What is the name for a topic or key idea that hold story poem together?

A theme is a topic or key idea that holds a story or poem together. It can be a universal truth, a moral lesson, or simply an observation about life. Themes are often expressed through the use of symbols, imagery, and figurative language.

Some common themes in literature include:

* Love

* Loss

* Hope

* Redemption

* Identity

* Courage

* Freedom

* Justice

* Equality

* Nature

Themes can be either explicit or implicit. Explicit themes are those that are stated directly in the text. Implicit themes are those that are not stated directly, but are instead suggested through the text.

Themes can also be used to compare and contrast different works of literature. For example, the theme of love can be explored in a variety of ways in different stories and poems. By comparing and contrasting how different authors explore the same theme, readers can gain a deeper understanding of the human experience and the world around them.
