Grammar introduced in Cap. XXIX

1. ut + subj. — full inventory (the chapter's GRAMMATICA LATINA codifies this):

   type	trigger	negative
   command/desire	imperō, ōrō, moneō, cūrō ut...	nē
   purpose	(verb of action) ut...	nē
   result	tam, tantus, tālis, ita ... ut...	ut nōn

   Same forms; the meaning depends on context. The chapter contrasts:

   • Dāvus clāmat, ut puerum excitet. = purpose ("in order to wake")
   • Dāvus ita clāmat ut puerum excitet. = result ("so loudly that he wakes")
   • Syra tacet nē puellam excitet. = negative purpose
   • Syra tam quiēta est ut puellam nōn excitet. = negative result

2. cum + subjunctive (cum-circumstantial / cum-causal) — replacing earlier cum + indic. = "when". Now cum + subj. = "when, since, although":

   • Cum gubernātor pallidum videat... "Since the helmsman sees..."
   • Cum Arīōn ex Italiā in Graeciam nāvigāret... "When Arion was sailing..."
   • Cum sēsē nimis fēlīcem esse cēnsēret... "Since he thought himself too fortunate..."

   Tense follows sequence: present main → pres. subj.; past main → impf. subj.

3. Genitive of price/value with aestimāre, esse: magnī aestimat (values highly), parvī aestimat (values little), plūris aestimat (values more), māiōris pretiī est (is of greater value).

4. Verbs taking dative (this chapter consolidates the list): invidēre, parcere, suādēre, persuādēre, permittere, crēdere, appropinquāre, oboedīre, servīre, prōdesse, nocēre, impendēre. Pecūniam nautīs dat (dat of indir. obj. as before), but invidet hominī dīvitī (dat. with verb).

5. Partitive genitive in expressions like nēmō nostrum, nēmō vestrum: "none of us / none of you (pl.)". Also quisquam nostrum.

6. quisquam, quemquam (anyone, after negative): nē quemquam ante mortem beātum dīcere! "Don't call anyone happy before death!"

7. 5th declension spēs spēī f. (joining rēs, diēs from earlier): nom. spēs, gen./dat. speī, acc. spem, abl. spē; pl. spēs, spērum, spēbus.

8. More perfect stems consolidated: vehere → vēxisse, pōnere → posuisse, āmittere → āmīsisse, allicere → allēxisse, ēripere → ēripuisse, secāre → secuisse, suādēre → suāsisse, dēsilīre → dēsiluisse, canere → cecinisse, crēdere → crēdidisse, cōnfitērī → cōnfessum esse, lābī → lāpsum esse, parcere → pepercisse (reduplicated).

9. Idiom iactūram facere reī (gen.) = "to make a sacrifice of a thing, to throw it away".

Common error patterns

• Confusing purpose vs. result ut-clauses: both look the same; trigger word in main clause distinguishes them. tam, tantus, ita, tālis → result. No such trigger → purpose.
• Negative ut nōn vs. nē: Sōl ita lūcēbat ut pāstor in sōle nōn ambulāret — RESULT, so ut nōn is correct. Pāstor umbram petīvit nē in sōle ambulāret — PURPOSE, so nē.
• cum + indic. vs. cum + subj.: in narrative meaning "when, since", classical Latin prefers subjunctive. Student may default to indicative — push them toward subj. when cum introduces a circumstance/cause.
• Dative-taking verbs given an accusative: invideō hominem dīvitem — wrong; invideō hominī dīvitī. Same trap with parcere, persuādēre, oboedīre, nocēre.
• spēs declension: students give acc. spem but stumble on gen. speī (long ē because consonant precedes... actually short ĕī here since consonant p precedes — many say spēī incorrectly long). The textbook writes speī.
• Perfect of parcere: pepercī (reduplicated). Don't say parsī.
• Perfect of canere: cecinī (reduplicated). Don't say canuī.
• Genitive of value with aestimāre: multum aestimō — should be magnī aestimō (gen. of price).
• quisquam in positive sentence: should be aliquis. Quisquam is for negatives, questions, conditions.
• fidēs -ium (lyre, pl.) vs. fidēs -eī (faith, sg.): same nom. sg. but totally different declensions.

Exercise menu

1. Identify ut-clause type: read a sentence aloud, ask purpose vs. result. "Tantus erat strepitus ut nēmō dormīre posset." → result.
2. Form impf subj 3sg recall (still drilling, since now needed in cum clauses): "Impf subj 3sg of vidēre?" → vidēret. "Of cōnārī?" → cōnārētur.
3. PENSVM A blank, choosing tense by sequence: "Magister tam pulchrē scrībit ut Sextus eum laud___ (pres)." → laudet. "Magister tam pulchrē scrīpsit ut Sextus eum laud___ (impf)." → laudāret.
4. Negative ut-clause: "Sōl ita lūcēbat ut pāstor in sōle nōn ambul___." → ambulāret. "Pāstor umbram petīvit nē in sōle ambul___." → ambulāret. (Same form, different conjunction — illustrate purpose vs. result.)
5. cum + subj. translate: "Cum gubernātor nāvem appropinquantem vidēret, exclāmāvit." → "When/Since the helmsman saw the ship approaching, he cried out."
6. Dative-verb drill: "He envies the rich man." → Hominī dīvitī invidet. "Spare us!" → Parce nōbīs! "He persuaded the sailor." → Nautae persuāsit.
7. PENSVM B vocab fill: "Orpheus, ___ nōbilis, tam pulchrē canēbat ut ferae ___." → fidicen, accēderent (or appropinquārent).
8. Genitive of value: "He values the wares highly." → Mercēs magnī aestimat. "He values life little." → Vītam parvī aestimat.
9. PENSVM C Q&A: "Quōmodo Arīōn servātus est?" → Arīōn ā delphīnō servātus est, quī eum in dorsō suō ad lītus vēxit.
10. Spot the error: "Cum vidēbat nāvem, fūgit." → Cum vidēret nāvem, fūgit. (cum-circumstantial → subj.) "Mercēs multum aestimat." → magnī aestimat.
11. Translate (compound): "When Polycrates had thrown his ring into the sea, a fisherman caught a fish so beautiful that he gave it to the tyrant." → Cum Polycratēs ānulum suum in mare abiēcisset, piscātor piscem cēpit tam formōsum ut eum tyrannō dōnāret. (Note: plupf subj abiēcisset technically c30 territory; you can simplify to cum... abiēcit if needed.)

Session start

Bare (/llpsi-c29): "Cap. XXIX — Nāvigāre Necesse Est. The big consolidation: purpose, result, and command ut-clauses all coexisting (with nē / ut nōn distinction), and cum + subjunctive for circumstantial/causal "when, since". Plus dative verbs (invidēre, parcere, suādēre), genitive of value, and 5th decl. spēs. Where do you want to start — ut clauses, cum clauses, or vocab/dative verbs?"
