I just realized that the vocabulary 用, is pronounced 'yo-", like its Kanji 用, ie the On’yomi pronunciation.
I was expecting the pronunciation to be ‘mochi’, which seems to be kun’yomi associated to this Kanji.
The vocabulary page only states “This has the same reading as the kanji you learned, meaning you know the reading!”. No warning or mention about this.
In the lower lessons, is it common for a 1-kanji vocabulary to use the kun’yomi pronounciation? Do I need to review all my vocabs over again?
