(a) Why this lesson exists

The single most common word attached to a subjunctive in your syllabus is ut — and it means at least three different things (purpose, result, indirect command), with ne, quo, and cum running the same subjunctive machinery from other doorways. The exam never asks "what mood is this?"; it asks "what does this clause do?" — and builds wrong answers from the other doors. Today you learn to tell the doors apart from inside the sentence, using the clues Latin actually gives.

The door-identification table:

Door Signal Negative The tell
Purpose (ut/ne + subj.) follows an action verb ne answers "why? with what goal?"
Purpose with comparative quo + comparative + subj. quo verius … possis (L1!)
Result (ut + subj.) a setup word: ita, tam, adeo, tantus, sic ut non answers "to what degree? with what outcome?"
Indirect command (ut/ne + subj.) follows ask/order/warn/beg (oro, moneo, impero, peto) ne reports a command, not a goal
Cum + subjunctive circumstantial/causal/concessive "when/since/although" — background
Cum + indicative pure time-stamp, general truth "at the time when / whenever"

The fastest sorter on the exam: a negative clause with ut non is result; with ne it's purpose or command. And a setup word (ita, adeo, tam) earlier in the sentence almost guarantees result.

(b) Drilled on your syllabus — all from the Vesuvius and ghost letters

Set 1 — purpose and command in the rescue (Ep. 6.16.8–11):

accipit codicillos Rectinae … : ut se tanto discrimini eriperet orabat. … Properat illuc unde alii fugiunt, rectumque cursum recta gubernacula in periculum tenet adeo solutus metu, ut omnes illius mali motus omnes figuras ut deprenderat oculis dictaret enotaretque. … Iam navibus cinis incidebat, quo propius accederent, calidior et densior … Cunctatus paulum an retro flecteret, mox gubernatori ut ita faceret monenti 'Fortes' inquit 'fortuna iuvat: Pomponianum pete.'

1. ut se tanto discrimini eriperet orabat — which door? What's the signal, and who is se? (L4's reflexive rule pays off again.) 2. adeo solutus metu, ut … dictaret enotaretque — which door, and what word gives it away before you even reach ut? Translate the clause. 3. quo propius accederent, calidior et densior — this quo is NOT the purpose-quo of L1. What is it doing? ("The nearer they…, the …") 4. Cunctatus paulum an retro flecteret — name the construction launched by an. What was the Elder deliberating? 5. gubernatori ut ita faceret monenti — untangle: who advises whom to do what? Which door is ut faceret, and what participle carries the advising? 6. Translate the Elder's reply: 'Fortes fortuna iuvat: Pomponianum pete.' Why is pete NOT subjunctive?

Set 2 — result at full scale (Ep. 6.20.3, from L4, now from the grammar side):

illa vero nocte ita invaluit, ut non moveri omnia sed verti crederentur.

7. Two separate signals mark this as result, one before the ut and one inside it. Name both.

Set 3 — purpose and cum in the ghost letter (Ep. 7.27.1/14):

Et mihi discendi et tibi docendi facultatem otium praebet. … igitur perquam velim scire … (and, closing the letter:) altera tamen fortius, ne me suspensum incertumque dimittas, cum mihi consulendi causa fuerit, ut dubitare desinerem.

8. ne me suspensum incertumque dimittas — which door? What is Pliny asking Sura (not) to do? 9. cum mihi consulendi causa fueritcum + perfect subjunctive: which flavor of cum (time-stamp, cause, concession)? Defend your choice. 10. ut dubitare desinerem — purpose or result? The clue is what the clause explains: the causa. Translate the whole closing run.

Set 4 — the cum-contrast pair (both from your texts):

(a) Ep. 6.16.6 (the danger) … conspicuo tamen et cum cresceret proximo … (b) Ep. 6.20.18 (the sun after the cloud) … sol etiam effulsit, luridus tamen qualis esse cum deficit solet.

11. (a) has cum + subjunctive, (b) has cum + indicative (deficit). Translate both cum-clauses and explain why each takes its mood.

(c) The trap gallery

(d) Summary drill (skill 1.C)

One English sentence each: (i) Ep. 6.16.8–11 — the Elder's change of mission and his famous decision (capture both the rescue purpose and the fearlessness result); (ii) Pliny's closing request to Sura (7.27) — what he asks and why.

(e) Answer key

1. Indirect command (door 4): signal is orabat ("she was begging that he rescue her"). se = Rectina, the subject of orabat — she begs him to snatch herself from so great a peril. (Not purpose: the clause reports the content of her plea.) 2. Result, flagged by adeo ("to such a degree freed from fear that he kept dictating and noting down every movement, every shape of that disaster as he caught them with his eyes"). The result clause IS the characterization: scientific calm, measured in syntax. 3. Relative/proportional quo with comparatives: "the nearer they approached, the hotter and denser (the ash fell)." A proportion, not a purpose — no goal is expressed. (Subjunctive by attraction inside the narrative frame; the proportional reading is what's tested.) 4. Indirect deliberative question: "having hesitated a little whether he should turn back." an + subjunctive reports the internal debate — the one moment doubt enters the letter. 5. The helmsman (gubernatori … monenti, dative with the participle of advising) advises him (the Elder) ut ita faceret — "to do exactly that," i.e., turn back. Door: indirect command hanging from a participle. The Elder overrules him in the next breath. 6. "Fortune favors the brave: make for Pomponianus." pete is a direct imperative — quoted speech, a real command to a real helmsman, needing no subjunctive wrapper. (Note the textual variant: some editions print Pomponianum, others a place-name; our source text reads Pomponianum.) 7. Before: ita invaluit ("grew so strong"). Inside: ut non (not ne) — the negative of result. "…that all things were believed not (merely) to be shaking but to be overturning." 8. Purpose/indirect plea with ne: "so that you do not send me away hanging and uncertain." A negative request — ne, not ut non, is the tell. 9. Causal cum: "since my reason for consulting you has been…" — Pliny is justifying the demand he just made, not time-stamping it. (Concession makes no sense; pure time would prefer indicative.) 10. Purpose — it unpacks the causa: "since my reason for consulting (you) has been that I might stop doubting." Full run: "but the second (answer give) the more bravely, so that you don't dismiss me hanging and uncertain, since my reason for consulting you was precisely that I might stop doubting." 11. (a) "…(the danger) now close at hand as it grew" — cum + imperfect subjunctive: circumstantial, the growth is the surrounding situation, not a date. (b) "…lurid, the way (the sun) usually is when it is eclipsed" — cum + present indicative: a general, repeatable truth about eclipses. Background situation → subjunctive; standing fact → indicative.

Summary models (d): (i) "What began as a scientist's outing became a rescue mission: the Elder sailed straight into the danger zone to save Rectina and others, so unafraid that he dictated observations en route, and when the helmsman urged turning back he refused — 'Fortune favors the brave.'" (ii) "Pliny begs Sura to give a real verdict rather than diplomatic balance, since the whole point of asking was to be freed from doubt."

Exam strategy: Q1 (short answer) routinely asks "what does X ask/order/urge?" — the answer always lives in an ut/ne clause. Practice answering in English with the content of the clause, not its grammar: the rubric wants "she begged him to rescue her," not "an indirect command."
