A phrase that contradicts itself is called a self-contradiction, paradox, or oxymoron.
Self-Contradiction
A self-contradiction is a statement that is logically impossible because it contains contradictory elements. It is a statement that cannot be true because it contradicts itself.
- Example: "This statement is false."
Paradox
A paradox is a statement that seems contradictory or absurd but may be true. It is a statement that appears to be self-contradictory but may contain a hidden truth.
- Example: "This statement is true."
Oxymoron
An oxymoron is a figure of speech that combines two contradictory terms. It is a phrase that combines two words with opposite meanings to create a surprising effect.
- Example: "living dead," "jumbo shrimp," "deafening silence."
These terms are often used interchangeably, but there are subtle differences between them. A self-contradiction is a logical impossibility, while a paradox can be true despite its apparent contradiction. An oxymoron is a figure of speech that combines contradictory words for stylistic effect.
