Learn how to form the Spanish superlative with -ísimo

When we want to say "extremely [adjective/adverb]" in Spanish, we sometimes use the endings -ísimo, -ísima, -ísimos, -ísimas, as an alternative to muy, super, realmente; for example: muy caro, super caro, realmente caro, carísimo.

 

Spanish superlative of adjectives that end in a single vowel

Read and listen to these examples:

Mi mejor amigo Adrián es listísimo.My best friend Adrian is very clever. (adjective: listo)

María es lentísima haciendo los deberes.Maria is extremely slow doing her homework. (adjective: lento)

Los conciertos de la calle son ruidosísimos.Street concerts are the noisiest. (adjective: ruidoso)

Aquí venden unas pulseras carísimas.Here they sell extremely expensive bracelets. (adjective: caro)

La profesora nueva es inteligentísima.The new teacher is really intelligent. (adjective: inteligente)

If the adjective ends in a single vowel, the vowel is removed and replaced by -ísimo, -ísima, -ísimos or -ísimas.

However, note this exception: adjectives that end in -ble, despite having a single vowel -e at the end, follow a different rule, see Spanish superlatives -ísimo with adjectives ending in -co, -go, -ble,-z, -or and -n

Spanish superlative of adjectives that end in -io

If the adjective ends in -io, then both vowels are removed and replaced by -ísimo, -ísima, -ísimos or -ísimas.

Tienes que lavar tu coche; está sucísimo.You have to clean your car; it's extremely dirty. (adjective: sucio)

Nos hemos comprado un apartamento con un salón amplísimo.We've bought an apartment with an extremely spacious living room. (adjective: amplio)

Las instalaciones del hotel están limpísimas.The hotel facilities are extremely clean. (adjective: limpio)

Mis dos cuñados son serísimos.My two brothers-in-law are extremely serious. (adjective: serio)

Mis dos cuñados son seriecísimos.My two brothers-in-law are extremely serious. (adjective: serio)

As you can see in the last examples above, the adjective "serio" (serious) admits two different superlatives: serísimo and seriecísimo

 

Spanish superlative of adjectives that end in -l and -ar

If the adjective ends in -l or -ar, the superlative suffix is simply added to the end of the word (no letters are removed).

Este ejercicio me parece dificilísimo.I find this exercise extremely difficult. (adjective: difícil)

Las preguntas del examen eran facilísimas.The questions in the exam were extremely easy.

Tenemos unos empleados lealísimos.We have some extremely loyal employees. (adjective: leal)

Esos chicos son vulgarísimos. Están siempre diciendo palabrotas.Those boys are extremely vulgar. They're always swearing. (adjective: vulgar)

Esta canción fue popularísima en los años 90.This song was extremely popular in the 90s. (adjective: popular)

 

Spanish superlative of some adverbs

We can also form the superlative of some adverbs with the suffix -ísimo. As adverbs, the form is invariable, so there is no agreement with any noun; we take the adverb, omit the last vowel and add the suffix -ísimo

For example:

lento = slow/slowly

Mi abuela camina lentísimo porque le duelen las rodillas.My grandma walks really slowly because her knees hurt.

rápido = fast/quickly

Cristina conduce rapidísimo.Cristina drives really fast. 

tarde = late

¡Habéis llegado tardísimo!You're very late! [lit: arrived]

temprano = early

Mi padre siempre se levanta tempranísimo.My dad always gets up really early.

suave = soft/softly

Habla suavísimo al bebé.Speak to the baby very softly. 

Exceptions

Bear in mind there are some exceptions/irregularities; for example:

cerca = close/near

- ¿Te acompaño a casa? -No es necesario; vivo cerquísima.-Shall I walk you home? -No need; I live really close.

the superlative form keeps the -a at the end. There is also a consonant change to keep the original sound [k]: c > qu

lejos = far

Ellos viven lejísimos del centro.They live really far from the centre.

the superlative form keeps the -s at the end.

If the adjective or adverb has a written accent [´], when we form the superlative, the original accent is lost and always placed on the í from ísimo, -a, -os, -as.  

For example:

rápido -> rapidísimofácil  -> facilísimo

All superlatives using this suffix have a written accent.

Also bear in mind that some superlatives that come from adjectives containing -ue or -ie may also use a form that imitates the latin origin of the adjective:

fuerte, fortísimo/fuertísimostrong, extremely strong

cierto, certísimo/ciertísimocertain, extremely certain

nuevo, novísimo/nuevísimonew, extremely new

The form that imitates the latin one is perceived as a more educated form, but both are valid.

The only form accepted for the superlative of "antiguo" is the one keeping the latin form, using -qu:

antiguo, antiquísimoold, extremely old
