obliterate

Obliterate means to completely destroy or wipe out something, making it non-existent. When we obliterate something, we leave nothing behind.

Imagine you're playing with Legos and you accidentally knock over a huge castle you built. If your brother comes along and just sweeps it all away without even trying to save any of the pieces, that's what it means to obliterate - he got rid of everything completely. On a bigger scale, cities have been obliterated by wars or natural disasters, meaning they were totally destroyed and nothing remains.

Sometimes we talk about a person obliterating their past, which can mean erasing all memories of something that happened before. It's like hitting the reset button on your life, making everything fresh start from scratch.
