Latin for Duolingo: Adjectives, Lesson 2

Welcome back to Latin for Duolingo! We are continuing adjectives with the 3rd declension forms this week. If you’re just joining us and want to catch up, here are the links you will need:
- Directory of Lessons
- Vocabulary List
- Memrise course
- Previous lesson: Adjectives 1

New Grammar
Adjectives of the 3rd declension are declined like nouns of the 3rd declension, with a few important exceptions. There is usually no distinction between masculine and feminine, so usually the dictionary listings are for m/f and neuter nominative. (Dictionaries will list m,f,n if there are 3 different forms, and in this case the stem comes from the nom. f. They will list nominative followed by genitive if there is only one nominative form). Third declension adjectives always have the i-stem in the genitive plural, and neuters have i-stems in the nominative and accusative plural. And the ablative singular ending is –i instead of –e. Formatting is difficult for me on Duo, but here's my attempt at a chart:

singular (m/f, n) | plural (m/f, n)
gravis, grave | graves, gravia
gravis, gravis | gravium, gravium
gravi, gravi | gravibus, gravibus
gravem, grave | graves, gravia
gravi, gravi | gravibus, gravibus

Here is a good reference site for 3rd declension adjectives.
Another thing to remember about adjectives (of any type) is that sometimes they are used substantively, that is, taking the place of a noun. We do this in English (The Good, the Bad, and the Ugly) but not nearly as often as in Latin. It will frequently make a big difference if the adjective is m/f (omnes – everyone, all people) or n. (omnia = everything, all things).

Adjectives (3rd declension)
brevis, e = short
difficilis, e = difficult
dulcis, e = sweet
facilis, e = easy
felix, felicis (one form in nom. s.) = happy, lucky, fortunate
fortis, e = strong, brave
gravis, e = heavy, serious, severe
juvenis, e = young
omnis, e = every, all
senex, senis (one form in nom. s.)= old, aged; an old man or woman
similis, e = like, similar (used with gen. or dat. case to complete the meaning)
tristis, e = sad

Now that we have a wide variety of adjectives and nouns, I think the next lesson should be more systematic study of present tense verbs. If you have comments or questions please feel free to add them below, or contact me on my home stream. I will try to respond to them. I am really enjoying coming up with sentences and hope you are enjoying exploring Latin as well.

It would be good to see latin here, I've already learnt it at school but...well...


Gratias tibi ago magistra- ego valde laetus cum ludā tua sum!

Sed questionem de sententiā habeo "Amici mei sunt similes familiae sunt"

Cur haec sententia duos 'sunt' habere debet?


Mea culpa! Tibi gratias ago pro nuntio. Corrigendum est.
