-ável

• -able (Beira, Northern Portugal)

From Old Galician-Portuguese -avel, from Latin -ābilis. Compare -able dialectally and in various other languages; e.g. Sicilian -àvili, for a similar morphology.

• Rhymes: (Brazil) -avew, (Portugal) -avɛl
• Hyphenation: -á‧vel

-ável m or f (adjective-forming suffix, plural -áveis)

1. -able

   ‎cantar (“to sing”) + ‎-ável → ‎cantável (“singable”)

   ‎aumentar (“to increase”) + ‎-ável → ‎aumentável (“increasable”)

• This suffix is generally appended to 1st-conjugation verb stems and, in some cases, to Latin stems.
• Some words ending in -ável are directly descended from Latin instead of being formed from a stem and a suffix.
