Ablative of Price and Genitive of Quantity

The price of something is put in the ablative case.

  • He sold the land for money: agrum pecūniā vendidit.
  • Jokes: who wants them for a dinner: logōs rīdiculōs: quis cēnā poscit?

The ablative of price is similar to the ablative of penalty, as it is ultimately an (adverbial) ablative of material, describing the compositional means by which an exchange is achieved.

What you’ll see as often or more often than the ablative of price are similar genitive words indicating indefinite value.

  • It is of great importance to me: mihi magnī interest.
  • That doesn’t matter to me: illud parvī mihi rēfert.
  • The cloak is worthy a great deal to me: amiculum mihi tantī est.
  • I care nothing for this color: istum colōrem nīlī (or nihilī) pendō.

Common words with the genitive of value: magnī, parvī, tantī, quantī, plūris, minōris, nihilī/nīlī, assis, floccī.

(floccī is ‘of a lock of wool.’)

  • I care not a straw: nōn floccī pendō.

The verbs of buying and selling:

  • concilio, conciliāre, conciliāvī, conciliātus: to buy
  • parō, parāre, parāvī, parātus: to buy
  • redimō, redimere, redēmī, redemptus: to buy back
  • vendō, vendere, vendidī, venditus: to sell
  • dō, dāre, dedī, datus: to give, sell

Ablative of Means and Instrument (Basic)

Ablative of Manner, Means and Instrument (p 2/3)


Summary of Use

Allen and Greenough identify three major categories of case usage with the ablative: (1) the ablative proper, (2) the instrumental ablative and (3) the locative ablative

  • The ablative of means, manner and instrument are a collected heading under the (2) instrumental ablative

These uses of the ablative are part of what was once the instrumental case, so “no sharp line can be drawn between them, and indeed the Romans themselves can hardly have thought of any distinction” (AG 408)

The ablative of manner is often distinguished by the use of cum as an initiating preposition


Ablative of Means and Instrument

These will typically appear without a preposition, and qualify an action, not an object

There is no fine line between means and instrument

  • They fought with fists, heels, nails and even teeth: pūgnīs calcibus, unguibus, morsū dēnique certābant.
  • I have resisted with virtue: virtūte passus sum. 
  • I have resisted with force: vī passus sum.
  • I have resisted with the sword: ense passus sum.
  • There is no nation he could not conquer with his authority: nullā gēns est, quam nōn auctoritāte convincat. 

With Verbs and Participles of Filling

Verbs such as pleō, compleō, expleō, referō, and differō take the ablative of means

  • God has filled the world with all good things: Deus donīs omnibus explēvit mundum.
  • Her life was filled and crowded with delights: vīta sua plēna et cōnferta voluptātibus fuit.
  • The Appian forum was crowded with sailors: Forum Appī differtum nautīs erat.

In poetry, may take the genitive instead of the ablative

  • I fill up the banquet with my neighbors: convīvum vīncōrum compleō.
