Other forms: selves
The self is the person you essentially are. A sense of self, my former self, true to yourself.
Whether there is a single continuous one is a genuine question rather than a rhetorical one — philosophers and psychologists both doubt it, and the sense of being one person over time may be a story the brain tells. As a prefix it is everywhere: self-service, self-respect. Note that the word is Old English.
