Usage notes

Words ending in -ão are pluralised differently depending on its origin:

• Those in which the suffix is derived from Latin -ōnem (including all masculine augmentatives), as well as words derived from French words ending in -on, Italian words ending in -one or Spanish words ending in -ón (all from Latin -ōnem as well), are pluralised with -ões.
• Those in which the suffix derives from Latin -ānus (“-ian”), as well as words derived from other Latin words ending in -ānus, such as mão and chão, are pluralised with -ãos.
• Some words ending in -ão pluralise as -ães. In these cases the -ão is either not a suffix and derives from Old Portuguese -an, from Latin -ānem, -anēs, or derived from an -an suffix in Old Gallician-Portuguese which has become assimilated regardless of its derivation.
  • cão (“dog”) → cães (“dogs”), from Latin canem, canēs
  • pão (“bread”) → pães (“breads”), from Latin pānem, pānēs
  • capitão (“captain”) → capitães (“captains”), from Old Galician-Portuguese capitan, from Latin capitāneus
  • alemão (“German”) → alemães (“German(s)”), from Old Galician-Portuguese aleman, from Latin Alemannus
• Some words have non-predictable pluralisations, for example:
  • aldeão (“villager”) and vilão (“villain”) may be pluralised with -ãos, -ões or -ães
  • damão (“hyrax”) → damões (“hyraxes”), from French daman (“hyrax”), from Arabic دَمَان إِسْرَائِيل (damān ʔisrāʔīl).
