Dum mater et filia segetem metunt, frater falcem e terra tollit et servat.

Dum here means while. It introduces a time clause:

• Dum mater et filia segetem metunt = While the mother and daughter are harvesting the crop

A very common use of dum is with the present tense to describe something happening at the same time as the main action.

Because with dum meaning while, Latin normally uses the present indicative.

So:

• dum ... metunt = while ... are harvesting

Even if English might sometimes use slightly different wording, Latin regularly keeps the present here for an action going on at the same time.

Because:

• mater = mother
• filia = daughter
• they are joined by et = and
• the verb metunt is plural

So mater et filia form a compound subject: the mother and daughter harvest / are harvesting.

If only one person were doing the action, the verb would be singular.

Metunt is:

• 3rd person plural
• present tense
• active voice
• from meto, metere = to reap, harvest

So it means:

• they harvest
• or, in smoother English here, they are harvesting

Because segetem is the accusative singular form of seges, segetis.

It is in the accusative because it is the direct object of metunt:

• metunt segetem = they harvest the crop

Many third-declension feminine nouns have accusative singular in -em.

Seges, segetis usually means a crop, standing corn, or a field of grain.

In this sentence, segetem metunt means they are harvesting the crop. Depending on context, an English translation might say:

• the crop
• the grain
• the cornfield
  though crop is often the safest basic meaning

Because the sentence is divided into two parts:

• Dum mater et filia segetem metunt = subordinate clause
• frater falcem e terra tollit et servat = main clause

So the meaning is:

• While the mother and daughter are harvesting the crop, the brother picks up the sickle from the ground and keeps it.

The brother is doing a separate action at the same time.

Tollit is:

• 3rd person singular
• present tense
• active voice
• from tollo, tollere = to lift, raise, pick up, remove

So frater ... tollit means:

• the brother lifts
• the brother picks up

Here picks up is the most natural translation.

Because falcem is the direct object of tollit and also understood as the object of servat.

• falcem tollit = he picks up the sickle
• et servat = and keeps it

So one accusative noun, falcem, serves both verbs.

Falcem comes from falx, falcis, a feminine third-declension noun meaning sickle.

Its forms include:

• nominative singular: falx
• accusative singular: falcem

Since it is the object here, Latin uses falcem.

Not necessarily. Servo, servare can mean:

• save
• preserve
• keep
• watch over

In this sentence, servat most naturally means keeps or puts aside for safekeeping, not rescues.

So:

• falcem ... tollit et servat = he picks up the sickle and keeps it / puts it away safely

Because classical Latin has no definite or indefinite article.

So:

• mater can mean mother or the mother
• filia can mean daughter or the daughter
• frater can mean brother or the brother

You decide from context how to translate it into English.

Terra is in the ablative singular after e.

• e terra = out of the ground / from the ground

Prepositions like a/ab, de, e/ex, cum, in (in some meanings) often take the ablative.

Both e and ex mean out of, from.

A basic guideline is:

• e is used before consonants
• ex is used before vowels or h

So e terra is perfectly normal, because terra begins with a consonant.

That said, in actual Latin writing, ex can sometimes appear before consonants too, but e terra is standard and expected.

Because it joins two different pairs of words:

• mater et filia = mother and daughter
• tollit et servat = picks up and keeps

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

Because the verb endings already show the subject clearly:

• metunt = they harvest
• tollit = he/she/it lifts
• servat = he/she/it keeps

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

Because there is no new subject introduced between the verbs:

• frater falcem e terra tollit et servat

So the natural reading is:

• the brother picks up the sickle from the ground and keeps it

The same subject, frater, applies to both verbs.

Latin word order is much more flexible than English word order because endings show grammatical roles.

This sentence could be rearranged in various ways and still mean basically the same thing, as long as the forms stay the same. For example:

• Dum mater et filia segetem metunt, frater falcem e terra tollit et servat.
• Frater, dum mater et filia segetem metunt, falcem e terra tollit et servat.

The original order is natural and clear. Latin often places verbs toward the end, but not always.

Yes. The clause introduced by dum is subordinate:

• Dum mater et filia segetem metunt = subordinate time clause

The main clause is:

• frater falcem e terra tollit et servat

So the whole sentence has the structure:

• While X is happening, Y happens

They are from different declensions:

• mater, matris = mother, 3rd declension
• filia, filiae = daughter, 1st declension
• seges, segetis = crop, 3rd declension
• frater, fratris = brother, 3rd declension
• falx, falcis = sickle, 3rd declension
• terra, terrae = ground, earth, 1st declension

So this sentence is a good example of how Latin mixes nouns from different declensions, and the endings tell you what each noun is doing.

Because nominative singular forms depend on the declension of the noun, not on one universal ending.

• filia is a 1st-declension noun, so its nominative singular ends in -a
• mater is a 3rd-declension noun, so its nominative singular has a different form

Both are nominative here because both are subjects of metunt, even though their endings are different.

Yes. Latin present tense can often be translated either way in English, depending on context:

• they harvest
• they are harvesting

With dum meaning while, English usually sounds more natural with the progressive:

• while the mother and daughter are harvesting the crop

But grammatically, the Latin form itself is simply present tense.
