## 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?"
