/ˈmənˌdeɪ/ (US) · CEFR A1 · Noun

## Definition

the first day of the work week, coming after Sunday. Most people see it as the start of the school or business week.

For teachers: the day of the week following Sunday and preceding Tuesday. Traditionally considered the second day of the week in religious calendars, but the first day of the work week in modern secular contexts.

## Examples

- I always feel tired on Monday morning.
- The office is usually very busy on Monday because we have to answer all the emails from the weekend.
- While some employees prefer a slow start to the week, the manager insists on holding the primary briefing every Monday to establish clear objectives for the coming days.

## Pitfalls

- Not "I will see you in Monday" but "I will see you on Monday" — Days of the week take the preposition 'on', not 'in'.

## Usage notes

- Capitalized in all contexts. When used as a countable noun, it refers to a specific instance of the day or a recurring pattern.
