erase
This term describes the act of total removal, whether physical, digital, or psychological. It carries a connotation of permanence and cleanliness, suggesting that the target is not merely hidden or obscured, but completely eliminated so that no trace remains. In a digital or mental context, the word implies a systemic clearing. While "delete" is often used for individual files, "erase" suggests a more comprehensive wiping of a medium or a complete purging of a memory or emotion.
