IPA: /ˈwiːk.deɪ/
KK: /ˈwiːkdeɪ/
A day of the week that is not a weekend, typically Monday to Friday.
I have a meeting scheduled for Wednesday, which is a weekday.
**Weekday** → It is formed from "week" (from Old English *wice*, meaning a period of seven days) and "day" (from Old English *dæg*, meaning a day). The word "weekday" refers to a day that is part of the week, typically a day when work is done.
Think of a 'week' as a period of seven days and 'day' as a single day — a weekday is simply one of those days in the week.
