English Translation
Mary loses her temper easily.
Wrong word split… 癇癪（かんしゃく）is one word. But the current cloze is すぐにかん{{しゃく}}を.
癇癪 means “a hot temper”. And a person who has a hot temper is called 癇癪持ち（かんしゃくもち）.
- The first character 癇（かん）means “a twitch” or “an epilepsy”.
- The second character 癪（しゃく）means "to get upset). お前の態度は癪に障る（おまえのたいどはしゃくにさわる）, for example, means “your bad attitude makes me irritated”.
