Puella librum amissum tandem recipit.

Because puella is in the nominative singular, the case normally used for the subject of a finite verb in Latin.

• puella = girl
• nominative singular of a first-declension noun

So puella is the girl, the one doing the action of recipit.

Because librum is the accusative singular form, which marks the direct object.

• liber = nominative singular, book as subject
• librum = accusative singular, book as object

In this sentence, the book is what the girl gets back, so Latin uses the accusative: librum.

Because amissum is describing librum, and adjectives in Latin must agree with the nouns they describe in:

• gender
• number
• case

Here:

• librum = masculine, singular, accusative
• amissum = masculine, singular, accusative

So amissum matches librum exactly. It means lost or mislaid, so librum amissum means the lost book.

It is the perfect passive participle of amitto, amittere.

Literally, it means something like having been lost or lost. But in ordinary translation, it often works just like a simple adjective:

• librum amissum = the lost book

This is very common in Latin: participles often function like adjectives.

Recipit is:

• third person singular
• present tense
• active voice
• indicative mood

It comes from recipio, recipere, meaning get back, recover, receive back, or take back depending on context.

Because it is third person singular, the subject must be he/she/it. Here, since the subject is puella, it means she gets back or she recovers.

Because the ending of the verb already tells you the subject.

In recipit, the ending -it shows that the verb is third person singular: he/she/it. Since puella is present, we know specifically that it is she.

Latin often leaves subject pronouns out unless they are needed for emphasis or contrast.

More or less, yes. The verb contains the prefix re-, which often has the idea of back or again.

So recipere can mean:

• receive back
• get back
• recover
• sometimes take back

In this sentence, the idea is that the girl gets her lost book back, so recovers or gets back is very natural.

Tandem is an adverb meaning:

• at last
• finally
• eventually

It adds the idea that this took some time or happened after waiting. So it modifies the verb recipit:

• Puella librum amissum tandem recipit.
• The girl finally gets back the lost book.

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

So tandem could appear in different positions without changing the basic meaning. Its current position is natural and clear, but Latin often moves words around for emphasis or style.

For example, Latin could also say:

• Puella tandem librum amissum recipit.
• Librum amissum puella tandem recipit.

The core meaning stays the same, though emphasis may shift.

Yes, but not in the same way as in English.

In English, word order is the main way to show who is doing what. In Latin, case endings do most of that work:

• puella = subject
• librum = object

So Latin word order is often used more for:

• emphasis
• rhythm
• style

This sentence ends with the verb recipit, which is a very common Latin pattern.

Latin has no articles like English the or a/an.

So a noun like puella can mean:

• girl
• a girl
• the girl

And librum can mean:

• book
• a book
• the book

Context tells you which is best in translation. In this sentence, English usually wants the girl and the lost book.

Usually lost is better here.

Amissus is the participle of a verb meaning to lose, so it describes something that has been lost. In English, missing can work in some contexts, but lost book is the most straightforward and natural translation here.

• puella is a first-declension noun
• liber is a second-declension noun, and librum is its accusative singular form

So this sentence is also a good example of how different declensions can appear together, each with its own endings.

Latin often prefers compact phrasing. A participle lets Latin express the idea very efficiently:

• librum amissum = the lost book

English can do this too with lost, so the translation is neat. But if needed, the idea could be expanded in English as the book that had been lost.

A common classroom pronunciation would be roughly:

• poo-EL-lah LEE-broom ah-MEES-soom TAHN-dem reh-KEE-pit

If you are using restored classical pronunciation, c in recipit is always hard, like k.

So recipit sounds like reh-kee-pit, not like English receive.
