Usage
What does self- mean? Self- is a combining form used like a prefix meaning “self,” in a variety of senses. Often, it is used to mean "of the self," "independent," or "automatic." In many instances, it is separated from the second element with a hyphen, as in self-government. It is often used in a variety of everyday and technical terms. Self- comes from Old English self, meaning “self.”
Etymology
Origin of self
First recorded before 900; Middle English; Old English self, selfa; cognate with Dutch zelf, German selb-, Old Norse sjalfr, Gothic silba; akin to Irish féin, Latin suī, sē
Explanation
Your self is your sense of who you are, deep down — your identity. When you let someone else know you well, you reveal your true self to them. If the subject of your thoughts is you, you're thinking about your self — or, alternately, yourself. There are parts of your brain that make it possible for you to think about the concept of self, and schools of philosophy devoted to exploring why people have a unique sense of self. Psychologists also study the development of the self, or the beginning of self-awareness, in children. Self comes from the Old English, in which it means "one's own person."
