"You are Marcus."

Translation: Tu es Marcus.

[Tom729640]

Why not 'tu Marcus es'? Verbs usually go at the end of the sentence in Latin.

Can someone explain to me the differences between is, es and est?

[Rae.F]

Latin	English
is	he
es	(you, singular) are
est	(he/she/it) is

conjugation of sum, esse

personal pronouns (nominative)

[jacintha646466]

why did we Marcus not Marce here?

[Rae.F]

Because we need the nominative here, not the vocative.

"Hey, Marcus! You are Marcus."
Marce! Marcus es.

[drickal]

Why is it "quis est Marcus?" but the statement it is "tu es Marcus."? The question is why is it "est" for the question and "es" as a statement.

[Rae.F]

Question vs statement has nothing to do with it. "Es" is the 2nd person singular and "est" is the 3rd person singular.

You are Marcus. Tu es Marcus.
Are you Marcus? Esne tu Marcus?
The -ne turns it into a yes/no question.

He is Marcus. Is est Marcus.
Who is Marcus? Quis est Marcus?

This is the same as it would be in french, except for the pronunciation.

[deveshgupt669339]

Can we not use 'tibi' instead of 'tu'

[Rae.F]

Not in this construction. You're thinking of "Your name is Marcus", which would be "Nomen tibi est Marcus", literally "The name to you is Marcus".

[shruthrh]

Would it be wrong to use the vocative here ?

[Rae.F]

It would be wrong. You're not addressing him, you're stating his name.

Think of the vocative as an exclamation that exists just to the side of the sentence, not technically part of the sentence itself.

Marce, is est Stephanus.
Stephane, is est Marcus.
Marce, tu es Marcus.
Stephane, tu es Stephanus.

[shruthrh]

Ah ok. The use of exclamation clarifies it. Thank you.

Por favor pongámonos de acuerdo. Si escribo Marcus me han calificado mal.
