My father gets up at six o’clock every morning.
You're always up so early! It's still 4 o'clock, you know.
I do 100 sit-ups every morning right after waking up to get rid of my three pack.
This word consists of kanji with hiragana attached. Because the hiragana ends with an う sound, you know this word is a verb. The kanji itself means wake up so the verb vocab version is to wake up.
The reading is the same as the one you learned with the kanji, so tomorrow when you wake up you hopefully won't have to relearn this vocab's reading.
