Making Comparisons in Spanish

In English, to create a comparison with an adjective, we generally add an "-er" to short adjectives (happier, stronger, wilder, etc.) or add the word "more" before longer adjectives (more intelligent, more studious, more loving, etc.). There's no Spanish equivalent for the suffix "-er"; we simply precede all adjectives with the word más (more) to make them stronger.

más fuerte (stronger)
más rádido (faster)
más inteligente (more intelligent)
más cariñoso (more loving)

To indicate "less" rather than "more", we precede all adjectives with the word menos to make them weaker.

menos fuerte (less strong / weaker)
menos rápido (less fast / slower)
menos inteligente (less intelligent)
menos cariñoso (less loving)

Comparisons of Inequality with Adjectives

In order to actually compare two objects in a comparison of inequality (one object being more or less ____ than the other), we use the following construction:

subject + linking verb + más/menos + adjective + que + noun

Marcos + es + más + alto + que + su hermana.
(Marcos is taller than his sister.)
Yo + soy + menos + inteligente + que + tú.
(I am less intelligent than you.)
Mi coche + es + más + rápido + que + el tuyo.
(My car is faster than yours.)
La puerta es más roja que una cereza.
(The door is redder than a cherry.)

Comparisons of Equality with Adjectives

While a comparison of inequality compares two objects or people with different characteristics, a comparison of equality means that the two objects have equal characteristics.

In order to make these comparisons, we use the adjective with the expression "tan ... como...", which is like saying "as ... as... ". See the construction below:

subject + linking verb + tan + adjective + como + noun

Marcos + es + tan + alto + como + su hermana.
(Marcos is as tall as his sister).
Yo + soy + tan + inteligente + como + tú.
(I am as intelligent as you.)
Mi coche + es + tan + rápido + como + el tuyo.
(My car is as fast as yours.)
La puerta + es + tan + roja + como + una cereza.
(The door is as red as a cherry.)

Comparisons with Superlatives

Superlatives are also used in comparisons. In English, we create superlatives by placing a definite article before the adjective, to which we add the suffix "-est" (the strongest, the smartest, the nicest, etc.). To turn this into a comparison, we add the group to which the object or person is being compared (She's the prettiest in the class / at the party / of her friends.).

To convey this same concept in Spanish, we use a construction very similar to the other comparison formulas we have reviewed, with the definite article (el, la, los, las) preceding the comparison word (más, menos) and using de instead of que.

subject + verb + definite article + más/menos + adjective + de + rest of sentence

María + es + la + más + guapa + de + sus amigas.
(María is the prettiest of her friends.)
Mi coche es el más caro de todos.
(My car is the most expensive of them all.)
Sara es la menos alta de su clase.
(Sara is the least tall of her class.)
Pedro es el menos rápido de su equipo.
(Pedro is the least fast of his team.)

Comparisons with Adverbs

The same formula is used in comparisons with adverbs, the only difference being that you won't have to worry about gender given that adverbs have only one form. (Need a refresher on how to form the superlative? Take a look at this page: Spanish adverbs)

subject + verb + más/menos + adverb + que + noun

Sara + estudia + menos + diligentemente + que + Marcos.
(Sara studies less diligently than Marcos.)
Su casa + está + más + lejos + que + la mía.
(His/Her house is farther than mine.)

Irregular Comparisons

Both English and Spanish have several "irregular" comparison words, meaning that the adjective changes. Take, for example, the adjective "bad". If we followed normal rules for forming comparisons, we would say "badder" instead of the irregular comparison word "worse". The same goes for Spanish; the word for bad is "malo" but in comparisons instead of saying "más malo" we say "peor".

See a few examples below:

Normal adjective	Adjective in comparison
good = bueno	better = mejor
bad = malo	worse = peor
big = grande	bigger = mayor (referring to age)
old = viejo	older = mayor
young = joven	younger = menor
little = pequeño	littler = menor (referring to age)

Examples in context:

I'm older than my sister. = Yo soy mayor que mi hermana.
My sister is younger than me. = Mi hermana es menor que yo.
Your grades are worse than mine. = Tus notas son peores que las mías.
I drive better than my father. = Conduzco mejor que mi padre.
