Lesson 34 · Review

Six Tenses of the Active Voice — two stems, one synopsis, and a self-check

IVocabulary

This review lesson adds only five words — four adverbs and one verb. Its real work is to gather the whole active voice into a single system you can run through from memory.

subitōsuddenly (adv.)
reportō, -āre, -āvībring back; win, gain

IIThe Six Tenses

Every tense of the indicative active is one of six recipes — three grow from the present stem, three from the perfect stem. Here they are on amō, first person singular, with the tense sign picked out.

TenseHow it is formedamō (1 sg.)English
Presentfirst principal partamōI love
Imperfectpresent stem + -bā-amābamI was loving
Futurepresent stem + -bō (I, II)amāI shall love
Perfectthird principal partamāvīI have loved / I loved
Pluperfectperfect stem + -erā-amāveramI had loved
Future Perfectperfect stem + -eri-amāverōI shall have loved
Rule 1 — Two stems, six tenses

The six tenses divide into two families. The present stem (the present infinitive minus -re: amā-) gives the present, imperfect, and future. The perfect stem (the third principal part minus : amāv-) gives the perfect, pluperfect, and future perfect. Learn a verb's principal parts and all six tenses fall out.

amā- → amābam  ·  amāv- → amāveram

Rule 2 — The future has two recipes

In Conjugations I and II the future is present stem + -bō (amābō, movēbō); in III and IV it is present stem + -a- / -ē- (dūcam, dūcēs…, mūniam, mūniēs…). Watch the one-letter trap: amābō ("I shall love," future) versus amābam ("I was loving," imperfect).

amābō — I shall love  ·  amābam — I was loving

IIIA Full Synopsis of amō

A synopsis runs one verb through every form you have learned, in order. Master this on amō and you can give it for any verb — half from the present stem, half from the perfect.

Present stem: amā-LatinEnglish
Indicative — PresentamōI love
Indicative — ImperfectamābamI was loving
Indicative — FutureamābōI shall love
Imperative — Presentamālove!
Infinitive — Presentamāreto love
Perfect stem: amāv-LatinEnglish
Indicative — PerfectamāvīI have loved
Indicative — PluperfectamāveramI had loved
Indicative — Future PerfectamāverōI shall have loved
Infinitive — Perfectamāvisseto have loved
Rule 3 — Give it in any person

The synopsis is usually shown in the first singular, but you should be able to run it out in any person and number on demand — amās, amābāmus, amāverint. Learn the template, then swap the personal endings.

amāverant — they had loved  ·  amāveritis — you (pl.) will have loved

IVPrincipal Parts to Know

For every reviewed verb the perfect — the third principal part — is the only new form; learn it and the whole perfect system follows. A representative set:

Rule 4 — The perfect is where the surprises hide

The present stem is predictable; it is the perfect stem that varies. It may reduplicate (dedī, crēdidī, repperī), lengthen a vowel (ēgī, fūgī, interfēcī), add an -s- (iussī), add a -u- (docuī), or simply lengthen with no suffix (respondī). Drill the third principal part — the rest is machinery.

agō → ēgī  ·  iubeō → iussī  ·  dō → dedī

VSelf-check

Six out of six before you start the exercises.

Question 1

How is the imperfect active indicative formed?

Right. The imperfect adds the tense sign -bā- to the present stem: amā-bam, "I was loving." The first principal part alone is the present (amō); perfect stem + -erā- is the pluperfect.

Not quite — the imperfect ("was ___-ing") is built on the present stem with a -bā-. Which option shows that?

Question 2

How is the future perfect active indicative built?

Right. The future perfect is the perfect stem plus -eri-, taking -erō in the first singular: amāv-erō, "I shall have loved." Present stem + -bō is the future of Conjugations I–II; perfect stem + -erā- is the pluperfect.

Not quite — the future perfect sits on the perfect stem, and its tense sign carries an i (-eri-), not an ā. Which option is that?

Question 3

The principal parts of interficiō are interficiō, interficere, ___. Which perfect completes them?

Right. interficiō forms its perfect by lengthening the stem vowel: interfēcī, "I killed." It takes neither an -īvī nor a -uī perfect.

Not quite — interficiō makes its perfect by lengthening the vowel to -fēcī, not by tacking on -īvī or -uī. Which form shows that?

Question 4

In the synopsis of amō, which form is built on the perfect stem amāv-?

Right. The pluperfect amāv-eram stands on the perfect stem. The imperfect amābam and the future amābō both grow from the present stem amā-. Half the synopsis comes from each stem.

Not quite — the present stem amā- gives the present, imperfect, and future; the perfect stem amāv- gives the perfect, pluperfect, and future perfect. Which option is a perfect-stem form?

Question 5

In the reading, Perseus victōriam reportāvit. What does reportāvit mean?

Right. reportāvit is the perfect (third principal part reportāvī), third singular: "he won, he brought back." The imperfect would be reportābat ("he was winning"); the future, reportābit ("he will win").

Not quite — the ending -āvit on the perfect stem marks the perfect tense, a completed act. What did Perseus do — once, and done?

Question 6

Which of this lesson's new adverbs means "suddenly"?

Right. subitō means "suddenly." celeriter is "quickly," dēnique is "finally," and graviter (the fourth new adverb) is "heavily, severely."

Not quite — celeriter is "quickly" and dēnique is "finally." Which one names something happening all at once, without warning?
