Exercitia II — The Frame

One sentence, one noun, five cases. The idea is to have a single mental sentence you can drop any noun into and hear whether a form sounds right, rather than reciting a paradigm table cold. Say the Latin, then the word-order English underneath it, which is deliberately ugly — it maps slot to slot rather than reading well.

The frame, in slot order:

nom · gen · acc · dat · cum + abl · verb

The X · the X's · X · to the X · with the X · gives

Nothing about the frame is idiomatic Latin. It's scaffolding, and it earns its place by making the syncretisms audible: where two slots come out identical, you hear it in your own mouth instead of reading it in a footnote.

First declension

puella, puellae (f.) — girl

Puella puellae puellam puellae cum puellā dat. The girl the girl's girl to the girl with the girl gives.

Puellae puellārum puellās puellīs cum puellīs dant. The girls the girls' girls to the girls with the girls give.

What the singular exposes

Puellae lands twice — genitive and dative — and in the plural puellīs lands twice for dative and ablative. Two of the five slots are doing double duty. Nothing but position and sense separates them.

fēmina, fēminae (f.) — woman

Fēmina fēminae fēminam fēminae cum fēminā dat. The woman the woman's woman to the woman with the woman gives.

Fēminae fēminārum fēminās fēminīs cum fēminīs dant. The women the women's women to the women with the women give.

Second declension

puer, puerī (m.) — boy

Puer puerī puerum puerō cum puerō dat. The boy the boy's boy to the boy with the boy gives.

Puerī puerōrum puerōs puerīs cum puerīs dant. The boys the boys' boys to the boys with the boys give.

What this one exposes

Puerō twice in the singular (dative and ablative), puerīs twice in the plural. And puerī is the notorious one: nominative plural in the second sentence, genitive singular in the first. Same four letters, three jobs across the pair.

dominus, dominī (m.) — master

Dominus dominī dominum dominō cum dominō dat. The master the master's master to the master with the master gives.

Dominī dominōrum dominōs dominīs cum dominīs dant. The masters the masters' masters to the masters with the masters give.

vir, virī (m.) — man

Vir virī virum virō cum virō dat. The man the man's man to the man with the man gives.

Virī virōrum virōs virīs cum virīs dant. The men the men's men to the men with the men give.

Aside — virum turns up as the genitive plural in verse and older Latin, where you'd expect virōrum. Vergil opens the Aeneid with arma virumque canō, which is accusative singular, but a few lines on you'll meet the short genitive plural doing duty for the metre. Classical prose keeps virōrum.

oppidum, oppidī (n.) — town

Oppidum oppidī oppidum oppidō cum oppidō dat. The town the town's town to the town with the town gives.

Oppida oppidōrum oppida oppidīs cum oppidīs dant. The towns the towns' towns to the towns with the towns give.

Where the frame breaks, usefully

The neuter rule bites: nominative and accusative are identical in both numbers, so the frame stops telling you who is giving and who is being given. That's the lesson rather than a flaw — with neuters you are reading word order and sense, not endings. Hold onto the discomfort.

Third declension

The nominative is unpredictable and the genitive singular reveals the stem, so each noun below is listed with both. The frame is especially worth running here, because third-declension forms don't rhyme with anything you already know.

mīles, mīlitis (m.) — soldier

Mīles mīlitis mīlitem mīlitī cum mīlite dat. The soldier the soldier's soldier to the soldier with the soldier gives.

Mīlitēs mīlitum mīlitēs mīlitibus cum mīlitibus dant. The soldiers the soldiers' soldiers to the soldiers with the soldiers give.

What this one exposes

In the plural, nominative and accusative are both mīlitēs — the neuter problem arriving in a masculine noun. Dative and ablative plural are both mīlitibus, as they are throughout the third declension. Only the singular keeps all five slots distinct.

māter, mātris (f.) — mother

Māter mātris mātrem mātrī cum mātre dat. The mother the mother's mother to the mother with the mother gives.

Mātrēs mātrum mātrēs mātribus cum mātribus dant. The mothers the mothers' mothers to the mothers with the mothers give.

rēx, rēgis (m.) — king

Rēx rēgis rēgem rēgī cum rēge dat. The king the king's king to the king with the king gives.

Rēgēs rēgum rēgēs rēgibus cum rēgibus dant. The kings the kings' kings to the kings with the kings give.

flūmen, flūminis (n.) — river

Flūmen flūminis flūmen flūminī cum flūmine dat. The river the river's river to the river with the river gives.

Flūmina flūminum flūmina flūminibus cum flūminibus dant. The rivers the rivers' rivers to the rivers with the rivers give.

Neuter again

Nominative and accusative identical in both numbers, plural in -a — the same rule as oppidum, wearing third-declension clothes. Two declensions, one neuter law.

cīvis, cīvis (m./f.) — citizen

Cīvis cīvis cīvem cīvī cum cīve dat. The citizen the citizen's citizen to the citizen with the citizen gives.

Cīvēs cīvium cīvēs cīvibus cum cīvibus dant. The citizens the citizens' citizens to the citizens with the citizens give.

The i-stem tell

Cīvium, not cīvum — the genitive plural in -ium marks this as an i-stem, a sub-family of the third declension. The singular nominative and genitive are also identical here, which the frame makes obvious in the first two slots. Compare mīlitum above and the difference stands out.

Fourth declension

quercus, quercūs (f.) — oak

Quercus quercūs quercum quercuī cum quercū dat. The oak the oak's oak to the oak with the oak gives.

Quercūs quercuum quercūs quercibus cum quercibus dant. The oaks the oaks' oaks to the oaks with the oaks give.

Why this noun is worth the trouble

Quercus is feminine despite the -us ending, and it looks second-declension in the nominative singular until the genitive gives it away — quercūs, not quercī. The frame is doing real work here: the same shape quercūs covers genitive singular, nominative plural and accusative plural, three slots on one form. Its small club of fellow feminines includes manus (hand) and domus (house).

exercitus, exercitūs (m.) — army

Exercitus exercitūs exercitum exercituī cum exercitū dat. The army the army's army to the army with the army gives.

Exercitūs exercituum exercitūs exercitibus cum exercitibus dant. The armies the armies' armies to the armies with the armies give.

Fifth declension

diēs, diēī (m./f.) — day

Diēs diēī diem diēī cum diē dat. The day the day's day to the day with the day gives.

Diēs diērum diēs diēbus cum diēbus dant. The days the days' days to the days with the days give.

What this one exposes

Genitive and dative singular are both diēī, echoing the first declension's puellae trick. In the plural, nominative and accusative are both diēs — and so is the nominative singular, so that one form covers three slots across the pair.

Running the drill

Say the Latin aloud first, then the word-order English, then the Latin again without looking. The second Latin pass is where it sticks.

When a new noun turns up in reading, put it through the frame before doing anything else with it. If you can't produce all five singular slots, the dictionary entry hasn't landed yet — and the genitive is usually the one missing, because it's the one that tells you which declension you're in.

Two habits worth building on top. Swap the verb: dat becomes dabat (was giving), dedit (gave), dabit (will give), and the frame doubles as tense practice with the noun forms held steady. And bolt an adjective onto one slot — puer magnī puerī parvum puerum bonō puerō cum fortī puerō dat — which forces the three-way agreement rule (Vol. III) through five different case environments in one breath.

Aside — the frame is nonsense on purpose, and it should stay nonsense. The moment you start improving it into a sentence that means something, it becomes a thing to admire rather than a tool to use, and the drill quietly turns into a project.
