What is the difference between dis and de?

"Dis" is a prefix that generally means "apart," "away," or "not," and is often used to convey negation or reversal, as in "disagree" or "dislike." In contrast, "de" is a prefix derived from Latin that means "from," "down," or "away," and is often used to indicate removal or reversal, as in "dehydrate" or "deconstruct." While both prefixes suggest a form of separation or negation, their specific applications and etymological roots differ.
