Where the phrase comes from (simple): The phrase likely comes from the physical idea of lowering the voice until the words flow near the breath rather than out into the room. English speakers have used similar phrasing for centuries. While exact first use is hard to find, the image is simple: a person speaks near or into their own breath instead of projecting words.

Tone and register: when to use the idiom
Informal and conversational:
- The idiom is informal. Use it in everyday speech, fiction, or casual writing.

Avoid in formal writing:

Parts-of-speech example (sentence showing register):

Practical tips for writers and speakers
- Choose tone first. Decide whether the phrase shows anger, humor, secrecy, or politeness. That determines verbs (mutter, whisper, say).
- Use correct possessive pronouns. Under my/her/his/their breath — include the pronoun.
- Mind punctuation in dialogue. Commas and periods often sit inside quotes in American style: “No,” she said under her breath.
- Avoid in formal writing. Use whispered, murmured, or said quietly instead.
- Be specific when needed. If what was said matters, quote it or paraphrase: She muttered under her breath, “Not again.”
- Vary verbs for style. Muttered suggests annoyance; murmured suggests softness; whispered suggests secrecy or intimacy.
- Watch for redundancy. Don’t write she whispered under her breath—whispered already implies low volume. Better: she muttered under her breath or she whispered.
- Use body language cues. Add small actions to set tone: she rolled her eyes, muttered under her breath, and left.
- Proofread for clarity. Ensure the subject and verb are clear and pronouns have clear antecedents.
- Practice with short dialogues. Write lines using the idiom in different moods to learn its nuance.
