(ぼうぜん)とする

ぼうぜんとする
expression
to be stunned; to be dumbfounded; to stand in a daze
emotion
1. to be stunned; to be dumbfounded; to be dazed
To be so shocked or overwhelmed that one cannot think or react. Describes a state of mental blankness caused by surprise, grief, or disbelief.
その()らせ呆然(ぼうぜん)とした。
I was stunned by the news.
彼女(かのじょ)呆然(ぼうぜん)()()くしていた
She stood there in a complete daze.
After losing my home in the fire, I was in a daze for a while and couldn't think about anything.

Describes a state of shock or stupor where one temporarily loses the ability to think or act. The feeling is caused by something sudden and overwhelming — bad news, an accident, an unexpected sight. It implies a visible, physical stillness.

Usage

Most commonly appears in the past tense (呆然(ぼうぜん)とした) or as a modifier (呆然(ぼうぜん)(), 呆然(ぼうぜん)()つめる). The particle is essential — 呆然(ぼうぜん)する alone sounds unnatural.
