Grammar introduced in Cap. XVIII

1. Adverbs from adjectives. This is the headline grammar.

   • 1st/2nd-decl. adjective (-us -a -um) → adverb in -ē: stultus → stultē, rēctus → rēctē, pulcher → pulchrē, foedus → foedē, prāvus → prāvē.
   • 3rd-decl. adjective (-is -e or consonant-stem) → adverb in -iter: fortis → fortiter, brevis → breviter, turpis → turpiter, gravis → graviter, levis → leviter. Caveat: facilis → facile (irregular, only seen later).
   • Comparative adv. = neuter sg. of comparative adj.: -ius. rēctius, fortius, pulchrius, turpius, gravius, sevērius.
   • Superlative adv. = -issimē (or -errimē for -er stems, -illimē for a few): rēctissimē, pulcherrimē, fortissimē, turpissimē, sevērissimē, facillimē.

   Examples from the chapter:

   • Sextus rēctē et pulchrē scrībit.
   • Mārcus prāvē et turpiter scrībit.
   • Sōl clārius lūcet quam lūna.
   • Nēmō prāvius scrībit quam Mārcus.
   • Rōmānī fortissimē pugnant.

2. īdem, eadem, idem (= is/ea/id + -dem). Decline like is/ea/id but watch the m → n before -dem: acc. m. sg. eundem (< eum-dem), acc. f. sg. eandem, gen. pl. eōrundem / eārundem. Nom. n. sg. is idem (drops the -d), nom. m. sg. is īdem.

3. quisque, quaeque, quodque "each (one)." Declined: nom. quisque, quaeque, quodque; acc. quemque, quamque, quodque; gen. cuiusque; dat./abl. cuique. Often after a relative or interrogative: quī... is..., quod vocābulum... id...

4. uterque, utraque, utrumque "each of the two." Gen. utrīusque, dat. utrīque. Utramque linguam scit = he knows both languages.

5. Numerical adverbs: semel, bis, ter, quater, quīnquiēs, sexiēs, septiēs, octiēs, noviēs, deciēs. Quotiēs? / totiēs (how often / so often). E.g. Mārcus h litteram deciēs scrībit.

6. Passive 3rd-pers. (review/extension): reperītur, reperiuntur; iunguntur, coniunguntur; audītur; fit, fiunt ("becomes, become" — passive of facere). Sine vōcālī syllaba fierī nōn potest.

7. Letter-and-sound vocab: vōcālis (vowel), cōnsonāns (consonant), syllaba, vocābulum, sententia. The Latin alphabet has 23 letters (A–Z minus J, U, W); vowels are a e i o u y.

Common error patterns

• Adverb suffix mismatch: fortē (wrong) for fortiter; gravē (wrong) for graviter. Rule: 3rd-decl. adj. → -iter, not -ē.
• -ē vs -ius (positive vs. comparative): student says Sextus rēcte scrībit quam Mārcus — needs comparative rēctius (because quam is present).
• Confusing superlative adv. with adj.: Mārcus est pulcherrimē — wrong; for "Marcus is most beautiful" use adj. pulcherrimus. The adv. modifies a verb: pulcherrimē scrībit.
• eundem vs eum : student writes eum-dem instead of eundem (m → n before d). Same for eandem (acc. f. sg.).
• quisque word order: usually follows a superlative or relative — suam cuique tabulam reddit, quaeque syllaba vōcālem habet. Don't put it first as a subject by itself.
• Counting adverbs vs. ordinals: bis "twice" ≠ secundus "second"; ter ≠ tertius.
• deest / dēsunt is de- + esse: 3sg deest, 3pl dēsunt. Imperf. deerat / dēerant. Likewise superest / supersunt.

Exercise menu

(Order roughly easiest → hardest. Single-concept items first; after an error, give a simpler similar item to confirm the fix.)

1. Form the adverb (positive): "Adverb of stultus?" → stultē. "Adverb of fortis?" → fortiter. "Adverb of gravis?" → graviter. (Mix -us and -is adjectives.)
2. Form comparative & superlative adv.: "Comp. and sup. of rēctē?" → rēctius, rēctissimē. "Of fortiter?" → fortius, fortissimē. "Of pulchrē?" → pulchrius, pulcherrimē.
3. PENSVM A-style (single-blank ending): "Sextus rēct— et pulch— scrībit, sed Mārcus prāv— et turpi— scrībit." → rēctē, pulchrē, prāvē, turpiter.
4. Pick adv. or adj.: "Iūlia ___ (pulcher) puella est, sed Sextus ___ (pulcher) scrībit." → pulchra, pulchrē.
5. Decline īdem / eadem / idem in a slot: "Acc. m. sg.?" → eundem. "Acc. f. sg.?" → eandem. "Gen. sg.?" → eiusdem. "Dat./abl. pl.?" → iīsdem (eīsdem).
6. Counting-adv. drill: "How do you say 'three times'?" → ter. "Six times"? → sexiēs. "Mārcus litteram H ___ scrībit (10×)." → deciēs.
7. PENSVM C Q&A (use chapter content): "Quot sunt litterae Latīnae?" → Vīgintī trēs litterae Latīnae sunt. "Quālēs sunt litterae Mārcī?" → Foedae (et turpēs) sunt. "Quis rēctissimē scrībit?" → Sextus rēctissimē scrībit.
8. Spot the error: "Mārcus foedē scrībit quam Titus." → needs comparative foedius. Or: "Magister sevēre Mārcum reprehendit." → adv. is sevērē with macron (or accept; better target: "Magister Mārcum sevērissimus reprehendit." → sevērissimē.)
9. Translate (En → La): "Sextus writes more correctly than Marcus." → Sextus rēctius scrībit quam Mārcus. "No one writes worse than Marcus." → Nēmō prāvius scrībit quam Mārcus.
10. Parse: "pulcherrimē" → adv., superlative of pulchrē (< pulcher). "eundem" → acc. m. sg. of īdem (m → n before -dem).

Session start

Bare (/llpsi-c18): "Cap. XVIII — Litterae Latinae. Headline: adverbs. Adj. -us → adv. -ē (rēctē, pulchrē); adj. -is → adv. -iter (fortiter, graviter); comparative -ius, superlative -issimē. Plus īdem, eadem, idem and the counting adverbs (semel, bis, ter, …, deciēs). Where do you want to start — adverb formation, īdem, or the counting adverbs?"
