Grammar introduced in Cap. X

1. Active infinitive of all four conjugations + irregulars:

   conj.	inf. ending	example
   [1]	-āre	vocāre, amāre, portāre
   [2]	-ēre	vidēre, habēre, movēre
   [3]	-ere (short)	pōnere, dūcere, vīvere
   [3 -iō]	-ere	capere, facere, accipere
   [4]	-īre	audīre, venīre, dormīre
   irreg.	—	esse, ēsse, posse, velle, īre

   Distinguish 2nd-conj. vidēre (long ē) from 3rd-conj. vīvere (short e).

2. Passive infinitive:

   conj.	inf. passive	example
   [1]	-ārī	vocārī, portārī
   [2]	-ērī	vidērī, tenērī
   [3]	-ī	pōnī, emī, edī
   [4]	-īrī	audīrī, reperīrī

   Piscēs numerārī nōn possunt. "The fish cannot be counted."

3. Accusative + infinitive (introduced informally — formalized in c11) — for indirect statement and after verbs of perception:

   • Mārcus Quīntum cadere videt. "Marcus sees Quintus fall(ing)."
   • Iūlius puerum vocāre audit. "Julius hears the boy calling."
   • Aemilia Quīntum ā Iūliō portārī videt. "Aemilia sees Quintus being carried by Julius."

4. posse (irregular) — only 3sg potest and 3pl possunt drilled here; full paradigm in c11.

   • Hominēs ambulāre possunt. "Men can walk."
   • Piscēs in āere spīrāre nōn possunt.

5. velle (irregular) — only vult (3sg) and volunt (3pl).

   • Pueri nīdōs quaerere volunt.

6. Third-declension neuters in -us, -en: corpus, corporis; flūmen, flūminis. Plural in -a: flūmina, corpora. (Fully detailed in c11; appear here.)

7. i-stem neuters mare and animal: abl. sg. -ī (not -e), nom./acc. pl. -ia, gen. pl. -ium.

8. 3rd-decl. -iō nouns: leō, leōnis (gen. drops -n then re-adds it: stem leōn-); pulmō, pulmōnis; homō, hominis (note vowel change to i).

9. Causal quod (= quia): "because." Canis volāre nōn potest, quod ālās nōn habet.

10. necesse est + dat. of person + infinitive: "it is necessary for X to ___." Spīrāre necesse est hominī. "Breathing is necessary for a human."

11. Infinitive as subject: the inf. itself can be the grammatical subject of est / necesse est. Vīvere necesse est. ("To live is necessary.") Errāre hūmānum est.

12. cum + indic. as temporal "when/whenever" — distinct from cum + abl. preposition ("with"). Cum sōl lūcet, avēs canunt.

Common error patterns

• Confusing infinitive endings -ere vs. -ēre (3rd vs. 2nd conj.): vidēre (2nd, long ē) vs. vīvere (3rd, short e). Without macrons, only memory tells you. vidēre potest, vīvere potest.
• Wrong passive infinitive: pōnāre — wrong; 3rd-conj. passive inf. is just -ī: pōnī. Same: emī, edī, claudī.
• Treating posse as regular: Hominēs ambulāre potent — wrong; 3pl is possunt. Iūlia volāre nōn potest. (3sg, not poteset.)
• Forgetting acc. in acc.+inf.: Mārcus videt Quīntus cadere — wrong; should be Mārcus Quīntum cadere videt (acc. subject of inf.).
• esse vs. ēsse: Mēdus servus ēsse nōn vult — wrong if you mean "to be"; should be esse (short e). Nēmō gemmās ēsse potest (long ē, "to eat").
• i-stem neuter abl. sg. -ī forgotten: in mare est — abl. of mare is marī, so in marī. Same for animal → animālī.
• Gen. pl. of i-stem neuter -ium forgotten: plēna piscium — correct; piscium not piscum. Same marium, animālium, flūminum (wait — flūmen is consonant-stem n., so gen. pl. flūminum is right; mare is i-stem n. → marium).
• homō declension: homō, hominis — student writes homonem — wrong; acc. is hominem (vowel change in stem). Pl. hominēs, hominum.
• quod (because) vs. quod (n. relative): same form. Context: quod + clause with finite verb usually = "because"; quod with antecedent noun = relative.
• Translating "wants" with present of amāre: Iūlia lūdere amat — wrong; use vult: Iūlia lūdere vult.
• Acc. of āer: students assume 1st-decl. āeram — wrong; āēr is 3rd decl., acc. āerem.
• Mixing volāre (to fly) with velle (to want) because of similar vol- root: aquila volat (flies) vs. aquila volat capere — wrong; "wants to" is vult (aquila capere vult).
• quia vs. quod: both = "because" and are largely interchangeable; don't treat them as different in meaning.

Exercise menu

1. Give the infinitive of a known verb: "Infinitive of portat?" → portāre. "Of videt?" → vidēre. "Of pōnit?" → pōnere. "Of capit?" → capere. "Of audit?" → audīre. Cycle through all 4 conjugations + -iō.
2. Identify conjugation from infinitive: "movēre — which conj.?" → 2nd. "vīvere?" → 3rd. "aperīre?" → 4th. "facere?" → 3rd -iō.
3. Active → passive infinitive: "portāre → ?" → portārī. "vidēre → ?" → vidērī. "pōnere → ?" → pōnī. "audīre → ?" → audīrī.
4. potest / possunt fill: "Pisces in āere spīrāre nōn ___." → possunt. "Iūlia natāre nōn ___." → potest. "Aquila parvās avēs capere ___." → potest.
5. Acc. + inf. simple: "Translate: 'Julius hears the boy.'" → Iūlius puerum audit. Then: "'Julius hears the boy calling.'" → Iūlius puerum vocāre audit. Then passive: "'Aemilia sees Quintus being carried.'" → Aemilia Quīntum portārī videt.
6. PENSVM A fill: "Avēs in āer- vol-. Pisc- in aquā nat-." → āere, volant, piscēs, natant. "Spīr- necesse est homin-." → spīrāre, hominī.
7. Spot the error: "Hominēs vidēre deōs nōn potest." → possunt (subject is plural). "Pisces ēsse possunt gemmās." — wrong; gemmae edī nōn possunt or nēmō gemmās ēsse potest. "Iūlia volāre amat." → Iūlia volāre vult.
8. 3rd-decl. forms (more): "Decline homō sg + pl." → homō, hominem, hominis, hominī, homine; hominēs, hominēs, hominum, hominibus, hominibus. Same for leō, vōx, pēs, mare, animal.
9. PENSVM C Q&A: "Quae bēstiae ōva pariunt?" → Avēs (ōva pariunt). "Cūr rāmus Quīntum sustinēre nōn potest?" → Quia rāmus tenuis est et Quīntus crassus est. "Quid agit Mercurius?" → Mercurius volat / imperia deōrum (ad hominēs) portat.
10. Translate (using acc.+inf.): "Marcus sees Quintus fall to the ground." → Mārcus Quīntum ad terram cadere videt. "Aemilia sees Quintus being placed on the bed." → Aemilia Quīntum in lectō pōnī videt / aspicit. "Julius hears the boy shouting." → Iūlius puerum clāmāre audit.
11. PENSVM B cloze: contextual vocab fills from the chapter. "Aquila est avis magna quae ___ habet et ___ potest." → ālās, volāre. "Piscēs in ___ natant; in āere spīrāre nōn ___." → aquā / marī, possunt.
12. quia ↔ quod swap: convert quia-clause to quod-clause (and vice versa). "Canis volāre nōn potest, quia ālās nōn habet." → ...quod ālās nōn habet. "Quīntus cadit quod rāmus tenuis est." → ...quia rāmus tenuis est.
13. Conjugation ID by stress / vowel length: pronounce inf. with correct stress; mark macron. "videre — mark macron + conj.?" → vidēre, 2nd (long ē, stressed). "vivere?" → vīvere, 3rd (short e, antepenult stress). Cycle: movēre / pōnere, sustinēre / cadere, audēre / ascendere.

Session start

Bare (/llpsi-c10): "Cap. X — Bestiae et Homines. Two huge new things: the infinitive (active and passive, all 4 conjugations) and the accusative + infinitive construction (with vidēre, audīre, etc.).
