Absolute superlative: -ísimo/-ísima

Superlative absolute: -ísimo/-ísima


Se usa para expresar un grado muy alto de una cualidad.

(It is used to express a very high degree of a quality.)

What you’re learning: the absolute superlative (-ísimo/-ísima)

Use -ísimo/-ísima to say “extremely / incredibly / really” with an adjective.

  • llenallenísima = extremely full
  • buenabuenísima = incredibly good
  • interesanteinteresantísimo = extremely interesting

It’s stronger and more expressive than muy + adjective.

Step-by-step: how to form it

  1. Start with the adjective (dictionary form).
  2. Add -ísimo (masculine) or -ísima (feminine).
  3. Make it agree in gender and number.
Base adjective Absolute superlative Agreement reminder
divertido divertidísimo matches plan (m. sing.)
divertida divertidísima matches fiesta (f. sing.)
contentos contentísimos matches a masculine plural group
fáciles facilísimas matches a feminine plural noun (e.g., reglas)

Spelling changes you must watch for (-co/-go/-z)

Some adjectives change spelling to keep the pronunciation.

  • -co-quísimo: ricoriquísimo
  • -go-guísimo: largolarguísimo
  • -z-císimo: felizfelicísimo

Self-check: if you see c / g / z at the end, ask: “Do I need qu/gu/c to keep the sound?”

If the adjective ends in a vowel: drop it

If the adjective ends in -o / -a / -e, remove that final vowel before adding -ísimo/-ísima.

  • lleno → llen- + ísimo → llenísimo
  • interesante → interesant- + ísimo → interesantísimo

Common mistake:

  • interesanteísimointeresantísimo

Accents (tildes): where they go, and what can disappear

  • The superlative ending always carries the stress: -ísimo/-ísima (with í).
  • If the original adjective has an accent, it is often removed in the superlative.
Base Correct Incorrect
fácil facilísimo fácilísimo
tarde tardísimo tardisimo

-ble adjectives: use -bilísimo

With adjectives ending in -ble, Spanish typically uses -bilísimo.

  • amableamabilísimo
  • posibleposibilísimo

How to use it naturally in sentences (and what to avoid)

  • Typical patterns: estar + adjective, ser + adjective, parecer + adjective.

Natural examples:

  • La sala estaba llenísima de gente.
  • La comida estaba buenísima.
  • El proyecto me pareció interesantísimo.

Avoid in this topic: don’t stack intensifiers.

  • muy buenísimabuenísima
  • muy interesantísimointeresantísimo

Quick final checklist (before you answer)

  • Did I choose -ísimo / -ísima / -ísimos / -ísimas to match the noun?
  • If it ends in -o/-a/-e, did I drop the vowel first?
  • If it ends in -co/-go/-z, did I apply qu/gu/c?
  • Did I include the accent on í?
  • Did I avoid muy with the superlative?
  1. It is formed by adding -ísimo or -ísima to adjectives.
  2. If the adjective ends in -co or -go or -z , it changes to -quísimo or -guísimo or -císimo.

Exceptions!

  1. If the adjective ends in a vowel, remove the final vowel before adding -ísimo/-ísima.
