ItalianEdit

Etymology 1Edit

From Latin -eus.

PronunciationEdit

SuffixEdit

-eo m (feminine -ea, masculine plural -ei, feminine plural -ee)

  1. Used to form adjectives referring to the qualities of the root noun; -en, -eous, -ean
Usage notesEdit
  • Terms formed with this suffix are stressed on the antepenultimate (penultimate if the sequence eo is interpreted as vowel + glide).
  • The suffix is attached to the stem of a noun indicating a material or substance to express material composition:
Examples:
ferro (iron)ferreo (made of iron)
argento (silver)argenteo (made of silver)
acqua (water)acqueo (made of water, watery)
  • When the root is a proper noun, the adjective indicates relation:
Examples:
Cesare (Caesar)cesareo (Caesarean, of or pertaining to Julius Caesar)
Medicimediceo (of or pertaining to the Medici family)
  • In some cases, adjectives descending from Latin exhibit fossilized characteristics which are otherwise lost in the root noun:
Examples:
corpo (body)corporeo (bodily, corporeal) (cfr. Latin corpor-, oblique stem of corpus)
legno (wood)ligneo (wooden, made from wood) (cfr. Latin lignum)
oro (gold)aureo (golden, made of gold) (cfr. Latin aurum)
Ercole (Hercules)erculeo (Herculean, pertaining to Hercules) (cfr. Latin Herculēs)

Etymology 2Edit

From Latin -aeus, from Ancient Greek -αῖος (-aîos).

PronunciationEdit

  • IPA(key): /ˈɛo̯/
  • Stress: -èo

SuffixEdit

-eo m (feminine -ea, masculine plural -ei, feminine plural -ee)

  1. Used to form adjectives and nouns expressing relation to the root noun; -an, -ean
Usage notesEdit
  • The suffix is attached to place names to derive adjectives expressing a relationship of origin or relation, and to create ethnonyms:
Examples:
Etnaetneo (of or pertaining to mount Etna; person from or inhabitant of the Etna region)
Ragusa (city in Croatia)raguseo (of or pertaining to the city of Ragusa; person from or inhabitant of Ragusa)
  • If the root is a proper noun, the adjective indicates correlation:
Euclide (Euclid)euclideo (Euclidean, pertaining to Euclid)
Augusto (Augustus)augusteo (Augustan, pertaining to emperor Augustus or his time)
  • It can also form adjectives related to body parts:
carotide (carotid)carotideo (pertaining to a carotid)
faringe (pharynx)faringeo (pharyngeal, pertaining to the pharynx)
