Marked words while practicing
Is there an explaination why some words are marked in practicing mode?
I assume that yellow marked words are new words. Whats with blue ones ? Are there more colors?
I believe the words highlighted in blue are the ones Duo has specifically selected for you to practice. So if "gato" is highlighted in "Tengo un gato", "gato" is the word that will show up on the "You strengthened X words" screen at the end of the practice. ("Tengo" and "un" are also strengthened, but don't show up on the summary screen at the end).
