Can you help me get my this lesson's lingq word blue again? I clicked by mistake too fast

Can you help me get my this lesson’s lingq word blue again? I clicked by mistake too fast and I want to restore or regain my lesson’s color.

People have different methods, but LingQ is designed so that the blue words just mean you’ve never seen them before, so it doesn’t make sense to make a word that you’ve seen blue again. Now that you’ve seen it, either mark it known and any highlighting disappears or mark it the level of unknown that you want. My words and phrases are either known or unknown level 1. For me simple is easier.

There is no way to make the words blue again. Just ignore it. They will come up again anyways and you can decide how to deal with them then.

This is the exact same issue as in this thread:

You accidentally marked all the words as known when you finished the lesson too quickly. Since it’s only one lesson, the easiest fix is to go back into that lesson and manually change the words from “Known” back to “LingQ” (yellow words, words you’re learning / studying) status one by one. It’s a bit tedious, but it works.
