under one's breath

Quietly, almost inaudibly

Under one's breath describes speech so quiet it's barely audible—muttered, whispered, or mumbled so others can't quite hear: She cursed under her breath as she walked away.

The phrase typically suggests words not meant to be overheard, often complaints, insults, or private reactions: He repeated the answer under his breath to memorize it.
