Puella rosas et violas in horto legit et matri ostendit.

They are accusative plural forms. In Latin, the accusative case is commonly used for the direct object of a verb.

So here:

• rosas = roses
• violas = violets

These are the things the girl is picking. Both nouns are first-declension feminine nouns, so their accusative plural ends in -as.

Because it is joining two different pairs:

• rosas et violas = roses and violets
• legit et ostendit = picks and shows

So the first et connects two nouns, and the second et connects two verbs.

After in, Latin uses different cases depending on the meaning:

• in + ablative = in / on a place, showing location
• in + accusative = into / onto a place, showing motion toward

So:

• in horto = in the garden
• in hortum would mean into the garden

Here the girl is located in the garden while doing the action, so Latin uses horto, the ablative singular of hortus.

Because matri is in the dative singular, the case often used for an indirect object.

With a verb like ostendit (shows), Latin commonly uses:

• the thing shown in the accusative
• the person it is shown to in the dative

So matri means to mother or, in natural English here, to her mother.

Also, mater is a third-declension noun, so its dative singular is matri, not something like matrae.

Latin often leaves out a word when it is easy to understand from context. After legit, we already have rosas et violas, so after ostendit the object is understood.

In other words, the sentence means:

• the girl picks roses and violets
• and shows them to her mother

Latin does not need to repeat the object if it is obvious.

Classical Latin has no articles. It has no separate words that exactly equal English the or a/an.

So puella can mean:

• the girl
• a girl

Context tells you which is best in translation. The same is true for horto, rosas, violas, and matri.

Latin often leaves out possessive words like my, your, or her when the meaning is already clear.

So matri by itself can naturally be understood as to her mother in this context. If Latin wanted to say it more explicitly, it could use matri suae.

In this sentence, they are understood as third-person singular active indicative verbs, agreeing with puella.

So the basic idea is:

• legit = she picks / gathers
• ostendit = she shows

A learner should notice that Latin verb endings often tell you who is doing the action, so Latin does not need a separate subject pronoun like she.

Because Latin words often have more than one meaning, and context decides which one fits.

The verb lego can mean things like:

• pick / gather
• choose
• read

Here the objects are roses and violets, and the setting is in the garden, so picks or gathers is the natural meaning.

Because Latin relies much more on word endings than on word order.

In English, we usually need a fairly fixed order like:

• subject + verb + object

But in Latin, the endings already show which word is the subject, direct object, indirect object, and so on. That gives Latin much more freedom in arrangement.

This sentence uses a very common Latin pattern in which important verbs come late:

• Puella = subject first
• rosas et violas = objects next
• in horto = place
• legit et matri ostendit = verbs toward the end

So the order may feel unusual to an English speaker, but it is normal Latin.
