In Spanish if you want to say, “very, very …” or “extremely …” with adjectives you use the –ísimo ending on the end of any adjective. This blog post looks at how to do this correctly with different endings of adjectives:
e.g. caro = expensive
To say “very expensive” or “extremely expensive” you just take off the last –o and add –ísimo. Make sure the ending agrees with the noun depending on if it is masculine, feminine, singular or plural:
El reloj era carísimo.
The watch was really expensive.
La casa es baratísima.
The house is really cheap.
Los niños estaban buenísimos.
The children were really good.
Las botas son elegantísimas.
The boots are extremely smart/elegant.
Just add –ísimo onto the end of the word.
El examen fue facilísimo.
The exam was really easy.
Los idiomas son dificilísimas.
Languages are really difficult.
Replace it with érrimo/a:
libre (free) > libérrimo
celebre (famous) > celebérrimo
mísero (meager) > misérrimo
Adjectives ending with -able become –bilísimo/a:
amable (kind/lovely) > amabilísimo
agradable (nice) > agradabilísimo
responsable (responsible) > responsabilísimo
Change to –císimo:
trabajador (hardworking) > trabajadorcísimo
superior (superior) > superiorcísimo
joven (young) > jovencito
rico (tasty/delicious) > riquísimo
antiguo (old) > antiquísimo
blanco (white) > blanquísimo
caliente (hot) > calentísimo
cómico (funny) > comiquísimo
feliz (happy) > felicísimo
fresco (fresh) > fresquísimo
largo (long) > larguísimo
Note: If you forget how to add –ísimo or what the rule is for an adjective and don’t want to make a mistake you can also just say “muy + adjective” or “sumamente + adjective” (extremely …).
