The Short Answer

In LingoUnify, saving a word is not one generic action. You are choosing a status.

Learning means "I want this word to stay visible." It belongs in the yellow or warm highlight state. Use it for words you want to notice again, translate quickly, review, or collect because they keep showing up.

Learned means "I already know this well enough." It belongs in the green highlight state. Use it for words you have met several times and can understand quickly in a fresh sentence.

That changes the usual advice. You can save more Learning words in LingoUnify than you would put into a traditional flashcard deck, because Learning also powers lookup, overlay highlighting, and word awareness while you read. Still, do not save every unknown word forever. The goal is to make future reading clearer, not to create a junk drawer.

The Color Key: Learning and Learned

The simplest way to think about saved words is as a reading map.

  • Learning, yellow or warm highlight: I want help noticing this word. I may need the translation, the context, or future review.
  • Learned, green highlight: I know this word well enough that I want it marked as known when it appears again.

The color is not decoration. It tells you what kind of attention the word needs. Yellow means "slow down if needed." Green means "keep moving, this is already yours."

A word can start as Learning after one lookup, become Learned after repeated exposure, move back to Learning if you were guessing, or be removed if it turns into noise.

Why This Is Different From a Normal Word List

Most vocabulary advice assumes that saving a word means adding another flashcard. In that system, saving too much is a real problem. A long list becomes review debt.

In LingoUnify, Learning can be lighter than that. A Learning word can be something you want the overlay to catch for you. If the word appears again, the highlight reminds you that you have seen it before. If a translation is available, the overlay can help you check it quickly. If the word no longer matters, you can remove it.

That does not mean you should mark every unknown word. Reading still needs flow. Richard Day and Julian Bamford's principles for extensive reading argue that learners should often keep reading instead of stopping for every unknown word, because fluent reading depends on tolerating some ambiguity.

Use Learning generously, but not mindlessly. The best saved words are still words that help future you.

Five Good Reasons to Save a Word as Learning

A word only needs one good reason to enter Learning.

  1. It blocks the sentence: Save it if the sentence does not make sense without it. If you can still follow the message, you may not need to stop.
  2. It keeps coming back: Save it if you have noticed it more than once this week. Repetition is a clue that the word belongs in your active zone.
  3. It is useful in your life: Save it if it helps you talk about work, family, travel, health, emotions, food, hobbies, or plans.
  4. It belongs to a phrase: Save the phrase if the meaning depends on the surrounding words. In French, avoir envie de is more useful than envie alone if the phrase is what you need.
  5. It helps separate meanings: Save words that clarify a contrast, such as savoir and connaître, apporter and emmener, or formal and informal ways to say "you."

The best Learning words are not always difficult words. They are words you want the app to keep catching for you.

A Worked Example

Imagine you are an A2 French learner and you read this sentence:

Marta est restée chez elle parce qu'elle était enrhumée, mais elle devait rendre un rapport demain.

A quick translation is:

Marta stayed at home because she had a cold, but she had to hand in a report tomorrow.

You might notice est restée chez elle, enrhumée, devait, rendre un rapport, and demain.

Save est restée chez elle if rester chez soi is still new. The phrase is common and useful, and seeing it highlighted again will help you notice the pattern.

Save devait if obligation still takes effort. Devoir appears constantly, so it is a strong candidate.

Save enrhumée if health vocabulary matters to you. If you rarely talk about illness, you can skip it for now.

Save rendre un rapport if you use French for work or school. If not, rapport may be too specific.

Mark demain as Learned if it is already instant for you. You do not need to review it, but seeing it in green can remind you that part of the sentence is already easy.

The point is not to save the whole sentence. The point is to label the words by what you need from them next.

Save Phrases More Often Than Single Words

A word is not fully learned just because you know one translation. Paul Nation's work on vocabulary knowledge describes knowing a word as knowing its form, meaning, use, collocations, grammar behavior, and limits. Cambridge's summary on knowing a word gives a useful overview.

That matters in practice. If you save only casa equals house, you miss phrases like en casa, a casa, and casa de mis padres. If you save only decision equals decisión, you may miss tomar una decisión, which is what you need when speaking.

The useful unit is often the smallest natural phrase. Save one word when one word is enough. Save the phrase when the phrase teaches the pattern.

Good phrase candidates include:

  • Verb patterns: se rendre compte de, avoir besoin de, look forward to, den Tisch decken.
  • Noun combinations: strong coffee, public transport, un rendez-vous médical.
  • Polite formulas: could you please, je voudrais, ich hätte gern.
  • Regional expressions: portable in France, cellulaire in parts of Canada.

When to Mark a Word as Learned

Learned should not mean "I saw this once." It should mean "I can recognize this quickly enough that it no longer needs the same attention."

A good Learned test is fresh context. If you meet the word in a new sentence and understand it without stopping, it may be ready for Learned. If you can also use it correctly in your own sentence, even better.

Use Learned for words that have become familiar through repeated exposure. That might happen through generated texts, articles, conversations, radio captions, flashcards, or anything else you read and hear. The important part is not the source. The important part is that the word no longer feels fragile.

Be honest. Marking a word Learned too early can make the green highlight lie to you. Leaving a word in Learning for a little longer is usually fine.

How to Review Saved Words

Learning still needs retrieval. Roediger and Butler's review on retrieval practice explains that trying to recall information can support long-term retention better than simply rereading it.

Review should make you retrieve, not just look. Try this:

  1. See the word: Look at the saved word without the answer.
  2. Recall first: Guess the meaning before checking.
  3. Check the context: Read the sentence where you found it.
  4. Use it once: Say or write one true sentence using the word or phrase.
  5. Promote later: Move it to Learned only after it feels quick in new context.

This is where Learning and Learned are useful. Learning is the active shelf. Learned is the known shelf. You can move words between them when your confidence changes.

How Many Words Should You Save?

For a traditional review session, 3 to 8 serious new items is still a good target. That keeps review manageable.

For LingoUnify's Learning state, you can be more flexible. If you are reading and want the overlay to recognize ten or fifteen useful words over time, that can make sense. They do not all need the same depth of study today.

Use this filter:

  • Save as Learning: useful, recurring, personally relevant, phrase-based, or confusing in context.
  • Mark as Learned: already familiar, quick to recognize, and useful to count as known.
  • Skip or remove: rare, irrelevant, obvious from context, too technical, or cluttering your reading.

The right number is the number that keeps reading easier next time. If the overlay starts feeling noisy, remove weak words or move obvious ones to Learned.

Honest Limits

The overlay can make vocabulary visible, but it cannot decide understanding for you.

Do not confuse highlighted words with fluency. You still need reading, listening, speaking, writing, and time. A green word is a helpful signal, not a certificate.

Translations also need judgment. Dictionaries, teachers, native speakers, corpus examples, and AI tools can all help, but any single explanation can be incomplete. If a word matters, check more than one example. If a generated explanation sounds strange, verify it before building a habit around it.

Non-LingoUnify tools can help too. Anki is strong for custom spaced repetition. A paper notebook can work if you actually review it. Graded readers are useful because they repeat level-appropriate words naturally.

Use the simplest system you will maintain.

What to Do in Your Next Session

Use this routine with your next text.

  1. Read for meaning first: Do not stop at the first unknown word unless the sentence breaks.
  2. Tap useful words as Learning: Save words you want highlighted, translated, or easy to find again.
  3. Mark obvious words as Learned: Use green for words you already recognize quickly.
  4. Review a small core: Pick 3 to 8 Learning words that deserve real recall practice.
  5. Change your mind freely: Move Learning to Learned, Learned back to Learning, or remove the word when it no longer helps.
  6. Keep reading: The point of saving words is to make the next text easier, not to turn every text into admin work.

The quiet skill is not saving everything. It is teaching your reading surface what still needs attention and what is already yours.
