What does the term 'indelible' mean?

The term 'indelible' means something that cannot be erased or removed. It often refers to marks or memories that leave a lasting impression and are permanent in nature. For example, indelible ink is used because it remains on the surface indefinitely. The concept of indelibility can apply to experiences or emotions that are so profound they stay with a person for a long time, if not forever. This permanence is what distinguishes the correct choice from others that imply transience or insignificance.
