Grammar introduced in Cap. IX

1. Third declension — this is the big one. Two patterns introduced:

   [A] Consonant-stem (like pāstor, sōl, arbor):

   	sg.	pl.
   nom.	pāstor	pāstōrēs
   acc.	pāstōrem	pāstōrēs
   gen.	pāstōris	pāstōrum
   dat.	pāstōrī	pāstōribus
   abl.	pāstōre	pāstōribus

   [B] i-stem (like ovis, mōns, collis):

   	sg.	pl.
   nom.	ovis	ovēs
   acc.	ovem	ovēs
   gen.	ovis	ovium
   dat.	ovī	ovibus
   abl.	ove	ovibus

   Difference: gen. pl. is -um (consonant-stem) vs. -ium (i-stem). LLPSI doesn't use the term "i-stem" yet but the pattern is clear.

2. Recognizing 3rd-decl. nouns from gen. sg.: nom. and gen. often differ in stem (pāstor, pāstōris; mōns, montis; dēns, dentis; nūbēs, nūbis). Always learn the gen. with the noun.

   Stem recovery rule: in 3rd decl. the stem comes from the gen., not the nom. Drop -is from the gen. sg.: montis → stem mont-; nūbis → nūb-; dentis → dent-; gregis → greg-; pāstōris → pāstōr-. Every other case is built on that stem.

3. Gender in 3rd decl.: not predictable from ending — must be memorized. f.: ovis, vallis, nūbēs, arbor; m.: pāstor, sōl, timor, clāmor, pānis, collis, mōns, dēns, canis.

4. Formal review of all three declensions (Grammatica section makes this explicit):

   • 1st: īnsula, -ae, -am, -ās, -ārum, -īs, -ā, -īs.
   • 2nd m. servus, n. verbum.
   • 3rd: pattern as above.

5. ipse, ipsa, ipsum ("-self," intensive — not reflexive!) — same endings as ille (gen. sg. ipsīus, dat. sg. ipsī). Ovis lupum ipsum videt. "The sheep sees the wolf himself." Different from reflexive sē.

   Agreement of ipse: agrees with the noun being emphasized, not necessarily the subject. Pāstor lupum ipsum videt — emphasis on the wolf ("the wolf himself"). Pāstor ipse lupum videt — emphasis on the shepherd ("the shepherd himself"). Position + agreement together do the work.

6. dum + present indicative = "while": Dum pāstor dormit, ovis abit. "While the shepherd sleeps, the sheep goes off."

7. ut + nom. = "like, as": Oculī lupī lūcent ut gemmae. "The wolf's eyes shine like gems." (Comparison/simile.)

8. suprā + acc. ("above") vs. sub + abl. ("under"). Note sub takes abl. for location (no motion implied here yet).

9. Compound verbs: ad-currit → accurrit (assimilation of d→c). in-pōnit → impōnit (n→m before p).

Common error patterns

• Treating 3rd-decl. nouns as 2nd-decl.: pāstorī mālum dat (correct dat.) vs. pāstorō mālum dat (wrong — student applied 2nd-decl. dat.).
• Wrong gen. pl.: ovum for "of sheep" — wrong; ovis is i-stem, so ovium. Conversely pāstōrium — wrong; consonant-stem, so pāstōrum. Special case: canum (NOT canium).
• Confusing nom. pl. (-ēs) and acc. pl. (-ēs): identical in 3rd decl.! Word order and verb agreement disambiguate. Pāstōrēs ovēs vident. — context: shepherds (nom. pl.) see sheep (acc. pl.).
• ēst (eats) vs. est (is): in unmacroned text, identical. Lupus ovem ēst "the wolf eats the sheep." Watch the long ē.
• Forgetting that canis is m. (or f.) not n.: canis niger (m.) — correct; not canis nigrum.
• 3rd-decl. abl. sg. -e vs. dat. sg. -ī: pāstōre (abl., often with prep.: ā pāstōre) vs. pāstōrī (dat., often with verb of giving: pāstōrī cibum dat). Easy to swap.
• ipse confused with sē: Ovis sē videt = "the sheep sees herself" (reflexive). Ovis lupum ipsum videt = "the sheep sees the wolf himself" (intensive). Different jobs.
• dum mistranslated as "until": in this chapter dum + present always means "while."
• mōns / dēns nominative drops -t-: nom. sg. mōns (< monts), gen. montis. Don't write montis for nom. or mōns for gen.
• Assuming every 3rd-decl. -is noun is i-stem (or every one is consonant-stem): must check. ovis, collis, vallis, pānis are i-stem (gen. pl. -ium); but canis is consonant-stem (gen. pl. canum). Memorize gen. pl. with the noun.
• Misparsing nūbēs as only plural: sg. nom. is also nūbēs (3rd-decl. f. with -ēs nom. sg.). Context decides. Nūbēs in caelō est (sg.) vs. Nūbēs in caelō sunt (pl.).
• ipse default-agreeing with the subject: don't auto-attach to the subject. Agree with whatever noun is being emphasized. Lupus ovem ipsam ēst = "the wolf eats the very sheep" — ipsam with ovem, not lupus.
• Using sub + acc. for static "under": in this chapter "under" = location (no motion), so sub + abl. Pāstor sub arbore dormit (correct, abl.); sub arborem dormit (wrong — that would be motion, "down under to the tree").

Exercise menu

1. Decline a 3rd-decl. noun fully: "Decline pāstor sg + pl, all 5 cases." → pāstor, pāstōrem, pāstōris, pāstōrī, pāstōre; pāstōrēs, pāstōrēs, pāstōrum, pāstōribus, pāstōribus. Then ovis (with -ium gen. pl.).
2. Single-form fill: "Give dat. sg. of arbor." → arborī. "Acc. pl. of mōns." → montēs. "Gen. pl. of ovis." → ovium. Cycle through traps.
3. Identify the case (parsing): "ovibus — what cases?" → dat. or abl. pl. "pāstōris" → gen. sg. "nūbēs" → nom. sg., nom. pl., or acc. pl. (3 possibilities).
4. PENSVM A fill: "Pāstor cum can- et ov- ad arbor- it." → cane, ovibus, arborem. "In coll- ūna arbor est." → colle.
5. Adjective agreement with 3rd-decl. noun: "ovis nigr-" → nigra (f. nom.). "lupum ips-" → ipsum (m. acc.). "in monte alt-" — well, altus not in c9, but magnō: "in monte magn-" → magnō (m. abl. sg.; 2nd-decl. adj. with 3rd-decl. noun).
6. Spot the error: "Pāstor ovem nigrum quaerit." → ovem nigram (ovis is f.). "Lupus ē silvae venit." → ē silvā (abl., not gen.). "Canēs cum pāstōrum ambulant." → cum pāstōre or cum pāstōribus (abl.).
7. ipse vs. sē: "The wolf sees the sheep itself." → Lupus ovem ipsam videt. "The sheep does not see the wolf himself." → Ovis lupum ipsum nōn videt. "The shepherd looks at himself." → Pāstor sē aspicit / videt.
8. PENSVM C Q&A: "Quot ovēs habet pāstor?" → Centum ovēs (habet) — ūnam nigram et ūndēcentum albās. "Cūr lupus ovem nigram nōn ēst?" → Quia canis accurrit (et lupum petit).
9. Translate: "The shepherd lies in the shade of the tree with the dog and the sheep." → Pāstor in umbrā arboris cum cane et ovibus iacet. "The wolves seek the sheep through the forest." → Lupī ovēs per silvam petunt / quaerunt.
10. Convert clauses with dum: "While the shepherd sleeps, the dog watches." (give simpler vocab) → Dum pāstor dormit, canis aspicit / spectat. "While the wolf seeks food, the dog runs up." → Dum lupus cibum quaerit, canis accurrit.
11. Stem-recovery drill: give nom./gen. pair, ask for stem. mōns / montis → mont-. nūbēs / nūbis → nūb-. grex / gregis → greg-. dēns / dentis → dent-. pāstor / pāstōris → pāstōr-.
12. Sort consonant-stem vs. i-stem (gen. pl. -um vs. -ium): give a list, ask the student to bin each. pāstor, ovis, arbor, mōns, canis, collis, vallis, nūbēs, sōl, pānis → consonant: pāstor, arbor, canis, sōl; i-stem: ovis, mōns, collis, vallis, nūbēs, pānis.
13. Scene-description with chapter geography: prompt the student to describe a picture using sub arbore, suprā montem, in valle, dum pāstor dormit. E.g. "Pāstor sub arbore dormit; suprā montem sōl lūcet; dum pāstor dormit, lupus ē silvā venit."
14. Contrast sē vs. ipse/ipsa/ipsum (near-minimal pairs): "Pāstor ___ videt." (himself, reflexive) → sē. "Pāstor lupum ___ videt." (the wolf himself) → ipsum. "Ovis ___ in rīvō videt." (herself) → sē. "Ovis lupum ___ timet." (the wolf himself) → ipsum.

Session start

Bare (/llpsi-c9): "Cap. IX — Pastor et Oves. The chapter that introduces the third declension — both consonant-stems (pāstor) and i-stems (ovis). Also ipse (intensive, distinct from reflexive sē) and dum + present. Where do you want to start — declensions, ipse, or new verbs?"

With topic: jump in.

After ~6–8 items, offer continue/switch/move on. For broader 3rd-decl. practice, suggest continuing into c10/c11 where more 3rd-decl. nouns pile up.
