An ambivert is someone who exhibits traits of both introverts and extroverts, and can switch between the two depending on the situation: 

• Adaptability

Ambiverts can easily adjust their behavior to fit the person or situation. For example, they might enjoy a party one night but prefer to be alone the next. 

• Social skills

Ambiverts are often good communicators and listeners, and can be comfortable in social settings. They can also be peacemakers who can bring reason to heated situations. 

• Empathy

Ambiverts are often highly empathetic and can understand the needs and emotions of others. 

• Balance

Ambiverts can balance their introverted and extroverted sides, allowing them to connect with a wide range of people. 

• Leadership and negotiation skills

Ambiverts can be good leaders and negotiators because they can relate to people on different levels. 

Some say that most people are actually ambiverts, and that the term "ambivert" is a more accurate description than "introvert" or "extrovert". However, others argue that the term is an oversimplification of personality traits. 

Another day in the classroom(for me). Introvert and extrovert I knew of. Ambivert, new to me, as was omnivert and now I know about all four. Miss George, my grade one teacher, would have given me a gold star, I think.

Time and again, I have said I like easy to understand answers, with the following, I rest my case.

Introvert, Extrovert, Ambivert & Omnivert
