Etymology
Origin of disintegrate
Explanation
Soak your tooth in a cup of soda for long enough and it will disintegrate, or break apart from decay. The word disintegrate comes from a combination of the prefix dis- meaning "do the opposite of" and the Latin integrare meaning "to make whole." When something disintegrates, it does the opposite of become whole; it falls apart. Objects can either disintegrate over time — like a tooth soaking in a cup of soda, or instantaneously — like a building disintegrating into dust from an explosion.
