Irregular Comparatives

Level 1

Use 'mejor' for 'better', 'peor' for 'worse', 'mayor' for 'older/bigger', and 'menor' for 'younger/smaller'.

How It Works

In Spanish, just like in English, some of the most common adjectives have irregular comparative forms. Instead of using the standard más...que structure, you use a single, special word.

Here are the four main irregular comparatives you need to know:

  • bueno/a (good) → mejor (better)
  • malo/a (bad) → peor (worse)
  • grande (big) → mayor (bigger, older)
  • pequeño/a (small) → menor (smaller, younger)

Key Points:
1. Gender: These four words do not change for gender. It's 'mejor' for both masculine and feminine nouns.
2. Number: They do change for plural nouns. Just add an '-es': mejores, peores, mayores, menores.
3. Age vs. Size: While 'mayor' can mean 'bigger' and 'menor' can mean 'smaller', they are most commonly used to talk about age ('older' and 'younger'). For physical size, it's often more common to use 'más grande' or 'más pequeño'.

  1. Este libro es mejor que el otro.

    This book is better than the other one.

    Word by Word: This book is better than the other.

  2. El clima hoy está peor que ayer.

    The weather today is worse than yesterday.

    Word by Word: The climate today is worse than yesterday.

  3. Mi hermano es mayor que yo.

    My brother is older than me.

    Word by Word: My brother is older than I.

    'Mayor' is used here to compare age.

  4. Mi hermana es menor que yo.

    My sister is younger than me.

    Word by Word: My sister is younger than I.

    'Menor' is used here to compare age, which is its most common use.

  5. Estas manzanas son mejores que esas.

    These apples are better than those.

    Word by Word: These apples are better than those.

    Note the plural form 'mejores' to agree with 'manzanas'.

Common Mistakes

  • Using 'más bueno' instead of 'mejor'.

    Este restaurante es más bueno que el otro.
    Este restaurante es mejor que el otro.

    When you compare quality or skill, use 'mejor' (better) and 'peor' (worse) rather than 'más bueno' or 'más malo'. One nice exception: 'más bueno' and 'más malo' are correct when you describe a person's kindness or wickedness, as in 'Es más bueno que el pan' (He is very kind).

  • Saying 'más mayor' instead of just 'mayor'.

    Mi abuela es más mayor que mi mamá.
    Mi abuela es mayor que mi mamá.

    'Mayor' already means 'older', so adding 'más' is redundant — say 'mayor', not 'más mayor'. Note that 'mayor' is the standard word for comparing ages, but 'más grande' and 'más chico' are widely used for 'older' and 'younger' in much of Latin America.
