When learning Spanish, most students quickly understand how to form regular comparatives with más and menos. However, some adjectives have special comparative forms that do not follow the usual pattern.

In this article, we will explore the irregular comparatives mejor and peor in Spanish, explain how they work, and help you avoid common mistakes.

Irregular Comparatives Mejor and Peor

Understanding irregular comparatives mejor and peor in Spanish is essential because these forms are extremely common in everyday conversation. If you say más bueno instead of mejor, you may sound unnatural in many contexts. Let’s look at how these forms work.

Mejor: The Comparative of Bueno

The adjective bueno (good) has the irregular comparative form mejor (better).

In standard Spanish, más bueno is only used in very specific contexts, usually when emphasizing moral goodness rather than general quality. In the rest of situations, you should use mejor.

Peor: The Comparative of Malo

The adjective malo (bad) has the irregular comparative form peor (worse).

Both mejor and peor are usually followed by que when introducing the second element of the comparison.

When studying irregular comparatives mejor and peor, it is important to practice full sentences, not just isolated words.
