Questions & Answers about In sententia “Puella canem vocat” nomen “puella” in casu nominativo est, “canem” autem in casu accusativo.
What do nominative and accusative mean?
They are cases, meaning different forms of a noun that show its job in the sentence.
- Nominative = usually the subject, the person or thing doing the action.
- Accusative = usually the direct object, the person or thing receiving the action.
In Puella canem vocat:
- puella is nominative because the girl is doing the calling.
- canem is accusative because the dog is being called.
Why is puella in the nominative case?
Because puella is the subject of vocat. The girl is the one who performs the action.
So in Puella canem vocat, the structure is:
- puella = the girl = subject
- vocat = calls
- canem = the dog = direct object
Since Latin marks the subject with the nominative, puella is nominative.
Why is canem in the accusative case?
Because canem is the direct object of vocat. It is the one receiving the action.
The sentence means that the girl is calling the dog, so the dog must be in the accusative.
For the noun canis:
- nominative singular: canis
- accusative singular: canem
So Latin changes the form to show the noun’s role.
How can I tell from the endings which case these nouns are in?
The endings are the clue.
For puella, a first-declension noun:
- nominative singular: puella
- accusative singular: puellam
So puella is nominative, not accusative.
For canis, a third-declension noun:
- nominative singular: canis
- accusative singular: canem
So canem is accusative, not nominative.
This is one of the most important things in Latin: endings matter more than word order.
If Latin endings show the roles, does the word order matter much here?
Not as much as in English.
In English, The girl calls the dog and The dog calls the girl mean different things mainly because of word order.
In Latin, the endings already show who is doing what. So these can all mean basically the same thing:
- Puella canem vocat
- Canem puella vocat
- Vocat puella canem
Because puella is still nominative and canem is still accusative, the girl is still the subject and the dog is still the object.
That said, word order in Latin can still affect emphasis or style.
What does vocat tell us exactly?
Vocat is a verb form meaning calls or is calling.
It is:
- third person singular
- present tense
- from the verb vocare = to call
It is third person singular because the subject, puella, is singular: one girl.
So puella vocat = the girl calls.
Why is there no word for the or a in Puella canem vocat?
Because Latin does not have articles like English the and a/an.
So:
- puella can mean girl, a girl, or the girl
- canem can mean dog, a dog, or the dog
The context tells you which English translation is best.
What does autem mean in the explanation sentence?
Autem means something like:
- however
- but
- on the other hand
In the sentence
“Puella” in casu nominativo est, “canem” autem in casu accusativo
it contrasts the two nouns:
- puella is nominative,
- canem, however, is accusative.
A useful thing to know is that autem often comes second in its clause.
Why does the explanation say in casu nominativo and in casu accusativo?
That phrase means in the nominative case and in the accusative case.
- casu is a form of casus meaning case
- nominativo and accusativo agree with casu
The preposition in here takes the ablative, which is why you see:
- in casu nominativo
- in casu accusativo
So this is just a standard Latin way of saying what case something is in.
Why does the sentence use nomen? Aren’t puella and canem just words?
Yes, they are words, but more specifically they are nouns.
Nomen in Latin can mean name or noun, depending on context. Here it means noun.
So the explanation is saying:
- the noun puella is in the nominative case,
- the noun canem is in the accusative case.
Could canem ever be the subject of the sentence?
Not in this form.
Because canem is accusative singular, it marks the dog as the direct object, not the subject.
If the dog were the subject, you would normally expect canis instead:
- Canis puellam vocat = The dog calls the girl
So the form canem tells you that the dog is receiving the action, not doing it.
