IPA: /ˈɔːtəˌdaɪl/
KK: /ˈɔːtəˌdaɪl/
A device or feature that automatically dials a telephone number without needing manual input.
The autodial can save time by calling multiple numbers automatically.
Autodial is formed from "auto-" (meaning self) and "dial" (from Old French *dialer*, meaning to turn or to call). The word refers to a device that automatically dials a phone number by itself.
Think of 'self' ('auto-') doing the action of 'calling' ('dial') — that's why autodial means a device that calls by itself.
