Feature

The meaning it has in this sentence, not five dictionary senses

Clicking a word opens the same card everywhere in NoaLingua. Beyond the dictionary entry it works out which meaning fits this particular sentence, identifies the exact inflected form you clicked, opens the conjugation table at that tense, and shows real bilingual examples — and it omits the contextual line rather than inventing one.

  1. Caption blocks are reassembled into sentences before anything is translated — one YouTube caption block is usually not a sentence. The dotted underline marks a statistically uncommon word; faded words are ones you marked known.
  2. “In this sentence” is the line a dictionary cannot give you. It is chosen from the sentence translation, the word’s translation list, the part of speech and the preceding word — and when the evidence is weak it does not appear at all, rather than being invented.
  3. Every button is also a key, and each tooltip shows your current binding. R repeats the sentence you can see, not the one the player has already moved on to.
The word popup open over a paused video: the clicked word empfahl with its meaning in that sentence, its grammar, the full conjugation table opened at the tense clicked, and real example sentences with audio.
One click, one popup: the meaning in this sentence, the grammar, every tense, and examples you can hear — without leaving the video.

How to use it

Step by step

  1. 1

    Click a word — in a subtitle, on a page, or in a PDF

    It is the same card from every surface, with the same data and the same Save button.

  2. 2

    Read the “in this sentence” line first

    That is the sense the word carries here, chosen from the sentence translation, the word’s translation list, the part of speech and the word immediately before it.

  3. 3

    Open the grammar row for the form you clicked

    It names the exact form — “3rd person singular present of faire” — and opens the full conjugation or declension table at that tense.

  4. 4

    Press Save, or I know it

    Save keeps the word with its sentence, the sentence translation, the source title and the exact timestamp. I know it saves it and marks it known in one action, so it stays searchable without appearing in sessions.

Mechanism

Why it behaves this way

How “in this sentence” is decided

A word with five dictionary senses has one sense here. Finding it is the difference between a dictionary and a tutor, and NoaLingua does it by combining four things it already has: the translation of the whole sentence, the list of translations for the word alone, the part of speech the grammar data reports, and the word immediately preceding.

When those do not converge, the line does not appear. It is never filled with the most common sense as a fallback, because a confident wrong meaning is worse than an absent one — you would learn it and not know to check.

Why a verb takes a moment longer than a noun

For an inflected form the extension has to resolve which base word the form belongs to before it can look anything up. With the Wiktionary pack downloaded that is a disk read; without it, it is a network round trip.

French and Italian elisions are stripped automatically first, so clicking l’arbitrage looks up arbitrage rather than failing.

Saving is instant, and the card fills in behind you

Save writes the card immediately — sentence, translation, source, timestamp — without waiting for any lookup to finish. Everything else arrives afterwards, through three separate safety nets: retries in the moments after saving, a sweep when a language pack finishes downloading, and a final attempt at review time when a human is reading the card and there is no deadline.

The alternative — blocking the save until every lookup returns — would mean losing the word every time a network call was slow, which is exactly when you are most likely to be watching something.

Where the data comes from, in order

Seven sources, cheapest first: UniMorph for morphology, the Wiktionary/kaikki pack for definitions and IPA, FreeDict/WikDict for the word’s own translation, and the Tatoeba corpus for examples — all from disk. Only if those cannot answer does it go to the Wiktionary API, Wikidata Lexeme or the Tatoeba API.

Those three network sources sit behind a single setting, and they receive the word alone. The sentence is never sent, and neither is any subtitle text.

Limitations

Common questions

Can I look up a phrase rather than a single word?

Yes — drag across two or more words in the original line and release. A collocation cannot be understood word by word, because the meaning is in none of them individually.

What happens to set expressions?

If the word you save belongs to a fixed expression such as en fait or avoir lieu, the expression gets its own card alongside the word, with the same sentence and timestamp. Both, not instead: the word is what you clicked, the expression is what is actually being learned.

Is there audio?

Every card has a pronounce button using the browser voice, slightly slowed. Where the sentence was captured from a video with a known end point, the card also carries the speaker’s real audio, and a review game later plays that rather than a synthetic voice.

Does hovering do anything?

Holding the mouse over a word for a moment shows a small bubble with up to three meanings from the offline dictionary. Nothing opens and nothing needs closing. It can be turned off.
