Synonym discussion

Sense: noun/1

These words all refer to someone above you at work, but they are not identical. 'Boss' is the everyday word for the person you answer to and can feel personal or slightly informal: Priya asked her boss for Friday off. 'Manager' is more formal and often names an official role in a shop, office, or team. 'Supervisor' is narrower: this person watches your work and checks standards, but may not run the whole business. 'Director' usually suggests a higher rank in a large company or organization. 'Employer' only means the person or company that hires and pays you, so your employer is not always the boss you speak to each day.

Etymology

Old FrenchDutchEnglish

Modern English 'boss' brings together two histories. The 'person in charge' word came from Dutch 'baas', used for a master or overseer and taken into English in North America. A different older word, from Old French 'boce' or 'bosse', meant a lump or hump and gave English the decorative noun for a round raised part. Later English built the verb 'boss' and the informal adjective from the authority sense. That is why one spelling now covers both 'the person in charge' and 'a raised round ornament', even though the two meanings began separately.
