Superlatives with ÍSIMO in Spanish – Learn and Practice

Welcome 😊 to our grammar lesson on Spanish superlatives with -ísimo (and other similar endings).

In Spanish, we can use certain endings to express an 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 adding -ísimo, but some of them add slightly different endings.

By the end of this lesson, you will be able to form these superlatives and use them in sentences.

You will also find a Quiz and an Exercise to practice. Let’s start!

Superlatives with an irregular stem

Some adjectives have a change in the stem when they form the superlative, apart from adding an ending.

Examples:

Base FormSuperlative
fuerte

strong

fortísimo
sabio

wise

sapientísimo
antiguo

old

antiquísimo
fiel

loyal

fidelísimo
ardiente

ardent

ardentísimo
caliente

hot

calentísimo
pobre

poor

paupérrimo

Accent marks

All superlatives have an accent mark on the ending.

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

For example, “fácil” becomes “facilísimo“, losing its original accent mark.

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, the superlative of “grande” is “grandísimo“. But when we use it in sentences, we must match the gender and number of the noun, resulting in 4 possible 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.
