What does the term "indelible" mean?

The term "indelible" refers to something that cannot be erased, removed, or forgotten; it implies a sense of permanence. When something is described as indelible, it often pertains to marks, impressions, or memories that leave a lasting impact, either physically or emotionally. For example, indelible ink cannot be washed away, and indelible memories are those that remain vividly in one’s mind.

This concept of permanence is the key reason why the choice indicating "permanent" aligns perfectly with the meaning of "indelible." Other options such as "temporary," "fleeting," and "vague" suggest transience or lack of clarity, which stand in direct contrast to the enduring quality associated with indelible things. Thus, the choice that denotes permanence effectively captures the essence of the term.
