What do the black dots mean?

In my lessons some words are underlined with black dots. What does they signify?

They were blue words which you learned (status 4).

Thanks. But I have only a few of them out of the over 18,000 I’ve learned–or at least marked with status 4. Do you know why only these few?

Dunno, but learned words that you’ve ticked (review never), lose the dots. It could be that you’ve mostly chosen the tick status without realising it (like I’ve done in a hurry), or it’s playing up. Cheers

Only LingQs with status 4 will show up in a lesson with dots. If LingQs are status 4 but checkmarked they will appear without the dots in a lesson.

Ah, “ticked” = “checkmarked” :stuck_out_tongue_winking_eye::stuck_out_tongue_winking_eye::stuck_out_tongue_winking_eye::grin:
