IPA: /ɪˈnɔːdəbli/
KK: /ɪˈnɔːdəbli/
In a way that cannot be heard or is too quiet to be heard.
She spoke inaudibly during the meeting, so no one could understand her.
Inaudibly → It is formed from "in-" (meaning not) and "audibilis" (from Latin, meaning able to be heard) and the suffix "-ly" (meaning in a manner). The word "inaudibly" means in a manner that cannot be heard.
Think of 'not' ('in-') being able to be 'heard' ('audibilis') — that's why inaudibly means something that cannot be heard.
