Mater filiam ad horreum ducit, ut frumentum videat.

Because mater is in the nominative case, which is the case normally used for the subject in Latin.

• mater = mother (nominative singular)
• filiam = daughter (accusative singular)

So the sentence means that the mother is doing the action of leading.

Because filiam is in the accusative case, which is commonly used for the direct object.

Here, the daughter is the person being led, so she is the direct object of ducit.

Compare:

• filia = daughter as subject
• filiam = daughter as direct object

So:

• filia ducit = the daughter leads
• mater filiam ducit = the mother leads the daughter

Ad usually means to, toward, or up to when it shows motion.

The preposition ad takes the accusative case, so horreum is accusative.

• horreum = granary, storehouse
• ad horreum = to the granary

So the phrase tells you where the mother is leading the daughter.

Ducit is the 3rd person singular present active indicative of ducere, meaning to lead.

Breaking it down:

• duc- = verb stem
• -it = he/she/it in the present tense for this conjugation

So ducit means:

• he leads
• she leads
• it leads

In this sentence, the subject is mater, so it means she leads.

Here ut introduces a purpose clause. A purpose clause explains why something is done.

So:

• Mater filiam ad horreum ducit = The mother leads the daughter to the granary
• ut frumentum videat = so that she may see the grain

Together, the sentence gives both the action and its purpose.

A very common translation of this kind of ut is:

• so that
• in order that

Because after ut in a purpose clause, Latin uses the subjunctive mood, not the indicative.

So:

• videt = she sees / he sees (indicative: plain statement)
• videat = may see / might see (subjunctive, used here for purpose)

That is why Latin says:

• ut ... videat = so that ... may see

This is one of the most important patterns in Latin grammar:

• ut
  • subjunctive = often a purpose clause

The most natural understanding is that the daughter is the one who is meant to see the grain.

Why? Because the sentence says:

• The mother leads the daughter to the granary
• so that she may see the grain

The person being led somewhere for a purpose is usually the one expected to do the seeing.

Also, Latin often leaves the subject of the subordinate verb unstated when it can be understood from context. So videat does not explicitly say she, but context makes it clear.

Frumentum is in the accusative case because it is the direct object of videat.

It is the thing being seen.

So in the clause:

• frumentum videat

the meaning is:

• she may see the grain

Frumentum often means grain, corn in the older British sense, or more generally food grain.

In Roman contexts it usually refers to grain as an important stored crop or food supply.

So in this sentence, the mother leads the daughter to the granary so that she can see the stored grain.

Because Latin word order is more flexible than English word order. Latin relies much more on word endings to show each word’s role.

English depends heavily on position:

• The mother leads the daughter is different from
• The daughter leads the mother

But in Latin, the endings already tell you who is subject and who is object:

• mater = subject
• filiam = object

So Latin can place words in different orders without changing the basic meaning. The order here is perfectly normal and clear.

Yes, often it could. For example, Latin could rearrange parts of the sentence and still keep the same basic meaning because the endings show the grammar.

For instance, forms like these could still be understood:

• Mater ad horreum filiam ducit, ut frumentum videat.
• Filiam mater ad horreum ducit, ut frumentum videat.

The emphasis may shift slightly depending on the order, but the core meaning remains the same.

The ending -eat here marks 3rd person singular present subjunctive active of videre.

So videat means:

• he may see
• she may see
• it may see

If it were plural, you would expect videant:

• videant = they may see

Since the verb is singular, the understood subject is one person, not several.

A learner often wants to connect the forms in the sentence to the forms found in a dictionary. Here they are:

• mater → mater, matris = mother
• filiam → filia, filiae = daughter
• horreum → horreum, horrei = granary
• ducit → duco, ducere, duxi, ductum = lead
• frumentum → frumentum, frumenti = grain
• videat → video, videre, vidi, visum = see
• ad = to, toward
• ut = so that, in order that

Seeing how sentence forms connect to dictionary forms is an important reading skill in Latin.
