Ethos is the spirit and values that mark a community. The school's ethos, a work ethos, an ethos of service.
In rhetoric it is one of the three appeals beside pathos and logos, and it means persuading by the speaker's own character. In ordinary use it names what an institution is like to be inside rather than what it says it is.
