if you have tapped it twice or it blocked the story.
Review your cards for five minutes a day, answering before you flip.

The falling number of taps is the most honest measure of progress you have. Compare the first page of a book with the last, and you will see it.

A first week with Lexico

About 15 minutes a day. The aim of week one is not to learn many words; it is to finish a short story and find a rhythm you can keep.

Day	Read	Review	Try this
1	Pick a short story; read the first page	—	Set a sentence goal you can hit on a bad day. Add the widget.
2	One or two pages	First cards, 2–3 min	Guess before every tap. Notice how often you were close.
3	One or two pages	3–5 min	Read every verb-form explanation that comes up. Pick one pattern to watch.
4	One or two pages	3–5 min	Save only words you tap twice. Skip rare ones.
5	One or two pages	5 min	Look for related English words and one false friend.
6	One or two pages	5 min	Read one paragraph aloud.
7	Finish the story, or reread the first chapter	5 min	Compare: how many taps did the last page need, against the first?

After week one, keep the same shape and change only one thing at a time: a slightly higher goal, a longer book, or a new pattern to watch.
