Etymology 2Edit

See the etymology of the main entry.



  1. dative masculine singular of -illus
  2. dative neuter singular of -illus
  3. ablative masculine singular of -illus
  4. ablative neuter singular of -illus



From Old Spanish -iello, from Latin -ellus, and extension of -lus.


-illo (feminine counterpart -illa)

  1. Added to masculine nouns to denote a diminutive form.

Usage notesEdit

  • If the noun has a final vowel (usually -o), it is dropped before adding -illo.
  • In most cases, -illo is used simply to indicate a small or endeared thing, without changing the basic meaning of the noun; however, in some cases, it is used to effect a greater change in meaning, such as bolsillo (pocket), from bolso (handbag, purse).
  • Different nouns tend to prefer different diminutive suffixes (see synonyms below), though some nouns accept multiple diminutives, and there is often regional or personal variation.
  • For masculine nouns ending in -a, there is some alternation between the gender-reflecting diminutive -illo and the ending-reflecting diminutive -illa. When the latter is used, -ill- may be considered an infix.
