In suburbio nostro multi textores et fullones habitant.

Because in takes different cases depending on its meaning:

• in + ablative = in / on / at a place, with no motion
• in + accusative = into / onto a place, with motion toward it

Here the sentence means that the people live in the suburb, not that they are going into it, so Latin uses the ablative: in suburbio.

It is ablative singular.

You can tell this because:

• suburbium is a neuter noun
• after in meaning location, it goes into the ablative
• the ablative singular of suburbium is suburbio
• nostro matches it in case, number, and gender

So suburbio nostro means in our suburb.

Because nostro has to agree with suburbio.

Latin adjectives must match the noun they describe in:

• gender
• number
• case

Here:

• suburbio = neuter, singular, ablative
• so noster becomes nostro = neuter, singular, ablative

That is why Latin says suburbio nostro, not suburbio noster or suburbio nostrum.

Because multi is describing the subject of the sentence, so it must be nominative plural.

The subject is multi textores et fullones = many weavers and fullers.

• multi = masculine nominative plural
• textores = masculine nominative plural
• fullones = masculine nominative plural

So they all match.

It is not multos, because multos would be accusative plural, used for a direct object, not a subject.

It is not multae, because that is feminine plural.

It naturally applies to both nouns.

So multi textores et fullones means many weavers and fullers, not just many weavers and fullers in general with only the first noun modified.

In Latin, one adjective can modify two coordinated nouns if the meaning is clear, especially when they are the same gender and number.

They are both nominative plural forms, because they are part of the subject.

Their singular forms are:

• textor = weaver
• fullo = fuller

Their plural forms here are:

• textores = weavers
• fullones = fullers

Both are third-declension nouns.

Habitant is the verb and means they live or they dwell.

The ending -nt shows that it is:

• third person
• plural
• present tense

It matches the plural subject multi textores et fullones.

So:

• habitat = he/she/it lives
• habitant = they live

Latin word order is much more flexible than English word order.

Putting the verb at the end is very common in Latin, especially in straightforward narrative or descriptive sentences. So:

• In suburbio nostro multi textores et fullones habitant
• literally, In our suburb many weavers and fullers live

In English, that sounds marked or poetic, but in Latin it is perfectly normal.

Yes. Because Latin uses endings to show grammatical relationships, the word order can change without changing the basic meaning.

For example, Latin could also say:

• Multi textores et fullones in suburbio nostro habitant
• Habitant in suburbio nostro multi textores et fullones

These all mean roughly the same thing, though the emphasis may shift a little.

The given order begins with in suburbio nostro, which puts the setting first: in our suburb...

Here it is a possessive adjective.

It describes suburbio and means our:

• suburbio nostro = our suburb / in our suburb

It is not standing alone like a pronoun. If it were being used by itself, it could mean something like ours, but that is not what is happening here.

Yes. English suburb ultimately comes from Latin suburbium.

That can help you remember the meaning:

• suburbium = suburb, area outside or near a city
• in suburbio nostro = in our suburb

So this is a nice example of a Latin word that has a clear English descendant.
