Si amica tua lacrimat et suspirat, noli statim discedere, sed apud eam mane.

Si means if.

In this sentence, Si amica tua lacrimat et suspirat = If your girlfriend/female friend is crying and sighing.

The if-clause often comes first in Latin, just as it often does in English, but it does not have to. Latin word order is more flexible. The speaker puts it first here because it sets up the situation before giving the command.

Yes. Amica means female friend (and depending on context, sometimes girlfriend), and tua means your.

So:

• amica = female friend
• tua = your

Together: amica tua = your female friend

Both words are in the nominative singular feminine, because amica is the subject of lacrimat and suspirat, and tua agrees with it.

Yes. Both amica tua and tua amica are possible.

Latin often allows more than one word order. The difference is usually one of emphasis or style, not basic meaning.

• amica tua = your female friend
• tua amica = your female friend

In many simple sentences, either order is fine.

Both are 3rd person singular present active indicative verbs.

• lacrimat = she is crying / she cries
• suspirat = she is sighing / she sighs

Because the subject is amica tua, these forms are understood as she.

Latin often uses the simple present where English might use either:

• cries / sighs
• or is crying / is sighing

So here the natural sense is probably is crying and sighing.

Because Latin usually does not need an expressed subject pronoun.

The ending -t in lacrimat and suspirat already tells you the verb is 3rd person singular: he/she/it.

Since amica tua is already named, Latin does not need to add ea for she.

This is a very common Latin way to make a negative command.

• noli = be unwilling, from nolo
• followed by an infinitive

So:

• noli discedere = do not leave

Latin often uses:

• noli + infinitive for don’t ... when speaking to one person
• nolite + infinitive for don’t ... when speaking to more than one person

Using non with an imperative is generally not the normal classical way to give a negative command.

Noli is the singular imperative of nolo, nolle, nolui, which means to be unwilling.

So literally:

• noli discedere = be unwilling to leave

But in normal English we translate it as:

• do not leave
• don’t leave

It is an idiomatic Latin construction.

Because after noli, Latin uses the infinitive.

So:

• noli discedere = don’t leave
• literally, be unwilling to leave

This is just the standard pattern:

• noli + infinitive = negative command to one person
• nolite + infinitive = negative command to more than one person

Statim means immediately, at once, or right away.

So:

• noli statim discedere = do not leave at once / don’t leave immediately

It modifies discedere.

The idea is not merely don’t leave, but specifically don’t leave right away.

Discedere means to go away, to depart, or to leave.

In this sentence, it means leaving the person who is upset.

So the sense is:

• don’t go off
• don’t walk away
• don’t leave

Sed means but.

It contrasts the two commands:

• noli statim discedere = do not leave immediately
• sed apud eam mane = but stay with her

So Latin is setting up a clear contrast:

• not this
• but that

Apud eam means with her, by her, or at her side.

The preposition apud takes the accusative and often suggests being in the presence of, near, or at the place/person of someone.

So:

• apud eam mane = stay with her / remain by her side

Why not cum ea?

• cum ea also means with her, but often stresses together with
• apud eam can suggest staying near her / in her presence

Here apud eam fits the emotional situation well: don’t leave; stay by her.

Because apud takes the accusative case.

The pronoun ea, id means she / her / it, but its form changes by case.

Here we need the accusative singular feminine:

• nominative: ea = she
• accusative: eam = her

So:

• apud eam = with her / near her

Mane is the singular imperative of maneo, manere, meaning remain or stay.

So:

• mane = stay!

This matches noli, which is also singular. The speaker is talking to one person.

If the command were to more than one person, it would be:

• manete = stay! (plural)

They are different words, even though they are spelled the same way when macrons are not shown.

• manē (with a long final vowel) = stay! from maneo
• mane = in the morning

In texts without macrons, you have to tell from context which one it is. Here it is clearly the verb:

• sed apud eam mane = but stay with her

not

• but with her in the morning

Because both imperative forms are singular:

• noli = singular
• mane = singular

So the speaker is telling one person what to do.

If the speaker were addressing several people, Latin would say:

• nolite statim discedere, sed apud eam manete

Yes. It shows two very common command patterns:

1. Negative command
   noli + infinitive

   • noli discedere = don’t leave

2. Positive command
   imperative of the verb

   • mane = stay

So the sentence gives a nice contrast:

• don’t leave
• but stay

That is a very natural and important Latin pattern to learn.
