Spanish -ÍSIMO ending for superlative adjectives

Spanish -ísimo ending to form Superlative Adjectives, Learn and Practice

Welcome to our grammar lesson about Spanish superlatives with endings like -ísimo.

Attaching certain suffixes at the end of an adjective is a way to express that adjective to an extreme degree, making it a superlative adjective.

For example, look at this transformation:

  • grande = big
  • grandísimo = very very big, extremely big
A Spanish sentence with "grandísimo"
A sentence with “grandísimo”

Most adjectives form their superlative by attaching the ending -ísimo, but some adjectives attach other suffixes.

We will learn them all in this lesson, providing examples.

At the end you’ll find a Quiz and an Exercise for practice.

Suffixes for superlatives

-ísimo

Most adjectives form their superlative by attaching -ísimo.

Just apply one of these two formulas:

  • If the adjective ends in a consonant, simply attach -ísimo at the end. Pay attention to possible consonant transformations, such as “z” becoming “c” :

Base FormSuperlativeMeaning: "extremely..."
débildebilísimoweak
fácilfacilísimoeasy
difícildificilísimodifficult
felizfelicísimohappy


  • If the adjective ends in a vowel, first remove that vowel, then attach -ísimo. Again, pay attention to possible consonant transformations:

grandegrandísimobig
guapoguapísimohandsome

-císimo

Adjectives whose masculine singular form ends in “-n” or “-or”, usually form their superlative by adding -císimo:

Base FormSuperlativeMeaning: "extremely..."
jovenjovencísimoyoung
mayormayorcísimoold
habladorhabladorcísimotalkative
inferiorinferiorcísimoinferior
superiorsuperiorcísimosuperior


-bilísimo

Adjectives ending in “-ble” form their superlative by changing that final “-ble” for -bilísimo.

Base FormSuperlativeMeaning: "extremely..."

Base FormSuperlativeMeaning: "extremely..."
librelibérrimofree
célebrecelebérrimofamous
acreacérrimobitter
salubresalubérrimohealthy

Superlatives with an irregular stem

Some adjectives have a change in the stem when they form the superlative, apart from attaching a suffix.

Here are some examples:

Base FormSuperlativeMeaning: "extremely..."
fuertefortísimostrong
sabiosapientísimowise
antiguoantiquísimoold
fielfidelísimoloyal
ardienteardentísimoardent
calientecalentísimohot
pobrepaupérrimopoor

Accent marks

All superlatives have an accent mark on the attached suffix.

If the original adjective already had an accent mark, it loses it in the superlative form.

For example, “fácil” becomes “facilísimo“. It loses its original accent mark, and adds the one on the attached suffix.

Feminine and plural forms

When we use a superlative adjective in a sentence, we need to match its gender and number to the noun it is connected with.

For example, following the process explained in this lesson, we get that the superlative for “grande” is “grandísimo“. Now we can change its gender and number, resulting in these 4 forms:

masculine singulargrandísimo
feminine singulargrandísima
masculine pluralgrandísimos
feminine pluralgrandísimas

Example Sentences

The following sentences include superlatives.

Notice how they match the gender and number of the noun:

El coche es carísimo.
The car is extremely expensive.

Mi perra es grandísima.
My female dog is extremely big.

Los estudiantes son amabilísimos.
The students are extremely nice.

Las chicas son celebérrimas.

Another type of superlatives: with “más” and “menos”

There is another grammar construction in Spanish we also call superlative.

It is when we express that something is “the most __” or “the least __”, when comparing it with other things.

We have explained that construction in a separate lesson: Spanish superlatives with “más” and “menos”

Here are two examples of this different kind of superlative:

Este coche es el más moderno.
