Attaching “-ísimo” (or sometimes, something slightly different) at the end of an adjective is a way of expressing that adjective at an extreme degree. For example, look at these transformation:

  • grande = big
  • grandísimo = very very big, extremely big

 

We will now explain how to form these adjectives.

 

“-ísimo” adjectives

For most adjectives, you can form their superlative with this system:

  • If the Singular Masculine form of the adjective ends in a consonant, just attach “-ísimo” at the end. Pay attention to possible consonant transformations, such as the final “z” becoming “c”.

AdjectiveSuperlative
fácilfacilísimo
difícildificilísimo
felizfelicísimo

 

  • If the Singular Masculine form of the adjective ends in a vowel, first eliminate that vowel, and then add “-ísimo”. Again, pay attention to possible consonant transformations.

AdjectiveSuperlative
grandegrandísimo
guapoguapísimo
blancoblanquísimo
largolarguísimo

 

“-císimo” adjectives

Adjectives whose Singular Masculine form ends in “-n” or “-or”, will usually add “-císimo” for their superlative form:

AdjectiveSuperlative
jovenjovencísimo
mayormayorcísimo

 

Adjectives which add “-bilísimo”

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

AdjectiveSuperlative
amableamabilísimo
agradableagradabilísimo

 

“-érrimo” adjectives

Some adjectives whose Singular Masculine form’s last syllable contains the letter “r”, add the ending “érrimo” in the following manner:

AdjectiveSuperlative
librelibérrimo
célebrecelebérrimo

 

Feminine and plural forms of Superlatives

As you have seen, in forming the Superlative, we have always taken the singular masculine form of the adjective as our starting point.

But of course, once we have formed the superlative, we can now match it to the gender and number of the corresponding noun.

For example, the superlative for “grande” is “grandísimo”. Now we can match its gender and number to a noun, resulting in one of these 4 posibilites:

  • grandísimo
  • grandísima
  • grandísimos
  • grandísimas

 

Example Sentences

El coche es carísimo. = The car is extremely expensive. (caro = expensive)

Mi perra es grandísima. = My female dog is extremely big. (grande = big)

Los estudiantes son amabilísimos. = The students are extremely nice. (amable = nice)
