Which action involves examining something in detail to understand its meaning?

The action that involves examining something in detail to understand its meaning is analyzing. Analyzing requires breaking down a text or concept into its components to explore how they contribute to the overall meaning. This process typically involves looking closely at various elements such as structure, language, themes, and symbols within the text.

Reviewing, while it can involve assessment, generally focuses on summarizing or evaluating rather than delving deep into the specifics. Discussing entails conversing about a topic, which can include sharing ideas or perspectives but does not necessarily involve detailed examination. Assuming refers to accepting something as true without proof, which is quite the opposite of engaging in a thorough investigation.
