expression, i-adjective
unable to speak (from emotion); soundless; mute
Describes a state where overwhelming emotion (joy, sorrow, shock) makes one unable to produce words or voice. Often used in literary or expressive contexts. The 'soundless' and 'mute' glosses are less common and usually refer to a voiceless cry or scream.
感動で声にならない叫びをあげた。
I let out a voiceless cry from being so moved.
彼女は悲しみのあまり声にならない声でつぶやいた。
She murmured in a voice that was barely a voice, overcome with sadness.
