1. 3rd Declension Adjectives Lesson 47
Latin II
April 28-May 2, 2014

2. Third Declension Adjectives
So far, the adjectives we’ve learned belong to the first and second declensions:
bonus, bona, bonum
sacer, sacra, sacrum
latus, lata, latum
The 3 forms correspond to masculine, feminine, and neuter nominative forms.

3. Third Declension Adjectives
Our new group of adjectives belong to 3rd declension.
Third declension adjectives decline like 3rd declension i-stem nouns, except that they all use –i instead of –e in the ablative singular (like the neuter i-stem nouns do).
Let’s see what some of these adjectives look like in your vocabulary list…

4. Third Declension Adjectives
celer, celeris, celere: swift, quick
facilis, facile: easy, doable
fortis, forte: strong, brave
omnis, omne: all, every
par, paris (gen.): equal, equal to (+ dat.)
BUT WAIT! Why don’t they all have 3 forms, like our old –us,-a,-um friends from long ago?

5. Third Declension Adjectives
celer, celeris, celere
facilis, facile
fortis, forte
omnis, omne
par, paris (gen.)
Just because all 3 genders aren’t listed doesn’t mean they don’t exist.
celer, celeris, celere
facilis, facilis, facile
fortis, fortis, forte
omnis, omnis, omne
par, par, par
Often the masculine/feminine forms are identical, so they’re only listed once, like in facilis, fortis and omnis.
