New Grammar

The genitive case is used to show possession, or more broadly, in expressions that use “of” in English. The genitive singular is the marker that tells us what declension a noun belongs in: for the 2nd declension, the genitive singular ending is –i and the genitive plural is –orum. This is true whether the noun is masculine or neuter in gender. Because the gen. s. ending “-i” helps us to classify the nouns in the 2nd declension it is standard to list all nouns with nom. and gen. s. Thus the listing “medicus, i = doctor” tells us that it is a second declension noun because of the –i ending in the gen.s., it is masculine because of the –us ending in the nom., and when we look specifically at the form “medici” we could translate it either as “the doctor’s” or “of the doctor.” Since it is a masculine noun, "medici" could also be the nominative plural form "the doctors"; the difference has to be determined by context. This gets easier with practice.

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

So domini romani are the Roman gods?


Roman gods would be dei romani. Domini romani would be Roman lords. (When addressing God, people often say "Lord," but they are different words.)
