GrammarPrimary & Secondary Tenses (Sequence of Tenses)

A&G §482–483|5 rules|0 practice questions

Sequence of tenses decides which subjunctive Latin reaches for inside a subordinate clause, and the clue is the time-flavor of the main verb. Present, future, and future perfect are PRIMARY; imperfect, perfect, and pluperfect are SECONDARY.

The rule is mechanical. Primary main → present subj. (incomplete) or perfect subj. (complete). Secondary main → imperfect subj. (incomplete) or pluperfect subj. (complete).

Rogō quid faciās — "I ask what you are doing." Rogāvī quid facerēs — "I asked what you were doing." The trap: the historical present counts as EITHER sequence, depending on whether the author is reliving the action or narrating it from outside.

Pattern

PRIMARY main → pres. subj. (incomplete) | pf. subj. (complete)

SECONDARY main → impf. subj. (incomplete) | plpf. subj. (complete)

Sequence of Tenses

The main verb's time-flavor decides the subjunctive's tense; "incomplete vs. complete" decides which of the two within that flavor.

Primary = present, future, future perfect. Secondary = imperfect, perfect, pluperfect. The historical present can take either — author's choice.

Sequence Grid + the Real-World Exceptions

PRIMARY main + INCOMPLETE subord. → pres. subj.

rogō quid faciās — "I ask what you are doing"

critical

PRIMARY main + COMPLETE subord. → pf. subj.

rogō quid fēcerīs — "I ask what you have done"

critical

PRIMARY main + FUTURE subord. → fut. periphrastic (-ūrus sit)

rogō quid factūrus sīs — "I ask what you will do"

important

SECONDARY main + INCOMPLETE subord. → impf. subj.

rogāvī quid facerēs — "I asked what you were doing"

critical

SECONDARY main + COMPLETE subord. → plpf. subj.

rogāvī quid fēcissēs — "I asked what you had done"

critical

SECONDARY main + FUTURE subord. → fut. periphrastic (-ūrus essēs)

rogāvī quid factūrus essēs — "I asked what you would do"

important

Future indicative main → counts as PRIMARY

rogābō quid faciās — "I shall ask what you are doing"

common

Imperative / fut. perfect main → both count as PRIMARY

scrībe ut nōs moneās; rogāverō ut moneat

common

EXCEPTION: Historical present — EITHER sequence

mittit ut videat OR mittit ut vidēret — both attested

common

EXCEPTION: Perfect-as-aorist ("I asked") = SECONDARY

rogāvī quid facerēs — simple past meaning

critical

EXCEPTION: Perfect-with-have ("I have asked") = sometimes PRIMARY

rogāvī quid fēcerit — perfect-definite force (§ 485. a)

rare

EXCEPTION: Repeated/general action — present subj. even after past main

Common in cum-clauses and characteristic clauses ("whenever X")

See It In Action

ego mea video quid intersit

I see what is at stake for me

— Cic. Cat. iv. 9

Textbook PRIMARY/PRIMARY. Present main video, present subjunctive intersit — the stake is still ongoing relative to the seeing.

Caesar, cum ... urgeri ab hoste vidisset, tribunos militum monuit ut coniungerent

Caesar, when he had seen (the seventh legion) being pressed by the enemy, warned the tribunes to join their legions together

— B. G. ii. 26

Textbook SECONDARY/SECONDARY. Perfect main monuit sets the past frame; the ut-clause lands as imperfect subjunctive coniungerent — incomplete relative to the warning.

legatis imperat ... uti quam plurimas possent ... curarent

he orders his lieutenants to see to it that they build as many ships as they could in the winter, and refit the old ones

— B. G. v. 1

Historical present, secondary sequence. Imperat LOOKS primary, but the imperfect subjunctives possent and curarent prove Caesar is mentally treating it as a perfect.

Caesar ... monet ut ... omnes suspiciones vitet ... ut quae agat, quibuscum loquatur scire possit

He warns (Dumnorix) to avoid all suspicions in the future ... so that he might know what he is doing and with whom he is speaking

— B. G. i. 20

Same author Caesar, opposite call. Monet and ponit are also historical presents, but here he slides them into PRIMARY sequence — the present subjunctives are the proof. The historical present really does take either.

Historical Present: PRIMARY or SECONDARY?

A present-tense verb in past narrative (mittit, iubet, imperat) can trigger EITHER sequence. The author's stance — vivid reliving vs. summarizing past — is the only clue.

Treated as PRIMARY

Author is RELIVING the action — feels present

monet ut suspiciones vitet

he warns (him) to avoid suspicions — pres. subj.

Treated as SECONDARY

Author is NARRATING from outside — feels past

imperat ... uti ... possent

he orders ... that they could — impf. subj.

Tip: Read backwards. The subjunctive's tense IS the answer — it tells you which sequence the author chose. Don't try to predict it from the main verb alone.

Quick Check

In Caesar, cum septimam legionem urgērī vidisset, tribūnōs monuit ut signa coniungerent (after B. G. ii. 26), why is coniungerent in the imperfect subjunctive rather than the present?

Study Tips

•Before parsing the subjunctive, look at the main verb. Decide PRIMARY or SECONDARY first — that one question solves 90% of subjunctive-tense puzzles.
•Memorize the four-cell grid: pres/fut/fut-pf main → pres or pf subj.; impf/pf/plpf main → impf or plpf subj. Pres = ongoing, pf = done, in BOTH columns.
•When you meet a vivid present in narrative (mittit, iubet, imperat in past context), pause: the historical present can take EITHER sequence — Caesar tilts secondary, Cicero often primary.
•Don't confuse SUBJUNCTIVE tense with TIME. The present subjunctive in rogō quid faciās doesn't mean "now" — it means "still in progress relative to the main verb."
