The Ultimate Guide to the Vocative Case in Latin
Wondering what the vocative case is in Latin? This post tells you everything you need to know, with examples and charts.
The good news is that the vocative case is one of the easiest Latin cases to learn. It only has one use and it is almost always identical to the nominative case in form.
This post will cover
- what the vocative is
- what the forms of the vocative are (with a handy infographic)
- how to use the vocative (with lots of examples)

Vocative Case: The Basics
The vocative case is used for direct address. In other words, if you are speaking directly to someone, any term that you use to refer to them must be in the vocative.
Usually you address someone by their name, but you might also use a term of endearment or an insult. Whatever you call them, you put it in the vocative case in Latin.
Here are some examples in English with nouns in the vocative (vocatives) in bold.
Hey, Dad, help me wash the dishes!
Angela, do you know why the sky is blue?
You idiot! What are you doing?
Children, you know you aren’t supposed to run inside.
Come on, computer, why aren’t you working?
Honey, the house is flooding!
As you can see from these examples, vocatives often appear in commands, questions, and exclamations. This makes sense, because you are most likely to call someone by name if you are angry, curious, or feeling some other emotion.
Another sign to watch out for vocatives is a second person pronoun (“you” or “y’all”). And sometimes the exclamation “Ō” will be included along with the vocative.
You can remember the use of the vocative by thinking about its name. “Vocative” comes from the Latin cāsus vocātīvus “vocative case”, which in turn comes from the verb vocō “call”. So the vocative is literally the “calling” case.
Think about related words in English, like “vocation” (your calling), “evoke” (call out), and even “voice”. This will help you to associate the vocative with direct address.
Forms of the Vocative Case in Latin
The good news is that the vocative case is almost always identical to the nominative case in form. Yay! Less case endings to memorize.
In fact, the vocative only has a different ending in singular masculine nouns and adjectives of the second declension. Specifically, singular masculine nouns and adjectives of the second declension that end in –us!
Here are two quick rules to follow in order to form the vocative case:
- If the nominative of a noun or an adjective ends in –us, remove –us and add –e.
- BUT if the noun is a proper noun (a name) AND the nominative ends in –ius, remove –ius and add –ī.
Here is a graphic for more visual learners.
There are a few exceptions, which I list below. I give first the nominative singular and then the vocative singular.
- fīlius “son” > fīlī
- genius “tutelary deity, genius” > genī
- meus “my” > mī
- Deus “God” > Deus
- Iēsus “Jesus” > Iēsū
I repeat: for all other nouns and adjectives the vocative is equal to the nominative. For this reason, the vocative is not typically included in noun declension paradigms. It simply isn’t necessary!
Examples of the Vocative Case in Latin
Now let’s look at some examples in Latin. Here’s a nice chart showing five 2nd declension Latin nouns in the vocative.
| NOM. | VOC. | MEANING |
|---|---|---|
| Marcus | Marce | proper name |
| dominus | domine | master |
| amīcus | amīce | friend |
| oculus | ocule | eye |
| Tullius | Tullī | proper name |
And here’s a chart showing five 2nd declension Latin adjectives in the vocative.
| NOM. | VOC. | MEANING |
|---|---|---|
| bonus | bone | good |
| laetus | laete | happy |
| eximius | eximie | excellent |
| stultus | stulte | stupid |
| ēgregius | ēgregie | distinguished |
Now that you know what the vocative endings are, it is time to take a look at some full Latin sentences. Vocatives are in bold. Note that I have included vocatives from all declensions, not just second declension.
Vocative adjectives can appear on their own (see stulte below) or modifying a vocative noun (see bona below).
Come with me, son! = Mēcum venī, fīlī!
O good queen, you are wise. = Ō bona rēgīna, sapiēns es.
Don’t touch the wolf, soldiers! = Lupum nōlīte tangere, mīlitēs!
What are you doing, silly? = Quid facis, stulte?
How are you today, Romulus? = Quid agis hodiē, Rōmule?
Mother, why are you silent? = Māter, cūr tacēs?
Final Thoughts on the Vocative
Does everything make more sense now? I hope so. The big takeaways from this post are that the vocative is the case of direct address and that most of the time, the vocative looks like the nominative.
Note also that “vocative” is often abbreviated to “voc.” or even just “V”.
A Final Note For Grammar Nerds
I have presented the case endings of the vocative in accord with the standard rules given in most grammars. But there is actually quite a bit of debate over nouns and adjectives that end in –ius.
When does the vocative end in –ī and when in –ie? The standard explanation, as we saw above, is that proper nouns take –ī (along with fīlius and genius) and that other nouns and all adjectives take –ie.
Things are actually not quite so clear-cut. The time period makes a difference, and even ancient Roman grammarians argued about which form was correct.
If you are interested in exploring this topic in more depth, I recommend the following article by Eleanor Dickey, Professor of Classics at the University of Reading.

Thank you. I love good explanations. I wonder if there is an error…
“There are a few exceptions, which I list below. I give first the nominative singular and then the ablative singular.”
This had me running to an explanation of the ablative….
Oops, you are right! I will correct this. I’m glad you liked the explanations, and this is a reminder that I need to write a post about the ablative!
Livia,
This is grand. I taught English grammar and writing and ancient history to 12 and 13 year olds. Most grammar books are dull and in their lack of sparkle. Well stated points get lost. This has sparkle and wonderful clarity. I tumbled to the fact that my 12 years old boys would eat up Homer if I read the Iliad to them and they were amazing in diagramming and parsing each line. ( not their favorite part of Homer. I was introducing them to Latin ( unheard of in California) and this would have been great!
Hi Nancy, I am so glad that you think this post has sparkle! I try to make my explanations interesting as well as informative. That’s great that you were reading the Iliad to your students and introducing them to Latin. Not everyone has the opportunity to experience Latin so young!
I love this, thank you! I might have missed them somewhere, but I think there are no examples of sentences using the vocative adjective case and I’m a confused on when that would be used. But happy I know how to spot it!
Hi Meggan, I am so glad you loved the post! Oops, you are right about there being no examples with an adjective in the vocative – I have fixed this now 🙂
Thank you for covering 2nd declension adjectives in the vocative. I can’t find it in my texts or Allen and Greenough.
You are welcome, Ralph! I try to make my posts as comprehensive as possible.
Allen and Greenough do comment briefly on the vocative of adjectives at §110a, but the section is so brief as to be unhelpful. That’s why I have gone into more depth here 🙂
Thank you for the clear explanations. Could you please say more about the position of vocative forms in the sentence? I was taught that a vocative form is never the first word. Therefore, as you write, Ō bona rēgīna, sapiēns es, but you also have Māter, cūr tacēs?
Hi David, excellent question! I was never taught this, but I did some digging and Bennett’s Latin Grammar does say at §350.3 that the vocative “usually follows one or more words.” This is not a hard-cut rule, though, since my quick search of the Latin literary corpus turned up examples of sentences beginning with a vocative. (E.g. Plautus Truculentus 577: “Noster Cyame, quid agis?”)
Allen and Greenough’s, which is my go-to Latin grammar, says nothing about the placement of the vocative within a sentence. But the first example sentence is Livy ii.10, which puts the vocative first: “Tiberīne pater, tē, sāncte, precor!” Ultimately, I would conclude that the vocative is less likely to be the first word in a sentence, but it isn’t impossible.
Unfortunately, my language skills are limited to English and I am battling to understand what case the latin phrase for “Friends! Romans! Countrymen! Lend me your ears” is. When I read the information I think it is Vocative because it is in my mind a direct address or a command. However, my initial thought was it could be Nominative but Vocative seems to fit better. Am I right or wrong? Any advice appreciated.
Hi Brian, the words in “Friends! Romans! Countrymen!” would all be in the vocative case. This is because, as you intuited, Marc Antony is here directly addressing his fellow Romans. We use the nominative for the subject of a sentence, so for instance if you said “My friends lend me their ears”, “friends” would be in the nominative.
I hope this helps! 🙂
