Every Day, Daily
noun
Every day is daily (or just every day).
まいにち
This is a jukugo word, which usually means on'yomi readings from the kanji. Since 日 has two on'yomi readings, here's a mnemonic to help you remember which one to use: Every day you watch your favorite program, My Nietzsche (まいにち). It's a daily cartoon about Nietzsche and his life, which you follow religiously. Oh how much you love Nietzsche.
