The Meaning Behind the Words “Disloyal” and “Unloyal”

Example: “The soldier was punished for his disloyal actions toward his comrades.” - Unloyal: The prefix un- simply negates the root word, making unloyal mean not loyal or lacking loyalty without necessarily implying betrayal.
Example: “The dog was described as unloyal, often wandering away from its owner.”
Key takeaway: Disloyal often carries stronger emotional weight, suggesting betrayal, while unloyal feels less intense and is rarely used in modern English.
