(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
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()らせに呆然(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.
火事(かじ)(いえ)(うしな)い、しばらく呆然(ぼうぜん)として(なに)(かんが)えられなかった。
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)()つ, 呆然(ぼうぜん)()つめる). The と particle is essential — 呆然(ぼうぜん)する alone sounds unnatural.

COMMON COLLOCATIONS:

  • 呆然(ぼうぜん)()()くす — to stand stock-still in a daze
  • 呆然(ぼうぜん)()つめる — to stare blankly
  • 呆然(ぼうぜん)自失(じしつ) — stupefied; in a state of shock (four-character compound)

SIMILAR WORDS:

  • 唖然(あぜん)とする — to be dumbfounded; emphasizes speechlessness, often at something absurd or outrageous
  • 茫然(ぼうぜん)とする — variant spelling with the same meaning; 茫然(ぼうぜん) emphasizes vagueness and emptiness
  • 愕然(がくぜん)とする — to be shocked; emphasizes the moment of impact rather than the lingering daze
