Vocab A16

I know there are levels N5 or N4, but what is A16, another level?

Thanks in advance.

Do you have a screenshot or more context? Not familiar with A16

I think a chunk of it is the vocab imported from Wanikani or such? I’ve found a bunch of words in my vocab that are either E[number] or A[number], not sure what the category means though, for example these:

Thanks, but is it a level?

Hey there,
If I’m not mistaken, those are words that already exist in the database but need to be classified, edited, sometimes deleted, and lack exemple/quizz sentences for now.

They’re not attached to any level at the moment and you can find basic and niche stuff.

Thanks.
