Relative Clauses of Cause and Concession | Latin Grammar

A Latin relative clause can carry an adverbial relation in addition to describing its antecedent. With the subjunctive, quī may mean “since he,” “because she,” or “although they.” The relative word still refers to an antecedent and still has a case role inside its own clause, but the clause as a whole explains the cause of the main statement or concedes a circumstance against which it remains true.

These uses are especially at home in (formal Classical prose) and oratory. English normally makes the relation explicit with “since,” “because,” or “although”; Latin can let the relative pronoun and subjunctive do both jobs. The mood marks the speaker’s framing of the clause, not uncertainty and not an automatic English “would.”

Three readings of a relative clause

Reading	Typical mood	Useful paraphrase	Discourse relation
identifying/descriptive	indicative	“who in fact ...”	identifies or adds a fact
causal	subjunctive	cum is ..., “since he ...”	explains the main clause
concessive	subjunctive	quamquam is ..., “although he ...”	grants an apparent obstacle

Tē laudō, quī prōmissum servāvistī.

I praise you, who kept your promise. (indicative: an added fact)

Tē laudō, quī prōmissum servāverīs.

I praise you, since you have kept your promise. (causal relative)

The visible contrast servāvistī/servāverīs changes how the relative material attaches to laudō. In the indicative sentence the speaker appends a factual description. In the subjunctive sentence the keeping of the promise is presented as the reason for the praise. Both translations can sound similar in English, so preserve the structural distinction while parsing even when idiomatic translation softens it.

Causal relatives: “since the antecedent ...”

A causal relative typically refers to an already identifiable antecedent and gives the speaker’s reason for the main assertion. The emphatic combinations quippe quī “inasmuch as he, since of course he” and ut quī “as being one who” make the causal interpretation especially clear. Quippe quī belongs chiefly to (formal/literary) prose; plain quī is less explicitly marked.

Lūciae grātiās agimus, quae nōbīs tam celeriter responderit.

We thank Lucia, since she has replied to us so quickly.

Mārcus tacuit, quippe quī nihil certī scīret.

Marcus kept silent, since of course he knew nothing for certain.

Eī facile persuāsistī, ut quī iam idem cōnsilium probāret.

You easily persuaded him, since he was already inclined to approve the same plan.

In the last sentence, ut quī does not introduce comparison “as who.” It presents the antecedent as someone whose existing disposition explains the result. This combination is marked (formal) and should not be forced into everyday beginner composition.

An authentic Ciceronian exclamation gives praise and its cause in a single relative clause. The quotation retains source spelling without editorial macrons:

O fortunate adulescens, qui tuae virtutis Homerum praeconem inveneris!

O fortunate young man, since you found Homer as the herald of your valor! (Cicero, Pro Archia 24; source spelling reproduced.)

Perfect subjunctive invēnerīs in a quantity-marked analysis is anterior to the speaker’s exclamation: Alexander is fortunate because he found such a herald. Translating “who would have found” would invent a conditional meaning absent from the sentence. The apostrophe is highly (oratorical/literary), but the causal syntax is regular Classical usage.

Concessive relatives: “although the antecedent ...”

A concessive relative grants a fact or circumstance that might have led one to expect the opposite main result. The main clause often contains tamen “nevertheless,” which is not required but is a powerful diagnostic. The subjunctive packages the relative clause as the conceded background.

Mārcus, quī fessus esset, tamen amīcōs adiūvit.

Marcus, although he was tired, nevertheless helped his friends.

Haec rēs, quae parva videātur, tamen magnum perīculum affert.

This matter, although it may seem small, nevertheless brings great danger.

English “may seem” is idiomatic here, but videātur does not assert uncertainty. The speaker grants the appearance for argumentative purposes. “Although it seems small” is equally faithful.

Concession is inferred from the clash between the relative content and the main statement. Without tamen or clear contextual opposition, a bare relative subjunctive may admit a causal or characteristic interpretation. That ambiguity is real. Good reading weighs discourse logic rather than assuming that every quī plus subjunctive carries one fixed label.

Tū, quī mē saepe reprehenderēs, nunc tamen idem facis.

Although you used to criticize me often, you now do the same thing.

The historic imperfect reprehenderēs represents repeated conduct set against nunc tamen idem facis. It does not mean “you would criticize me” unless a wider conditional context independently supplies that meaning.

Pronoun case and antecedent agreement remain ordinary

Adverbial force does not suspend relative morphology. The pronoun takes gender and number from its antecedent, then case from its role in its own clause.

Tibi crēdō, cui haec omnia nota sint.

I trust you, since all these things are known to you.

Here cui is masculine or feminine singular because it refers to tibi, and dative because nota sint takes a dative of the person to whom something is known. The whole clause gives the reason for trusting. Replacing cui with nominative quī would leave the predicative construction without its required dative.

Mīlitēs, quōs dux ipse ēlēgisset, tamen fūgērunt.

The soldiers, although the commander himself had selected them, nevertheless fled.

Accusative quōs is the object of ēlēgisset; nominative mīlitēs is only its antecedent. Pluperfect subjunctive marks the selection as prior to historic fūgērunt. The concession lies in the expectation that hand-picked soldiers would stand firm.

Tense and sequence

Causal and concessive relatives generally follow dependent sequence. Primary contexts use present for same/later time and perfect for anterior time; secondary contexts use imperfect and pluperfect respectively.

Main viewpoint	Same time	Earlier
primary	quī sciat	quī didicerit
secondary	quī scīret	quī didicisset

Eam rogō, quae rem bene intellegat.

I ask her, since she understands the matter well.

Eam rogāvī, quae rem anteā didicisset.

I asked her, since she had learned the matter earlier.

The first clause explains a present choice; the second explains a past choice by a still earlier acquisition of knowledge. Authors may preserve a natural or vivid tense in (literary) narration, but sequence remains the default for composition.

💡

A perfect subjunctive after a primary governor and a pluperfect after a historic governor can both express an earlier cause. Preserve the time relation; do not assign “may have” or “would have” mechanically.

Negation and scope

Use nōn, nēmō, nihil, or another ordinary negative inside causal and concessive relatives. Purpose nē is not their normal negator.

Eum nōn accūsō, quī vēritātem nōn cēlāverit.

I do not accuse him, since he has not concealed the truth.

Two negatives operate at different levels: nōn accūsō negates the main act, while nōn cēlāverit describes the causal fact. A concessive version could say eum accūsō, quī vēritātem nōn cēlāverit, tamen quod ..., but context must establish what concession is being granted. Do not treat negative polarity as a substitute for discourse logic.

Distinguishing causal relative from causal quod

Both can answer “why?”, but their architecture differs. A causal relative contains a relative word with an antecedent and a syntactic role inside its clause. Causal quod is a conjunction and has no case, gender, or number.

Lūciam laudāmus, quae vēritātem dīxerit.

We praise Lucia, since she has told the truth. (quae is the subordinate subject and refers to Lucia)

Lūciam laudāmus quod vēritātem dīxit.

We praise Lucia because she told the truth. (quod is a causal conjunction)

The second indicative presents the reason as the speaker’s fact. Causal quod may take a subjunctive when the reason is attributed, rejected, or otherwise represented through another viewpoint; see Quod, Quia, and Quoniam Causal Clauses.

Parsing procedure

Locate the antecedent and determine the relative word’s case inside its clause.
Identify indicative or subjunctive; do not translate it as “would” yet.
Test the plain descriptive reading: does the clause merely identify or add a fact?
Test causal paraphrase “since the antecedent ...” and concessive paraphrase “although the antecedent ....”
Look for quippe, ut quī, tamen, or an expectation-defying main clause.

💡

A causal relative supports the main claim; a concessive relative creates an expectation that the main claim overrides. The subjunctive is shared, so the direction of the argument decides between them.

Common Mistakes

Choosing subjunctive simply because the referent is uncertain

❌ Fortasse Lūcia est quae mē herī vocāverit.

Incorrect if yesterday’s call is offered as an identifying fact; fortasse alone does not make the relative causal.

✅ Fortasse Lūcia est quae mē herī vocāvit.

Perhaps Lucia is the person who called me yesterday.

Translating every subjunctive with “would”

❌ Tē laudō, quī vēritātem dīxerīs = ‘I praise you, who would have told the truth.’

Incorrect — no condition licenses ‘would have.’

✅ Tē laudō, quī vēritātem dīxerīs = ‘I praise you because you told the truth.’

The causal relation supplies natural English ‘because.’

Missing the concessive signal in the main clause

❌ Paula, quae aegra esset, tamen vēnit = ‘Paula came because she was ill.’

Incorrect in this context — tamen marks illness as an obstacle, not a cause of coming.

✅ Paula, quae aegra esset, tamen vēnit = ‘Although Paula was ill, she nevertheless came.’

The expectation-defying relation is concessive.

Giving the relative pronoun its antecedent’s case

❌ Annae grātiās agō, cui mihi auxilium tulerit.

Incorrect — dative cui copies Annae’s main-clause case, but the relative pronoun must be the subject of tulerit.

✅ Annae grātiās agō, quae mihi auxilium tulerit.

I thank Anna, since she brought me help.

The correction shows both rules: the antecedent supplies feminine singular agreement, while the subordinate subject role supplies nominative case.

Key Takeaways

Relative clauses of cause and concession combine ordinary relative morphology with an adverbial relation to the main clause. The subjunctive frames a reason or conceded circumstance; quippe quī strengthens a causal reading, while tamen often confirms concession. Case comes from the relative clause, tense normally follows sequence, and ordinary negation uses nōn. Translate the argument’s relation, not the subjunctive as an automatic “would.”
