わ

The sentence-ending particle わ adds emphasis, emotion, or a soft, feminine nuance to a statement. It can express astonishment, reassurance, or determination, depending on the context and intonation. It tends to be informal and is more common in feminine speech or older styles; using it in formal situations or by male speakers can sound unusual or theatrical. In some dialects, わ can be used more broadly without the feminine nuance. Often paired with exclamations or strong feelings (e.g., relief, joy, frustration). You should adjust tone and formality when choosing to use わ.
