For a layperson, personality generally refers to the physical or external appearance of an individual. For example, when we find someone ‘good-looking’, we often assume that the person also has a charming personality. This notion of personality is based on superficial impressions, which may not be correct. In psychological terms, personality refers to our characteristic ways of responding to individuals and situations. People can easily describe the way in which they respond to various situations. Certain catchwords (e.g., shy, sensitive, quiet, concerned, warm, etc.) are often used to describe personalities. These words refer to different components of personality. In this sense, personality refers to unique and relatively stable qualities that characterise an individual’s behaviour across different situations over a period of time.

The literal meaning of personality is derived from the word 'persona' which belongs to which language?

Latin

The literal meaning of personality is derived from the Latin word persona, the mask used by actors in the Roman theatre for changing their facial make-up. After putting on the mask, audience expected the person to perform a role in a particular manner. It did not, however, mean that the person enacting the given role necessarily possessed those qualities.
