Indelible → It is formed from "in-" (meaning not) and "delere" (meaning to erase or destroy). The word "indelible" means something that cannot be erased or removed, signifying a lasting impression or mark.
Think of something that cannot be 'erased' ('delere') — the 'in-' means not, so indelible refers to something that is not able to be erased.
