Explore can show you far more Arabic than you should save. That is the point. You are not trying to collect every word you see.
Add a word to My Vocabulary when you have a reason to meet it again. Skip it when it is only mildly interesting, too rare for your current level, or tied to a text you do not plan to return to.
Save words you expect to use
Good words usually have a job. They help you understand a book chapter, follow a lesson, read a topic you care about, or say something you are likely to say.
Save the word if one of these is true:
- you have seen it more than once;
- it appears in the book, pathway, or collection you are studying now;
- it unlocks a sentence you want to understand;
- you can imagine using it in speech or writing soon.
If none of those apply, leave it in Explore. You can always come back.
Do not save every difficult word
A hard word is not always a useful word. Some words are too specialised, too literary, or too far ahead of the grammar you know.
That does not make them bad words. It just means they can wait.
If a word feels interesting but not urgent, bookmark it instead of adding it to review. Bookmarks are good for words you may want later. My Vocabulary is for words you are ready to practise.
Keep reviews small enough to trust
Reviews work best when the list is honest. If you add too many words, Learn becomes noisy and you stop trusting the queue.
You do not have to judge "too many" by feel. The dashboard suggests a daily pace: how many new words fit today without overloading future reviews. A small list of words you genuinely want is better than a large list you avoid.
A simple rule
Before saving a word, ask: will I be glad to review this next week?
If yes, add it. If not, bookmark it or leave it.
