How to edit a vocabulary list in the iOS app
To remove words from a vocabulary list, first open the app's menu and select "Vocabulary". Then locate the list you want to edit. If you don't see it on the Vocabulary home page, tap on "See all" to the right of "My Lists".
Once you find the list that you want to edit, tap on the number of words in that list to open the list.
Locate the word you want to remove and swipe it halfway to the left side of the screen. This will bring up the yellow "eye" button for excluding a word from the list (keeping it on the list but not in quizzes) and the delete button. If you only want to exclude a word, be careful that you don't swipe all the way off the left side of the screen, since this will engage the delete button and remove the word from the list altogether.
If you're viewing a list that was created by the SpanishDict team or another user, you'll only be able to exclude words. You won't be able to delete words from the list.
