Attraction of Mood | Latin Grammar

Attraction of mood occurs when a clause that might have had an indicative as an independent factual comment appears in the subjunctive because it is tightly embedded in a larger subjunctive or infinitive thought. The term describes a tendency, not a mechanical rule: Classical Latin keeps the indicative when the embedded clause remains the writer's own factual aside.

This pattern belongs especially to (formal) and (literary) periodic prose. English usually gives no visible sign of the attraction, so an English-speaking reader must first map the Latin dependencies and only then translate.

The Structural Core

Consider a relative clause inside another relative clause of characteristic:

Nēmō tam avārus est cui quod habeat satis sit.

No one is so greedy that what he has is enough for him.

The outer cui … satis sit characterizes a type and therefore has sit. The inner quod habeat, “what he has,” is part of the content judged insufficient. Its subjunctive habeat is attracted into the mood of that integrated thought. If the speaker detaches the possession as a fact, an indicative is possible:

Nēmō tam avārus est cui quod habet satis sit.

No one is so greedy that what he in fact has is enough for him.

The difference is not normally dramatic in English. The indicative habet gives the narrator greater responsibility for “he has it”; the attracted subjunctive habeat packages that proposition inside the characterization. Context, not the ending alone, licenses this reading.

💡

Attraction does not mean “a nearby subjunctive infects another verb.” The clauses must form one semantic unit. Coordination, parenthesis, and the writer's own explanatory facts can break the dependency.

Environment	Likely mood in the inner clause	Interpretation
Inner clause integral to a subjunctive clause	Subjunctive often attracted	One complex, represented thought
Inner clause integral to an infinitive phrase	Subjunctive often attracted	The noun and its qualification form the unit
Writer's parenthetical fact	Indicative normally retained	Comment asserted from outside
Clause already requires subjunctive independently	Subjunctive	Purpose, result, characteristic, oblique speech, and so on

Attraction under a Subjunctive

A purpose, result, characteristic, or other subjunctive clause can contain a further temporal, conditional, or relative clause. Attraction is easiest to recognize when that inner clause would ordinarily be factual.

Lēgātum mīsit ut, postquam hostēs advēnissent, pācem peteret.

He sent an envoy to seek peace after the enemy had arrived.

The purpose is ut … pācem peteret. Since postquam ordinarily introduces an indicative factual time clause, subjunctive advēnissent clearly packages the arrival inside the purpose conceived by the sender. It follows the historical sequence of that represented plan rather than asserting the arrival separately as the narrator's intervention.

Rogāvit quid facerem sī nūntius venīret.

He asked what I would do if a messenger came.

Here facerem marks an indirect question, while sī … venīret is an inseparable condition on the contemplated action. Its subjunctive is expected from the hypothetical meaning as well as from embedding; such overlap is common. Do not label every nested subjunctive “attraction” when purpose, condition, characteristic, or indirect discourse already explains it fully.

An authentic Classical example shows the integration particularly clearly:

nemo avarus adhuc inventus est cui quod haberet esset satis

No miser has yet been found for whom what he had was enough. — Cicero, Paradoxa Stoicorum 52

The quotation keeps its source spelling without editorial macrons. Esset belongs to the outer clause of characteristic; haberet is nested inside it. The miser's possessions are presented as part of the same generalized description, not as a separately vouched-for fact.

Attraction under an Infinitive

An infinitive has no indicative/subjunctive contrast of its own, but a finite clause embedded inside a tightly unified infinitive phrase may take the subjunctive. The attraction here is to the infinitive's dependent status, not to a visible subjunctive ending.

Mōs erat laudārī eōs quī prō patriā cecidissent.

It was customary for those who had fallen for their country to be praised.

The object eōs and the defining relative quī … cecidissent jointly identify the people praised. An indicative ceciderant could instead present their fall as the writer's own factual specification, but the subjunctive makes the whole expression “to praise the fallen” a single conceptual object.

Difficile est invenīre librum quī omnia quae quaerās explicet.

It is difficult to find a book that explains everything you may look for.

Quī … explicet is independently characteristic after an indefinite antecedent; quae quaerās is nested within that imagined specification. Since both clauses describe the sought type rather than an identified book and a known list of questions, the subjunctives cohere.

Attraction and Indirect Discourse

Traditional grammars sometimes use “attraction” broadly for subjunctives embedded under an infinitive in reported speech. It is clearer to separate the regular rule of subordinate clauses in indirect discourse from optional assimilation elsewhere. A subordinate proposition belonging to the original speaker normally becomes subjunctive in ōrātiō oblīqua.

Dux dīxit mīlitēs, ubi signum datum esset, impetum factūrōs esse.

The commander said that the soldiers would attack when the signal had been given.

The accusative-and-infinitive is mīlitēs … impetum factūrōs esse. The ubi clause belongs to the commander's forecast, so datum esset marks it as represented rather than asserted by the narrator.

By contrast, an indicative can deliberately step outside the reported viewpoint:

Dux dīxit mīlitēs Vesontiōnem, quod est oppidum maximum Sēquanōrum, petere.

The commander said that the soldiers were heading for Vesontio, which is the largest town of the Sequani.

Est is a parenthetical fact supplied by the narrator. It is grammatically inside the sentence but pragmatically outside the commander's report. This is why punctuation and translation alone cannot diagnose mood; one must ask whose assertion the clause is.

Sequence Still Applies

Once attraction has selected the subjunctive, tense follows the normal relationship of sequence and relative time. A primary governing perspective favors present for simultaneous or subsequent action and perfect for prior action; a historical perspective favors imperfect and pluperfect.

Quaerit quid agās cum Rōmam veniās.

He asks what you are doing when you come to Rome.

Quaesīvit quid agerēs cum Rōmam vēnissēs.

He asked what you were doing when you had come to Rome.

The second sentence does not use pluperfect merely because “attraction requires it.” Vēnissēs marks arrival prior to the contemporaneous agerēs within historical sequence. See Sequence of Tenses for the full system.

A Reliable Parsing and Production Test

Work outward from the smallest finite clause.

Identify its own conjunction, subject, objects, and semantic type.
Ask whether purpose, result, characteristic, condition, or indirect discourse already licenses the subjunctive.
Find the clause or infinitive on which it depends; do not use linear proximity as a substitute for structure.
Test whether the inner claim is integral to that represented thought or is the narrator's detachable fact.
Only then call an otherwise unexplained subjunctive “attracted,” and determine its tense from sequence and relative time.

For composition, attraction is rarely obligatory enough to justify forcing it into every nested clause. In neutral learner prose, preserve an indicative fact when you mean to endorse it independently; use the subjunctive when the qualification belongs inside a contemplated, characterized, or reported unit.

Common Mistakes

Copying English clause order instead of tracing dependencies

❌ Dux dīxit mīlitēs impetum faciunt ubi signum datum est.

Incorrect — the reported assertion requires an accusative and infinitive, and the time clause belonging to that report requires the subjunctive.

✅ Dux dīxit mīlitēs, ubi signum datum esset, statim impetum factūrōs esse.

The commander said that the soldiers would attack at once when the signal had been given.

The English position of “when” does not determine the Latin mood. The ubi clause depends on the reported infinitive.

Treating every nested subjunctive as attraction

❌ Mīsit quī auxilium petēbat.

Incorrect for the intended purpose ‘he sent someone to ask for help’ — the indicative merely describes someone who was already asking.

✅ Mīsit quī auxilium peteret.

He sent someone to ask for help.

Changing an authorial aside into reported information

❌ Dīxit sē Rōmam, quae Italiae caput esse, proficīscī.

Incorrect — an authorial relative aside needs a finite indicative, not a second infinitive.

✅ Dīxit sē Rōmam, quae Italiae caput est, proficīscī.

He said that he was setting out for Rome, which is the capital of Italy.

Choosing tense by visual imitation

❌ Quaesīvit quid agerēs cum Rōmam veniās.

Incorrect in ordinary historical sequence — present veniās clashes with the past viewpoint.

✅ Herī quaesīvit quid agerēs cum Rōmam vēnissēs.

Yesterday he asked what you were doing when you had arrived in Rome.

Key Takeaways

Attraction packages an embedded clause into the mood and viewpoint of a larger dependent thought.
It is favored by semantic integration, not merely by adjacency to a subjunctive.
An indicative can be retained to mark the writer's independent factual comment.
First identify every head and dependency; then choose mood, sequence, and translation.
