Today's word is "ukkari (carelessly; thoughtlessly; unconsciously; absentmindedly)". It is written in hiragana.
* Ukkari yakusoku o wasurete shimatta. うっかり約束を忘れてしまった。 --- I carelessly forgot my appointment.
* Ukkari honshin o shabette shimatta. うっかり本心をしゃべってしまった。 --- In unguarded moment, I revealed my true intentions.
