Everyone has it and no one can ever truly lose it. According to this riddle, what is it?

Introduction / Context:
This classic riddle uses simple language to hide an imaginative answer. When you read that everyone has it and no one can lose it, you are encouraged to think about something that belongs to every person regardless of age, wealth or culture. The puzzle is often asked in classrooms and reasoning exercises to encourage students to consider both physical and abstract interpretations of ownership and loss.

Given Data / Assumptions:
- Every person has the thing being described. - No one can lose it permanently. - The object or concept may not be physically solid like an item you can hold. - The riddle is intended to be solved with creative thinking rather than strict science.

Concept / Approach:
The most common traditional answer to this riddle is shadow. Whenever there is a source of light and a surface, a person casts a shadow. The idea everyone has it refers to this natural effect. The phrase no one can lose it does not mean the shadow is always visible every second, but that as long as the person exists and there is light, the shadow will appear again. In other words, you may not see your shadow at night indoors, but you have not lost the ability to cast one. The riddle focuses on this dependable relationship between a person and their shadow.

Step-by-Step Solution:
1. List things that every person typically has, such as name, face, body and shadow. 2. Check whether each of these can be lost in an ordinary sense. 3. Note that hair and teeth can fall out, and voices can be lost due to illness, so these do not fit. 4. Consider that a face remains but can change, while a shadow always reappears when there is light. 5. Conclude that shadow best matches the description used in the riddle.

Verification / Alternative check:
To verify, imagine different people: a child, an adult and an elderly person. All of them may have different physical features, but all can cast shadows when they stand in sunlight. Hair and teeth can be removed or damaged, while some people cannot use their voice. By contrast, the existence of a shadow depends on the physical presence of the person and a light source, not on wealth, health or other factors. This broad applicability matches the clue everyone has it. The fact that a shadow will appear again whenever conditions are right supports the phrase no one can lose it in the playful sense of the riddle.

Why Other Options Are Wrong:
Hair can be completely lost due to baldness. Teeth may fall out or be removed. A face can be disfigured or hidden, and the phrase losing face even means losing reputation. A voice can be lost or become silent. These options therefore fail the instruction that no one can lose it if interpreted in the natural spirit of the riddle. Shadow is the only option that fits both the universality and the dependable return under light.

Common Pitfalls:
Some learners answer name because they think of legal documents, but names can be changed, forgotten or unknown. Others become confused by the fact that shadows are not visible in total darkness and think that means they are lost. Remember that riddles often exaggerate and simplify, focusing on common everyday experiences rather than rare extreme situations. Interpreting the lines in this spirit makes it easier to accept shadow as the intended answer.

Final Answer:
The riddle describes something that is linked to every person and returns whenever there is light, so the correct answer is shadow.
