Edited by Harlon Moss || By Janet White || Published on December 29, 2023
What is used to ask for information about something, referring to things or activities. Why is used to inquire about the reason or purpose behind something.

Key Differences

What is used to identify or inquire about something, seeking information about its nature, identity, or purpose. It focuses on the object or subject of the question. Why, in contrast, seeks explanations or reasons, delving into the cause or rationale behind an action or situation.
When someone asks what, they seek to understand 'what' is happening, 'what' something is, or 'what' details pertain to the subject. It's about defining, identifying, or describing. Why goes beyond the surface, aiming to understand the underlying reasons or motivations, asking for the cause or justification.
The question what is often the starting point of inquiry, asking for basic information or clarification. It can pertain to facts, definitions, or details of a situation. Why takes the inquiry deeper, probing for understanding, causes, and reasoning, often leading to more complex discussions.
In research or investigation, what often relates to the gathering of facts and data – 'what' is observed, 'what' are the characteristics. Why is more analytical, asking for interpretations or reasons behind those facts and observations.
Usage of what can be in various contexts – asking about objects, actions, or descriptions. It's versatile and foundational in information gathering. Why, while also versatile, is more reflective and analytical, seeking deeper understanding or justification.
