Subordinating Conjunctions in Italian

In Brief

Italian subordinating conjunctions join a main clause to a dependent clause—a group of words that cannot carry the full message on its own. Conjunctions presenting information as fact, such as siccome and dato che, normally take the indicative; conjunctions expressing purpose, concession, prevention, or an exception, such as affinché, benché, senza che, and a meno che, normally take the subjunctive.

Overview

Compare Continuo a lavorare (“I keep working”) with Benché sia stanco, continuo a lavorare (“Although I am tired, I keep working”). The conjunction benché turns sia stanco into a dependent clause and explains how that clause relates to the main statement: tiredness would normally be a reason to stop, but it does not change the result.

At B2, choosing a conjunction is not only about meaning. You must also choose the mood of the verb: the indicative presents an event as a fact or direct piece of information, while the subjunctive presents it through a viewpoint such as purpose, concession, possibility, or exception. A mood is simply a set of verb forms that shows how the speaker frames an action. The conjunction often determines the mood more strongly than the English translation does.

This matters because English frequently uses an ordinary verb form where Italian requires a subjunctive. “Before you leave,” “although she is,” and “unless it rains” become prima che tu parta, sebbene lei sia, and a meno che non piova. Learning the conjunction together with its usual mood is therefore more reliable than translating one word at a time.

How It Works

A typical sentence has two parts:

main clause + conjunction + dependent clause

Ti scrivo + affinché + tu sappia tutto.
“I am writing to you so that you know everything.”

The dependent clause has its own verb and usually its own subject. It may come before or after the main clause. When it comes first, Italian normally places a comma after it: Benché fosse tardi, siamo rimasti.

Conjunctions normally followed by the indicative

The indicative is the ordinary mood used to report facts, events, and information treated as real.

Meaning	Conjunction	Typical use	Example
when	quando	time regarded as real or expected	Ti chiamo quando arrivo.
while / whereas	mentre	simultaneous events or contrast	Io cucinavo mentre lui leggeva.
because	perché	reason or cause	Resto perché sono stanco.
since / as	siccome	known or obvious cause, often before the main clause	Siccome piove, restiamo a casa.
given that / since	dato che	stated premise or cause	Dato che hai finito, possiamo uscire.

These conjunctions can occur with different indicative tenses. The tense expresses the time relationship:

• Quando ero piccolo, vivevo a Torino. — a past setting
• Quando è arrivata, abbiamo iniziato. — one completed event before another
• Quando arriverai, ne parleremo. — two future events

That last pattern differs from English. Standard English says “when you arrive,” not “when you will arrive,” but Italian can use the future after quando: quando arriverai. The present is also natural when the future event feels immediate or certain: Ti telefono quando arrivo.

Perché answers perché? (“why?”) when it introduces a cause. Do not confuse this use with purpose. Italian often uses affinché plus the subjunctive for an explicit, especially formal, “so that.”

Conjunctions normally followed by the subjunctive

The subjunctive is a verb mood used when a clause is framed through purpose, concession, uncertainty, a condition, or another non-neutral viewpoint.

Meaning	Conjunction	Relationship	Example
so that	affinché	purpose	Parlo lentamente affinché tutti capiscano.
although	benché, sebbene	concession: the result holds despite an obstacle	Sebbene sia tardi, rimango.
before	prima che	an event not yet realised relative to the main clause	Partiamo prima che inizi il traffico.
without	senza che	an action does not happen	È entrato senza che nessuno lo vedesse.
unless	a meno che (non)	exception to what is stated	Vengo, a meno che non debba lavorare.

The subject helps determine whether you need a full clause or an infinitive (the dictionary form of a verb, such as partire).

• Different subjects: Ti telefono prima che tu parta. — “I’ll call you before you leave.”
• Same subject: Ti telefono prima di partire. — “I’ll call you before leaving.”
• Different subjects: È uscito senza che io lo sapessi. — “He left without my knowing.”
• Same subject: È uscito senza salutare. — “He left without saying goodbye.”

With affinché, the two clauses normally have different subjects: Te lo dico affinché tu sappia. If the subject is the same, Italian usually prefers per + infinitive: Studio per imparare, not studio affinché impari.

Choosing the subjunctive tense

Italian generally follows sequence of tenses: the tense in the dependent clause shows whether its action is simultaneous with, earlier than, or later than the main action.

Main time frame	Relationship	Common subjunctive	Example
present or future	simultaneous/later	present subjunctive	Te lo spiego affinché tu capisca.
present or future	earlier/completed	past subjunctive	Benché abbia studiato, è nervoso.
past or conditional	simultaneous/later	imperfect subjunctive	Parlava piano affinché tutti capissero.
past or conditional	earlier/completed	pluperfect subjunctive	Benché avesse studiato, non superò l’esame.

The past subjunctive is formed with the present subjunctive of avere or essere plus a past participle (a form such as studiato or partito). The pluperfect subjunctive uses the imperfect subjunctive of the auxiliary: avesse studiato, fosse partito.

The special non after a meno che

A meno che commonly appears as a meno che non + subjunctive:

Usciremo, a meno che non piova. — “We’ll go out unless it rains.”

Here non is often expletive: it is grammatically conventional but does not reverse the meaning by itself. Do not translate it as an extra “not.” The version without non also occurs, but a meno che non is the safest pattern to learn.

Examples in Context

Italian	English	Note
Quando finirai il lavoro, chiamami.	When you finish the work, call me.	Italian allows the future after quando.
Mentre preparavo la cena, ascoltavo un podcast.	While I was making dinner, I was listening to a podcast.	Two simultaneous background actions.
Marta ama la città, mentre Paolo preferisce la campagna.	Marta loves the city, whereas Paolo prefers the countryside.	Mentre marks contrast.
Non vengo perché ho già un impegno.	I’m not coming because I already have plans.	A factual reason takes the indicative.
Siccome il treno era in ritardo, abbiamo preso l’autobus.	Since the train was late, we took the bus.	The cause is placed first.
Dato che conosci bene Roma, scegli tu il ristorante.	Since you know Rome well, you choose the restaurant.	A stated premise leads to the request.
Benché sia stanco, continuo a lavorare.	Although I’m tired, I keep working.	Present concession, present subjunctive.
Sebbene avessero poco tempo, visitarono il museo.	Although they had little time, they visited the museum.	Past narrative with imperfect subjunctive.
Te lo dico affinché tu sappia la verità.	I’m telling you so that you know the truth.	Purpose; the subjects differ.
Abbiamo ripetuto le istruzioni affinché tutti capissero.	We repeated the instructions so that everyone would understand.	Past purpose, imperfect subjunctive.
Spegni il forno prima che la torta si bruci.	Turn off the oven before the cake burns.	The subjects differ, so use prima che.
È uscito senza che io lo sapessi.	He went out without my knowing.	The omitted event takes the subjunctive.
A meno che non piova, usciremo.	Unless it rains, we’ll go out.	Conventional non does not mean “unless it doesn’t rain.”
Benché abbia dormito otto ore, mi sento ancora stanca.	Although I slept for eight hours, I still feel tired.	Earlier completed action, past subjunctive.

Common Mistakes

Using the indicative after a conjunction that requires the subjunctive

• Wrong: Benché è stanco, continua a lavorare.
• Right: Benché sia stanco, continua a lavorare.
• Why: Benché conventionally introduces a concession with the subjunctive. English “although he is” gives no visible warning that Italian changes mood.

Dropping non because the English sentence is affirmative

• Less idiomatic: Usciremo, a meno che piova.
• Preferred: Usciremo, a meno che non piova.
• Why: Italian commonly includes an expletive non after a meno che. It does not add a second logical negation.

Using a full clause when both actions have the same subject

• Awkward: Esco prima che io ceni.
• Natural: Esco prima di cenare.
• Why: With the same subject, prima di + infinitive is normally shorter and more natural. Use prima che when the clauses have different subjects: Esco prima che tu ceni.

Copying English tense choice after quando

• Possible but different in tone: Ti chiamerò quando arrivo.
• Clear future sequence: Ti chiamerò quando arriverò.
• Why: Unlike English, Italian can use the future in the time clause. The present is also possible, especially for a scheduled or immediate event, but learners should not avoid the future merely because English does.

Confusing cause and purpose

• Wrong for the intended meaning: Parlo lentamente perché tutti capiscono. (“I speak slowly because everyone understands.”)
• Right: Parlo lentamente affinché tutti capiscano. (“I speak slowly so that everyone understands.”)
• Why: A cause explains why something happens; a purpose describes the intended result. Purpose takes affinché + subjunctive, or often per + infinitive when the subject is the same.

Choosing the present subjunctive after a past main verb

• Wrong in standard tense sequence: Ha parlato lentamente affinché tutti capiscano.
• Right: Ha parlato lentamente affinché tutti capissero.
• Why: A past main verb normally calls for the imperfect subjunctive for a simultaneous or later purpose in the past.

Usage Notes

Siccome is very common in both speech and writing. It normally introduces information treated as already known or obvious and often comes first: Siccome sei qui, iniziamo. Placing it after the main clause can sound less natural than using perché: Iniziamo perché sei qui.

Dato che is neutral and useful in conversation, explanation, and argument. Poiché also means “since/because” but is more characteristic of careful or formal writing. All three normally take the indicative when they present a cause as fact.

Benché and sebbene are close in meaning and both belong comfortably to written and careful spoken Italian. Everyday speech often prefers anche se, usually with the indicative when the fact is accepted: Anche se sono stanco, esco. This does not make the subjunctive after benché optional in standard Italian.

Affinché is precise but can sound formal in casual conversation. Speakers often use perché + subjunctive for purpose: Te lo spiego perché tu possa decidere. Where the subject stays the same, per + infinitive is much more usual: Te lo spiego per aiutarti.

Beyond the Basics

Mood choice can sometimes reflect meaning rather than a rigid word list. Time conjunctions such as quando normally take the indicative for actual or expected events, but a subjunctive can appear when the time is indefinite or embedded in a context of uncertainty: Non so quando possa arrivare (“I don’t know when he may arrive”). Here the uncertainty comes from non so, not from quando alone.

Some conjunctions have a similar negative non: finché non, “until,” often contains an expletive negative. Aspetta finché non torno means “Wait until I return,” not “wait while I do not return.” This construction usually takes the indicative when the return is expected, although context can affect mood.

Concession also has several stylistic alternatives:

Form	Usual mood	Typical register or nuance
benché, sebbene	subjunctive	neutral-careful to formal
nonostante, malgrado + clause	subjunctive	concise, common in writing
anche se	often indicative	very common in speech; presents the fact directly
per quanto	subjunctive	“however/no matter how,” often with an adjective or adverb

Compare Sebbene sia costoso, lo compro with Anche se è costoso, lo compro. Both mean “Although it is expensive, I’m buying it,” but the second sounds more conversational and asserts the expense more directly.

Finally, word order changes emphasis. A dependent clause first sets the frame for what follows: Sebbene fosse tardi, continuarono a parlare. Putting it last highlights the unexpected qualification: Continuarono a parlare, sebbene fosse tardi. The grammar is the same, but the flow of information is different.

Practice Tips

1. Learn chunks, not isolated translations. Make pairs such as siccome + indicative, benché + subjunctive, prima che + subjunctive, and prima di + infinitive. Say one complete example with each pair.
2. Transform same-subject sentences. Start with Parto senza salutare, then change the subject: Parto senza che lui mi saluti. Repeat with prima di/prima che and per/affinché.
3. Build a tense ladder. Rewrite one purpose sentence in four time frames: affinché capisca, affinché abbia capito, affinché capisse, affinché avesse capito. This links conjunction choice to subjunctive tense rather than practising them separately.
