In this example, the speaker is describing how the person they're talking about seems to have two distinct personalities that emerge in different settings.


    The idiom "alter ego" has multiple meanings, all centered around the idea of a second self or hidden identity. It can refer to someone's dual identity, a trusted confidant, or the subconscious self.

    In all of these meanings, the phrase emphasizes the idea of a separate self that is different from the person's outward appearance or known identity. It can be used in a lighthearted or playful manner to describe someone's alter ego, but it can also have a deeper connotation when referencing the subconscious self.

    Origin of "Alter ego"

    The phrase "alter ego" originated from Latin, where it literally translates to "other I" or "second I." It was first used in English in the late 18th century, and was originally used in a legal context to refer to a person's second self in court.

    Over time, the phrase gained a more general meaning and was used to describe a person's second self or hidden identity in everyday language. It has also been popularized in literature and popular culture, with many famous characters having alter egos. One notable example is the superhero Batman, who has a secret identity as Bruce Wayne. This usage of the phrase has further solidified its meaning as a dual identity or hidden self.
