After a card is created in Translation mode, flangu generates a set of linguistic metadata for it automatically. This article explains what each field contains, why some cards receive fewer fields than others, and what to do if the AI gets something wrong.
For manual cards, metadata is not generated automatically. You can request it from the card detail screen. The fields are identical once generated.
The metadata fields
Each card panel has an icon row at its bottom. Tapping an icon expands a section below the word. The sections described here correspond to those icons.
Synonyms
The front panel shows 
Synonyms: a list of words in the front language that share a similar meaning with the front word.
Synonyms describe semantic similarity within the same language. They are not translations.
For example, if the front word is "fast," synonyms might include "quick" and "rapid."
Alternatives
The back panel shows 
Alternatives: other valid translations of the front word that were not chosen as the primary back.
Alternatives are translations, not synonyms. They represent different but equally correct ways to translate the front word into the target language. Each alternative is shown with a part-of-speech abbreviation so you can compare the options by grammatical category.
For example, if the front is "fast" and the back is "schnell," alternatives might include "rasch" or "flott."
Note
Alternatives are also shown as a tappable list immediately after translation on the 
Translator screen, before the card is finalized. Tapping one there replaces the card's back text and regenerates all metadata for the new translation pair. This is covered in Creating a flashcard.
Definitions
Each panel can have a 
Definition: a short explanation of what the word means, written in that panel's own language. The front definition explains the word in the source language. The back definition explains it in the target language.
Not every card receives a definition. The part-of-speech gating rules that determine this are explained in the next section.
Example sentences
Each panel can have multiple 
Example sentences showing the word used in a real context.
The examples are displayed in a carousel. Swipe left or right to move between them. The front and back carousels are synchronized: if you are on example 2 on the front, the back also shows example 2.
Inside each sentence, the relevant word or phrase is highlighted in blue. This makes it easy to locate the word in longer sentences.
Each example sentence has its own audio. Tap the sentence to hear it spoken.
Note
Free users see one example sentence per side. Additional examples require flangu Pro.
Pronunciation
The Pronunciation section shows a written representation of how the word sounds. For languages that use non-Latin scripts, this is a romanization. For languages that use a Latin script, it may be an IPA transcription.
Pronunciation is text, not audio. The speaker icon next to the card word plays synthesized speech. These are separate features and can coexist on the same card.
Part-of-speech gating
Each card is assigned a part of speech when metadata is generated. This classification determines which fields the card receives.
Cards classified as sentences or questions do not receive definitions. A sentence or a question does not have a definition in the linguistic sense.
Cards classified as nouns, verbs, adjectives, or proper nouns are eligible for a vocabulary image. Other parts of speech are not. If your card does not show an image icon, its part of speech is the reason.
All other metadata fields, such as synonyms, alternatives, examples, and pronunciation, are generated regardless of part of speech.
The part of speech is assigned automatically and is not directly editable. If the assignment is clearly wrong, you can report it using the method described below.
Reporting incorrect metadata
If a definition, translation, synonym, or any other field looks wrong, you can flag it directly from the Translator screen.
On the back card panel, after a card has been created, a small feedback icon appears at the bottom right of the icon row. Tap it to open the report form.
The form lets you select which fields are incorrect and add an optional note. You can flag one field or several in the same report.
| What happens after you submit |
|---|
| Your report is recorded. |
| The card itself is not changed. The metadata on your card stays as-is until you edit it manually. |
| Reports are reviewed by the flangu team. If the data is corrected, the fix is stored in the shared cache and applies to new cards. Existing cards are not updated automatically. |
You can update your report at any time by tapping the feedback icon again and resubmitting. Each user can hold one active report per translation pair.
