Serva onus grave ad horreum portat, et pater ei auxilium fert.

Serva is in the nominative singular, which is the case normally used for the subject of a verb.

• serva = the female slave / servant girl
• portat = carries

So Serva ... portat means The slave girl carries ...

A learner may notice that serva ends in -a, which is a very common nominative singular ending for first-declension nouns.

Because grave has to agree with onus.

• onus means burden / load
• It is a neuter noun
• Here it is accusative singular, because it is the direct object of portat

The adjective gravis, grave means heavy. Its neuter accusative singular form is grave.

So:

• onus = neuter accusative singular
• grave = neuter accusative singular

They match, as Latin adjectives normally do in gender, number, and case.

Because it is the direct object of portat.

The verb porto means I carry. What is being carried? the burden. That makes onus the direct object, so Latin puts it in the accusative case.

Structure:

• Serva = subject
• onus grave = direct object
• portat = verb

Ad means to / toward when there is motion in the direction of a place.

Since the sentence involves carrying something to the storehouse, Latin uses:

• ad
  • accusative

So:

• ad horreum = to the storehouse

This is different from a phrase that would mean in the storehouse, which would use a different construction.

Because ad takes the accusative case.

The noun is horreum (storehouse, neuter, second declension). Its accusative singular form is also horreum.

So:

• nominative singular: horreum
• accusative singular: horreum

For many neuter second-declension nouns, the nominative and accusative singular look the same.

Ei is the dative singular form of the pronoun is, ea, id.

In this sentence, it means to her.

Why dative? Because with auxilium fert, the person receiving the help is put in the dative:

• pater ei auxilium fert = the father brings help to her

So:

• ei = to her / for her

The form ei can also mean to him or to it in other contexts; the surrounding sentence tells you which is intended.

Literally, auxilium fert means brings help.

• auxilium = help
• fert = carries / brings

But in natural English, we often translate this more smoothly as helps.

This is a very common Latin way of expressing the idea:

• alicui auxilium ferre = to bring help to someone, therefore to help someone

So the Latin is slightly more concrete than the English translation.

Because pater is the subject of the second clause.

In et pater ei auxilium fert:

• pater = subject
• ei = indirect object
• auxilium = direct object
• fert = verb

Since pater is doing the action, it must be in the nominative.

Because it is the direct object of fert.

The father brings what? help. Therefore auxilium is in the accusative.

This gives the pattern:

• pater = nominative subject
• ei = dative indirect object
• auxilium = accusative direct object
• fert = verb

Yes, both verbs can involve the idea of carrying or bearing, but they are not identical.

• portat often means carries, transports
• fert (from fero) is a very common and somewhat broader verb meaning bears, carries, brings

In this sentence:

• serva ... portat works well for physically carrying a heavy load
• pater ei auxilium fert is a standard idiom meaning the father brings her help

So the two verbs are related in meaning, but fert is especially natural in the expression auxilium ferre.

Latin word order is much more flexible than English word order because Latin shows grammatical relationships with case endings, not mainly with position.

English depends heavily on order:

• The father helps her

Latin can move words around more freely because the endings show the function of each word.

Here the sentence is fairly straightforward, but it still feels more Latin than English:

• Serva onus grave ad horreum portat
• et pater ei auxilium fert

A common Latin tendency is to place the verb near the end, though this is not a strict rule.

Because Latin has no articles.

English uses:

• the slave girl
• a heavy load
• the storehouse
• the father

Latin simply says:

• serva
• onus grave
• horreum
• pater

Whether you translate these as the, a, or sometimes leave them more indefinite depends on the context. Latin usually lets the reader infer that from the situation.

It can be understood either way depending on context.

The basic word serva is the feminine form related to servus. In many classical contexts it most literally means female slave, but in some teaching materials or looser translations it may be rendered as servant girl.

So if the meaning has already been given to the learner, that translation choice may reflect the tone of the course rather than a grammatical difference.

The sentence has two main clauses joined by et (and):

1. Serva onus grave ad horreum portat
2. et pater ei auxilium fert

Each clause has its own subject and verb:

• first clause: serva ... portat
• second clause: pater ... fert

The second clause also refers back to the slave girl with ei (to her). So the father is helping the same person who is carrying the heavy load.
