Sequence of Tenses

A&G §481–479|14 rules|0 practice questions

When you tuck a subjunctive clause inside a main clause, Latin makes the two tenses talk to each other. The main verb sets a clock — present-ish or past-ish — and the subordinate subjunctive picks the tense that matches it.

Rogō quid faciās ("I ask what you are doing") is primary; the past version flips every tense down a step: rogāvī quid facerēs ("I asked what you were doing").

This is the rule the AP exam tests more than any other. The trap isn't the rule — it's translation. Latin's imperfect subjunctive after a past verb almost never means English past simple.

It usually means "was V-ing" or "would V." Get that mapping wrong and the whole sentence collapses.

GRAM-2.CThere are six tenses of verbs in the indicative mood: present (____[s], is/are ____ing), imperfect (was/were ____ing, used to ____), future (will ____), perfect (____ed, has/have ____ed, did ____), pluperfect (had ____ed), and future perfect (will have ____ed).

Pattern

PRIMARY main → present subj. (incomplete) | perfect subj. (completed)

SECONDARY main → imperfect subj. (incomplete) | pluperfect subj. (completed)

Sequence of Tenses

Match a present/future-zone main verb to a present/perfect subjunctive; match a past-zone main verb to an imperfect/pluperfect.

Choose the tense first by sequence (primary vs. secondary), THEN by whether the subordinate action is still going or already finished.

The Sequence Grid (and Its Exceptions)

PRIMARY main + incomplete dep. → present subj.

scrībit ut nōs moneat — "he writes to warn us"

critical

PRIMARY main + completed dep. → perfect subj.

rogō quid fēceris — "I ask what you did/have done"

critical

PRIMARY main + future-leaning dep. → fut. act. ptcp. + sim

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

important

SECONDARY main + incomplete dep. → imperfect subj.

scrīpsit ut nōs monēret — "he wrote to warn us"

critical

SECONDARY main + completed dep. → pluperfect subj.

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

critical

SECONDARY main + future-leaning dep. → fut. act. ptcp. + essem

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

important

Future Perfect ind. in dep. → perfect or pluperf. subj.

dēmōnstrat sī vēnerint, multōs interitūrōs — "if they (will have) come"

important

Perfect ind. as PRIMARY ("have done," present-feel)

ea adhibita doctrīna est quae...possit — "such instruction has been given as can..."

common

Perfect subj. after primary main = past of any flavor

nōn dubitō quīn omnēs scrīpserint — "have written / wrote / were writing"

important

Result clause exception: perf. subj. after secondary main

Hortēnsius ārdēbat...sīc ut...vīderim — "as I have never seen"

important

Historical present → primary OR secondary (writer's choice)

rogat ut cūret quod dīxisset — primary verb, secondary subj.

common

Historical present + cum-temporal → forced secondary

quō cum vēnisset cōgnōscit — "when he had come, he learns"

important

Historical infinitive → ALWAYS secondary

Caesar...flāgitāre, quod essent pollicitī — pluperf. subj.

important

Contrary-to-fact + deliberative ignore sequence

quaerō cūr nōn dēfenderem — "I ask why I was not to defend"

common

Quaerō, quid faciat

I ask what he is doing

— Sen. Ep. xx.122.15

Textbook primary sequence: present main verb + present subjunctive for action still in progress at the time of asking.

monet ut illum locum effodī iubeant

he advises them to order that the place be dug up

— Plin. Ep. vii.27.11

Indirect command takes the same sequence rule as indirect question — primary main triggers present subjunctive when the ordered action is still ahead.

Diū cum esset pugnātum, impedimentīs castrīsque nostrī potītī sunt

After they had fought for a long time, our men took possession of the baggage and camp

— B. G. i.26.4

Secondary main verb (perf. potītī sunt) + completed subordinate action (had fought) → pluperfect subjunctive. The cum-clause sets the scene before the main action.

Caesar Haeduōs frūmentum, quod essent pollicitī, flāgitāre

Caesar kept demanding from the Haedui the grain which they had promised

— B. G. i.16.1

The historical infinitive (flāgitāre) looks present but counts as secondary for sequence — that's why essent pollicitī is pluperfect, not perfect.

Translating Subjunctive Tenses by Sequence

primary, present subj.

"is V-ing" / "V-s" / "will V" — incomplete or future-leaning at speaker's now

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

primary, perfect subj.

"did V" / "have V-ed" / "was V-ing" — any past flavor

rogō quid fēceris = "I ask what you did / have done / were doing"

secondary, imperfect subj.

"was V-ing" / "would V" — almost NEVER plain English past

rogāvī quid facerēs = "I asked what you were doing" (NOT "what you did")

secondary, pluperfect subj.

"had V-ed" — already done before the main verb's past moment

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

either sequence, future periphrastic

"would V" / "was going to V" — uses fut. act. ptcp. + sim/essem

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

Primary vs. Secondary Sequence

The whole rule pivots on one decision: does the main verb sit in the present/future zone or the past zone?

Primary Sequence

main verb = present, future, fut. perfect (or perf. felt as present)

rogō quid faciās

I ask what you are doing

Secondary Sequence

main verb = imperfect, perfect ("did"), pluperfect, historical inf.

rogāvī quid facerēs

I asked what you were doing

Tip: Ask first: "is the main verb in the present-zone or the past-zone?" That single answer locks in your two subjunctive options before you choose between them.

Quick Check

In Caesar's sentence Diū cum esset pugnātum, nostrī potītī sunt ("after they had fought a long time, our men gained possession"), why is esset pugnātum pluperfect subjunctive instead of perfect?

Study Tips

•Burn the four-cell grid into memory: primary main → present subj. (incomplete) or perfect subj. (completed); secondary main → imperfect subj. (incomplete) or pluperfect subj. (completed).
•When you see an imperfect subjunctive, refuse to translate it as English past simple. Try "was V-ing" or "would V" first — that's almost always the right reading.
•Diagnose the main verb FIRST. Pres./fut./fut. perf. = primary; impf./perf./pluperf. = secondary. Everything else follows from that one decision.
•Watch for the historical present and the historical infinitive in Caesar — both behave as past tenses for sequence purposes even though they look present.
