"My name is Marcus."
Translation:Nomen mihi est Marcus.
Basically, yes. But be aware that while his name is 'Marcus', all nouns (including names) in Latin can have several different forms. So his name is 'Marcus', but it's also 'Marce', 'Marcum', 'Marci', and 'Marco'. This is because nouns (and adjectives) DECLINE--that is, they change form depending on what grammatical case they appear in.
The Latin cases are nominative (subject), accusative (direct object), dative (indirect object), ablative (various uses), genitive (possessive), vocative (addressing someone directly) and some nouns also have a locative case (denotes location).
Here's some example sentences using the word 'Marcus':
- Marcus in urbe studet. (Marcus [nominative] studies in the city.)
- Ego Marcum in urbe uideo. (I see Marcus [accusative] in the city.)
- Ego Marco* in urbe eo. (I go to Marcus [dative] in the city.)
- Ego cum Marco* studet. (I study with Marcus [ablative].)
- Tu discipula Marci es. (You are the student of Marcus [genitive].)
- Marce, tu magister meus est. (Marcus [vocative], you are my teacher.)
*note that 2nd declension nouns like 'Marcus' have identical forms in the dative and ablative, i.e. 'Marco' (singular) and 'Marcis' (plural... 'Marcuses'?) Sometimes you will get a word like 'cum' (with) which goes with an ablative noun (e.g. 'cum Marco' = with Marcus). At other times you just have to work out what case is being used from the context.
It can be daunting for new Latin learners when they figure out that there are multiple forms of every single noun and adjective! But don't worry, you'll get a feel for it sooner than you think. If you're not familiar with grammatical cases, just think of the difference between 'he', 'him', and 'his'. It's exactly the same kind of system. Indeed, 'his' is nominative, 'him' is both accusative and dative, and 'his' is genitive.
Fun fact: The difference between 'who' and 'whom', which so many English speakers struggle with, is that 'who' is nominative and 'whom' is both accusative and dative!
Hope this helps!
Marcus is nominative, Marce is vocative.
Here is a plain-English overview of what the cases are and how they work:
Latin cases, in English
Adjectives must agree in gender, number, and case with the nouns they modify, but they have their own declensions. Sometimes you get lucky and the adjective just happens to follow the same declension as the noun, but that is not a guarantee.
There are many misconceptions surrounding the slight misnomer "free" word order. After all, linguists were able to categorize Latin as a generally SOV language.
"Free" word order is best interpreted as "relatively flexible" word order. There is a preferred default, and some sequences don't happen at all, not even in poetry. For example, Latin does not have definite or indefinite articles ("the" or "a"), but it does have demonstratives ("this/that/these/those") and you would not separate a demonstrative from its noun.
On a larger scale, you would never say "Frater mater dormit scribit Romae in urbe." Who is doing what where?
I believe it is relevant to why it's possible to separate "mihi" from "nomen" that "mihi" is not the genitive "my/mine". It literally means "to-me" and
I believe it is the ablative case it is the dative case.
'ago' is a different verb. It has many potential meanings, but this isn't one of them. 'Nomen mihi agit Marcus' would be something like 'My name does Marcus', or even 'The name Marcus does to me'.
Also, because it is not a copular verb, even if 'ago' was appropriate then it would have to be in the accusative case, i.e. 'Nomen mihi agit Marcum'.
Hope this helps! :)
Actually, now I think about it, 'Nomen mihi agit Marcus' would more correctly be either 'Marcus does my name' or 'Marcus does the name to me'. This is because, as I said, 'ago' is not copular so the object of the clause cannot be in the nominative case. 'Marcus' can only be nominative, but 'nomen' can be either nominative or accusative. In this case, because there can only be one nominative noun phrase, which is 'Marcus', then 'nomen' must be accusative in order for the clause to be grammatically correct. Therefore, 'Marcus' is the subject (nominative) and 'nomen' is the direct object (accusative), so 'Marcus' must be doing something to 'nomen'.
If you're just starting to learn, this may all go above yoyr head. Don't worry. YouTube 'Latin cases' and you will understand. It's not as scary as it sounds. :)
