Derivational suffixes (word formation)

Derivational suffixes create new words from existing roots by changing their part of speech or adding specific meaning. They are key to building Spanish vocabulary.
  • -ción: Turns verbs into nouns indicating an action or result (hablar →  hablación)
  • -dad: Forms abstract nouns, often equivalent to English “-ty” (ciudad, libertad)
  • -ito/-ita: Diminutive suffix expressing small size or affection (perro → perrito)
  • -ón/-ona: Indicates largeness or intensity, sometimes pejorative (casa → casón)
  • -er/-or: Forms agent nouns meaning “one who …” (trabajar → trabajador)
  • -ble: Forms adjectives meaning “able to be …” (amar → amable)

Diminutive, augmentative, and superlative suffixes (word nuance)

These suffixes modify the meaning of nouns, adjectives, or even verbs to express small size, affection, largeness, or intensity. They convey emotional nuances beyond literal meaning.
  • -ito/-ita: Small size or affection (gato → gatito)
  • -illo/-illa: Regional variation of diminutive (perro → perrillo)
  • -cito/-ecito: Diminutive formed after consonants or certain endings (pez → pececito)
  • -ón/-ona: Large size or exaggeration (casa → casona)
  • -ísimo/-ísima: Superlative meaning “very” or “extremely” (bueno → buenísimo)

-ísimo/-ísimasuperlativefuerte → fortísimovery strong

very strong (superlative)


fortísimo

-ísimo is a superlative suffix that means “very” or “extremely.”

Gender and number suffixes (agreement)

Spanish nouns and adjectives use suffixes to mark gender (masculine/feminine) and number (singular/plural). These endings are essential for grammatical agreement.
  • -o / -a: Masculine / feminine singular (libro /  libra)
  • -os / -as: Masculine / feminine plural (libros /  libras)
  • -e: Often neutral or invariant for gender (estudiante)
  • -es: Plural form for nouns/adjectives ending in consonants (papel → papeles)
Spanish SuffixEnglish FunctionSpanish ExampleEnglish Example
-o / -amasculine / feminine singularamigo / amigafriend
-os / -asmasculine / feminine pluralamigos / amigasfriends
-esingular (gender-neutral)estudiantestudent
-esplural for consonant endingspapel → papelespaper → papers

In Spanish, how do you form the feminine singular of a noun that ends in -o?


Change the -o to -a (e.g., amigo → amiga).

Masculine nouns ending in -o change to -a for the feminine singular (amigo → amiga).

Summary

Spanish suffixes serve different roles:
  • Inflectional suffixes express verb tense, mood, person, and number (e.g., hablar → hablo, hablaba)
  • Derivational suffixes create new nouns, adjectives, or agents from roots (e.g., leer → lector, -ción, -dad)
  • Diminutive/augmentative/superlative suffixes add nuance of size, affection, or intensity (e.g., gatito, casona, buenísimo)
  • Gender/number suffixes mark agreement for nouns and adjectives (e.g., -o/-a, -os/-as, -es)
Understanding these suffix types helps you handle grammar, expand vocabulary, and appreciate the expressive power of Spanish word formation.
