This phrase suggests that the speaker is intentionally keeping their voice hushed, as if they were whispering to themselves or to someone nearby. It implies that the person may not want their words to be heard by others, either because they are speaking something secretive, critical, or possibly not socially acceptable. It can also be used to express annoyance, irritation, or dissatisfaction without openly confronting or challenging someone or something.
"Under one's breath" often conveys a sense of muttering or grumbling, typically expressed when an individual is frustrated, disgruntled, or discontented about a particular situation or individual. It can also be used when someone wants to comment or express a thought without disrupting the ongoing conversation, maintaining a level of subtlety and privacy.
In summary, "under one's breath" signifies speaking quietly, softly, or discreetly, often reserved for muttering, murmuring, or whispering words that may be private, critical, dissatisfied, or meant to be heard only by select individuals.
