What is an example of theme?

Some examples of themes are overcoming adversity, love, and friendship.

A theme is the subject of a talk, a piece of writing, a person's thoughts, or an exhibition; a topic, so a theme could be almost anything.

Answer 2: Also, experienced speakers and writers know the value of having a theme. For example, when preparing a speech or lecture, the theme helps to focus attention on a narrower field of information and to think more deeply about it. The result is that instead of superficially touching on many points, they develop material in a way that is more beneficial to their audience. When each of the main points is directly connected to the theme and helps to develop it, the audience is also helped to remember those points and to appreciate their significance. Take the idea that the them is the particular viewpoint from which you develop your subject. Repetition of key words from the theme is like the recurring melody of a musical composition.
