A dictionary lists such an adjective as fortis, forte. Omnis, omne, brevis, breve and dulcis, dulce follow the same pattern.

Compare the ablative of a noun with the ablative of an adjective: cum patre forti (with a brave father). The noun ends in -e and the adjective in -i.

The accusative plural can also end in -is: fortis. The ending -es is the one to learn first.

Examples (5)

  1. Via brevis est.

    The road is short.

    Brevis is the nominative singular, to match the feminine noun via.

  2. Puella fortem puerum videt.

    The girl sees a brave boy.

    Fortem is the accusative singular masculine.

  3. Iulia cum puero forti ambulat.

    Iulia walks with a brave boy.

    Forti is the ablative singular. The adjective ends in -i.

  4. Omnia dona bona sunt.

    All the gifts are good.

    Omnia is the neuter plural of omnis.

  5. Vox sacerdotis dulcis est.

    The priest's voice is sweet.

    Dulcis agrees with vox, which is feminine.

Common Mistakes

  • Giving a third declension adjective a second declension ending.

    Puer fortus est.
    Puer fortis est.

    Fortis has no separate -us and -a forms. One form, fortis, serves for a boy and for a girl.

  • Using the masculine plural with a neuter noun.

    Omnes dona bona sunt.
    Omnia dona bona sunt.

    Dona is neuter plural, so the adjective needs the neuter plural omnia. Omnes goes with masculine and feminine nouns.
