Lingoverse now has six exercise types — and a tutor that picks the right one

For most of the past year, Lingoverse generated exercises in three formats: fill-in-the-blank, word order, and matching. They worked. They got the job done for vocabulary that needed quick recall.

But three formats only test three kinds of knowing.

Today we are shipping three more, plus a small change in how the AI tutor offers them: reading comprehension, grammar choice, and error correction. And when you ask for practice without naming a type, the tutor now hands you a picker instead of guessing.

This post walks through what each exercise type does, when it earns its place in your study routine, and how the tutor decides whether to pick one for you or ask.

Why six types, not one

There is a common assumption in vocabulary apps: more exercise types means more variety, which means more engagement. That is part of it. But it is not the main reason.

The real reason is that different exercises test different kinds of knowing.

Knowing that conscientious means "careful and thorough" is not the same as being able to drop it into a sentence about your colleague. Recognizing a word in a paragraph is not the same as producing it from memory. Spotting a grammar error in someone else's writing is not the same as choosing the right form when you write your own.

When you only have one kind of exercise, you only train one kind of recall. The fluency-shaped hole in the middle stays there.

Each of the six types below targets a specific skill. The point of having all of them in one workspace is that the tutor — or you — can match the exercise to the gap.

The six exercise types

1. Fill-in-the-blank

The classic. A sentence with a missing word, and you supply it.

Fill-in-the-blank exercise with translation hints under each sentence — Fig 2Fill-in-the-blank — productive recall inside a sentence frame.

Fill-in-the-blank tests productive recall — you have to pull the word out of memory, not just recognize it. Lingoverse generates 5 to 15 sentences per exercise, weighted toward words from your current page and conversation, then mixes in words from your wider vocabulary where they fit naturally.

Two specialised modes kick in automatically when the topic calls for it:

Collocations — blanks target the verb or adjective that pairs with a noun ("make a decision", "strong tea")
Phrasal verbs — blanks target either the verb or the particle of a phrasal verb ("give up", "look after")

Best for: building active recall around words you have already met.

2. Word order

You see a scrambled sentence. You arrange the words in the right order.

Word-order exercise mid-arrangement, words shown as draggable chips — Fig 3Word order — drag chips into the right syntactic order.

Word order works on the layer between vocabulary and grammar — syntax. You can know every word in a sentence and still place them wrong. This is the exercise that trains the intuition for where each word goes.

It is short on purpose: 3 to 5 sentences per session. The scrambled version always contains every word from the original — including articles — so the difficulty comes from arrangement, not from a missing piece.

Best for: catching word-order habits from your native language that quietly leak into your target language.

3. Matching

Two columns. Words on one side, definitions or translations on the other. Connect them.

Matching exercise — target-language terms on the left, native-language definitions on the right — Fig 4Matching — batch recognition across your saved vocabulary.

Matching is the most efficient way to test recognition across a batch of words at once. Lingoverse generates 5 to 8 pairs per session, drawn from your current page when possible, your wider vocabulary when not.

It is the right pick when you want to confirm that the meanings are sticking before you graduate to production exercises.

Best for: quick warm-ups, end-of-week reviews, or checking a batch of new words you just saved.

4. Reading comprehension — new

This is the one we are most proud of.

Reading comprehension exercise — passage with pastel highlights and a multiple-choice question — Fig 5Reading comprehension — your vocabulary doing real work in connected prose.

Most vocabulary apps stop at the level of individual words. Reading is what happens when you stop pulling words from a list and start meeting them in connected prose — the way you actually meet them in life.

Lingoverse generates a 150–250 word passage in your target language, naturally working in vocabulary from your page. Then it asks 3 to 5 multiple-choice comprehension questions in the same language. Key vocabulary in the passage is highlighted in stable pastel colors, so the words you are practicing visually anchor as you read.

When a topic benefits from outside context, Lingoverse can pull real-world facts from the web before writing the passage — useful when the topic is "octopus intelligence" or "the history of espresso" and you want the language to feel authentic rather than generic.

And the passage is not a dead end. If a highlighted word — or any unfamiliar word — catches your eye, send it to chat in one click, ask about it, and save it to your vocabulary. Reading becomes a source of the next words to practise, not just a test of the words you already saved.

Best for: bridging from word lists to actual reading. This is the exercise that proves your saved vocabulary is doing real work.

5. Grammar choice — new

A sentence with a gap, two options, pick the right one.

Grammar choice exercise — two options per sentence with native-language explanations — Fig 6Grammar choice — pick the right form, then read why.

Grammar choice is for the moments when vocabulary is not your problem, but the form is.

You know the word. You know the meaning. But should it be ser or estar? Por or para? Have been or had been? Grammar choice generates 5 to 12 sentences that test a specific rule, present two plausible options, and — critically — explain why the right one is right after you answer.

The wrong option is never obviously wrong. It is the kind of mistake a learner at your level would actually make.

Best for: locking down a specific grammar rule that keeps tripping you up. Ask for "grammar choice on ser vs estar" and that is what you get.

6. Error correction — new

A sentence with exactly one mistake. Find it, fix it.

Error correction exercise — find the mistake in each sentence and type the fix — Error correction before and after submitting — identify the mistake, type the fix, then read the rule.

Error correction exercise after answering — green/red feedback states with native-language explanations and an Explain Mistakes button — Error correction before and after submitting — identify the mistake, type the fix, then read the rule.

Error correction is the only exercise format that asks you to look at language critically rather than produce it from scratch. You scan a sentence the way a teacher would. You spot what is off. You name the fix.

Lingoverse generates 5 to 10 sentences, each with exactly one error: a wrong verb tense, wrong conjugation, gender or number agreement, wrong preposition, wrong word choice. Every item comes with an explanation in your native language of what the error is and why your correction is right.

Best for: training the editing instinct you need for your own writing. If you are preparing for a writing exam, this is the highest-leverage exercise of the six.

A picker, not a guess

The change to the chat tutor is smaller but it matters.

Before today, when you asked for "an exercise" without naming a type, the tutor picked one based on context and ran with it. Sometimes that worked. Often it picked fill-in-the-blank because it was the safest default, even when reading or grammar choice would have been a better fit for what you were doing.

Now, when you ask for practice without specifying a type, the tutor shows you the exercise type picker — an interactive card right in the chat, with all six options laid out as tiles. Pick one and the exercise generates immediately, carrying forward whatever topic or vocabulary you mentioned in the original request.

Exercise type picker after the user asks for 'an exercise on food vocabulary' — Fig 9Contextual picker — the tutor offers types that match your topic.

If you do know which type you want — "give me a reading exercise about coffee", "matching for my saved food words", "grammar choice for ser vs estar" — the tutor skips the picker and generates the exercise directly. The picker only shows up when you have not made the call yourself.

What this means for how you study

Three small shifts:

You can now match exercise to weakness, not just to availability. If you can recognize words but can't produce them, fill-in-the-blank. If recognition itself is shaky, matching. If your grammar is what's failing in writing, grammar choice and error correction. If you want to see your vocabulary do real work in connected text, reading.

The tutor is more honest about what it doesn't know. When you haven't specified a type, the picker is an acknowledgement that there is no single right default. You get to make the call.

The same vocabulary can drive five completely different sessions. A list of 15 words on a single page can become a matching warm-up, a fill-in-the-blank production drill, a reading passage built around them, a grammar-choice exercise testing a tense those words appear in, and an error-correction pass on common mistakes. That is the case for keeping vocabulary in one place instead of scattered across notes and apps.

What is next

The current six types cover the spectrum from recognition to production to editing. We are not planning to keep adding exercise formats for the sake of count — the next round of work is on the depth of each one (more reliable topic targeting on reading, smarter difficulty calibration on grammar choice, deeper integration with the flashcard review you already use on the page).

If you have a Lingoverse account, the exercise type picker is live in your chat right now. Open any page, ask for an exercise, see all six options.

If you are reading this and you don't have an account yet, that is the workflow: save your own words, then practice them six different ways.
