Erithace fucum pascit.

Pascit is the 3rd person singular present active indicative of pasco.

So, by itself, it means he/she/it feeds or he/she/it grazes/pastures, depending on context.

A quick breakdown:

• pasc- = the verb stem
• -it = he/she/it in the present tense for this verb type

So even without a separate word for he, she, or it, Latin already gives you that information in the verb ending.

Because fucum is the direct object of pascit, so it is in the accusative singular.

Its dictionary form would be fucus. For a regular second-declension masculine noun, the accusative singular usually ends in -um:

• nominative: fucus
• accusative: fucum

So the ending shows that this is the thing being fed.

As written, Erithace is most naturally read as a vocative singular form, probably from Erithacus.

The vocative is the case used for direct address. In many second-declension nouns ending in -us, the vocative singular changes to -e:

• nominative: Erithacus
• vocative: Erithace

So if that is the intended analysis, Erithace means something like O Erithacus or Erithacus!

The subject is understood from the verb pascit.

In Latin, verbs often contain enough information to make a separate subject pronoun unnecessary. The ending -t tells you the subject is he, she, or it.

So Latin can say simply:

• fucum pascit = he/she/it feeds the fucus

If Erithace is vocative, it is not the subject; it is just the person or creature being addressed.

Because Latin has no articles.

That means Latin does not have separate words exactly equivalent to English the or a/an. Whether you translate a noun with the, a, or with no article at all depends on context.

So fucum could be understood as:

• the fucus
• a fucus

depending on the translation context you were given.

Yes. The word order is perfectly possible Latin.

Latin word order is much more flexible than English word order because the endings show each word’s job in the sentence.

Here the structure is roughly:

• Erithace = direct address
• fucum = object
• pascit = verb

Latin very often puts the verb at the end, so ... fucum pascit is a very normal-looking pattern.

In an English-style punctuation system, yes, if Erithace is a vocative.

So you might punctuate it as:

• Erithace, fucum pascit.

That comma helps show that Erithace is being addressed directly, not acting as the subject.

In Latin, however, punctuation is much less ancient and much less central to the grammar itself, so printed texts may vary.

You usually look up the base form, not the exact form you see in the sentence.

So here you would look up:

• pascit under pasco
• fucum under fucus
• Erithace under Erithacus, if it is a vocative form

This is a very common skill in Latin: identifying what case or verb form you have, and then recovering the dictionary entry from it.
