Latin for Duolingo: 2nd Declension, Lesson 1

Please note this course is now available on Wikiversity

Salvete! This lesson continues with the informal, unofficial Latin lessons in the style of Duolingo. It has been going on for a few months now and you might want to check out previous lessons and vocabulary if you’ve missed them:

New Grammar
Latin nouns are divided into 5 basic classes, called declensions. Within each declension, there are singular and plural endings for each of the 5 cases (really there are 7 but the main 5 are enough to start with!) All of the noun, pronoun and adjective functions are covered by these cases. The key to mastering nouns is to recognize what declension it belongs to, and apply the appropriate endings within that declension for its function in the sentence.

We’ve covered the 1st declension nouns in the previous series of lessons; they are mostly feminine (with some masculine exceptions) and follow the pattern of a, ae for their nom. and gen. endings. Now let’s add the 2nd declension. These nouns divide into either masculine or neuter. Masculine nouns follow the pattern of either us, i or r, i for their nom. and gen. s. (Of the ones ending in –r, some drop the preceding vowel for the genitive -- which, just as a reminder, also forms the stem-- but some do not; e.g. ager, agri; liber, libri; but vir, viri and puer, pueri). Neuter nouns follow the pattern of um, i.

Several nouns can have interchangeable masculine 2nd declension endings or feminine 1st declension endings to indicate gender of a person or animal: ursus/ursa, lupus/lupa, servus/serva, amicus/amica.

For now, let’s focus on just two cases of the 2nd declension, nominative and accusative. You’ll notice that it is only in these two cases that there is any difference between the two genders. Also, neuter nouns have the same endings in nominative and accusative. This is true for all neuter nouns regardless of declension. And you’ll probably notice the potential confusion between neuter nom./acc. pl. endings of the 2nd declension and the nom./abl. s. endings of the 1st declension: both are “-a.” The best remedy for this is being very careful to classify your nouns as to declension right when you learn them, and review them frequently, along with the declension endings, until they enter long-term memory.

case name | sing. | pl. | typical use
nominative (m.) | -us/-r | -i | subject or predicate noun
nominative (n.) | -um | -a | “
genitive | -i | -orum | possession, the “of” case
dative | -o | -is | indirect object, the “to/for” case
accusative (m.) | -um | -os | direct object (also some objects of preps.)
accusative (n.) | -um | -a | “
ablative | -o | -is | objects of prepositions, etc. “by/with/from” case

A note on the lessons: As I introduce the noun declensions and cases systematically, I’m diverging from just copying the standard Duolingo tree format so we can focus on learning one grammatical concept at a time. But once we have the first three declensions down it might be easier to do some of the simpler topical skills like “food” or “animals” or “family.” I’m introducing some of those vocabulary words as they are applicable so we will have a base to build on. I recommend going through the lessons sequentially because each new lesson will incorporate some review vocabulary and concepts. I honestly don’t know if this is the best or most effective method of learning Latin but I’m having fun and giving it my best effort. I hope it helps you even a little as it exists now. Just think of the potential when this or something like it is fully interactive!

Next lesson: more 2nd declension nouns and the ablative case. Valete!

In the memrise for this lesson, why is it “multae feminae magnas insulas vident”? I keep getting that wrong because i type insulas magnas instead, as it seems to me that adjective after noun has been the convention till now ( yep i get that it is infinitely flexible and how much work that would be to plug into memrise all the variatons thus my wondering why the variation now)


It's not a hard rule, but adjectives of quantity (how large? how many?) usually precede the nouns, that's why I tried to be consistent in the memrise course and in case of the sentences containing 'multus' and 'magnus/parvus' prefer solutions with these adjectives before the nouns they belong to.


Oh okay , thanks! Didn't realize that. So in the exercises, look for and expect multus / magnus / parvus before their nouns. Gotcha! And thanks for all your work on this it is brilliant!
