Italian Questions: Complete Guide

This page is the cheat-sheet for the Italian question system. It pulls together what is otherwise scattered across the dedicated subpages — the inventory of question words, their inflection patterns, the syntax of yes/no and wh-questions, tag questions, indirect questions, and the mood that follows them — into a single reference you can scan when you're not sure which interrogative to reach for.

For the conceptual overview of how Italian asks questions, start with Italian Questions: Overview. This page is the lookup table you keep open beside it.

1. Yes/no questions: intonation alone

A yes/no question in Italian has the same word order as the corresponding statement — only the rising intonation (in speech) or the question mark (in writing) marks it as a question.

The verb does not move. The subject (when expressed) typically goes after the verb in questions where another element is fronted, but in plain yes/no questions there is usually no subject pronoun at all — Italian is pro-drop, and the verb ending tells you who the subject is.

For the full coverage including post-verbal subjects and confirmation responses, see Yes/No Questions.

2. The interrogative inventory

Italian has eight core question words. Most are invariable; only quale/quali (number) and quanto/quanta/quanti/quante (gender + number) inflect.

The following sections walk through each one with a representative example or two, and flag the orthographic and structural traps.

Chi — "who / whom"

Refers to people only. Invariable. Used both as subject and object. Combines freely with prepositions.

The English distinction who/whom does not exist in Italian: chi covers both subject and object uses. Italian also requires the preposition to lead — there is no preposition stranding (who did you come with? in Italian is always con chi sei venuto?, never chi sei venuto con?).

Cosa / che cosa / che — "what"

Three interchangeable forms with shifts in register:

• Cosa is the most colloquial and most common in spoken Italian.
• Che cosa is the neutral, slightly more careful form.
• Che alone is the shortest and is common in casual speech.

In context, all three forms are equivalent. Choose based on register: cosa for everyday speech, che cosa for slightly more formal contexts, che when speed matters.

Quale / quali — "which"

Picks from a defined set of options. Inflects only for number, not gender: singular quale covers both masculines and feminines; plural quali does the same.

The qual è form (no apostrophe) is one of the most-tested orthographic points in Italian schools. Writing qual'è is wrong: qual is a truncation, not an elision, so no apostrophe is needed. See Quale: Which for the full explanation.

Quanto / quanta / quanti / quante — "how much / how many"

The most heavily inflected of the question words. Agrees with the noun in both gender and number when used with a count or mass noun. Invariable as an adverb when modifying a verb (Quanto costa? "How much does it cost?").

The agreement is mandatory. Saying Quanto persone or Quante anni is a clear error.

Dove — "where"

Invariable. Combines with prepositions (da dove "from where", fino a dove "up to where"). Has the elided form dov'è before the verb è.

The contrast between dov'è (apostrophe, elision) and qual è (no apostrophe, truncation) is one of the genuinely subtle points of Italian orthography. Dove drops a vowel before another vowel — an elision — and the apostrophe marks it. Quale shortens to qual by truncation, which leaves no missing vowel for the apostrophe to mark.

Quando — "when"

Invariable. Combines with prepositions: da quando "since when", fino a quando "until when".

Perché — "why" (and "because")

Invariable, always written with the acute accent é (not grave è — this is the most-tested accent in Italian). Has a famous double life: it is both the question word "why" and the answer-introducer "because".

The reason for the dual function is etymological — perché descends from Latin per quid, "for what (reason)", which serves both to ask the reason and to introduce it. Italian writers occasionally use poiché or siccome in declarative use to disambiguate ("since"), but in everyday speech perché does both jobs.

Come — "how"

Invariable. Has the elided form com'è before è.

The phrase com'è (apostrophe, elision) follows the same pattern as dov'è — and again, the contrast with qual è (no apostrophe, truncation) is the trap.

3. Wh-question word order

For wh-questions, the structure is interrogative + verb + (subject). The subject, if expressed at all, typically follows the verb.

Putting the subject before the verb is grammatical but unidiomatic in a neutral question — Marco cosa mangia? shifts focus onto Marco and sounds slightly emphatic. The neutral order has the subject after the verb.

Prepositions before wh-words

Italian does not strand prepositions. The preposition always leads.

This is the same pattern as in formal English (With whom did you go? rather than Who did you go with?). Italian uses it in all registers, formal and informal alike.

4. Tag questions

Tag questions in Italian are invariable particles appended to a statement. Three are common:

The crucial difference from English is that Italian tag questions are invariable. English forces the tag to agree with the main verb in tense, polarity, and subject (You're Italian, aren't you? / You weren't there, were you? / She'll come, won't she?). Italian just sticks one of no?, vero?, giusto? on the end and is done.

5. Indirect questions

When a question is embedded inside another sentence, three things change:

1. The question mark disappears (unless the outer sentence is itself a question).
2. The rising intonation disappears.
3. The verb may shift mood — to subjunctive in formal registers, especially after verbs of doubt or wondering.

The mood selection is a question of register and the speaker's attitude. The subjunctive marks uncertainty or genuine wondering; the indicative reports the embedded question more matter-of-factly. In modern colloquial Italian, the indicative is increasingly accepted in all such contexts. In formal writing, the subjunctive remains the educated norm.

For the full mood-selection rules in indirect questions, see Indirect Questions.

Se for indirect yes/no questions

When the embedded question is a yes/no question (rather than a wh-question), Italian uses se "if/whether" as the connector:

The verb after se takes the indicative or subjunctive depending on register, in the same pattern as wh-clause indirect questions.

6. Punctuation: one mark, at the end

Italian uses a single question mark at the end of the sentence. There is no inverted question mark at the start (that is Spanish). There is no double space before the mark (that is French).

For multi-clause sentences with embedded questions, only the outer interrogative clause takes the question mark:

The outer clause (Mi dici) is what makes the whole sentence a question; the embedded come si arriva alla stazione is reported, not asked, so no mark goes there.

7. Quick decision tree

When you're not sure which question word to reach for, walk through these:

If the question is governed by a preposition (to whom, from where, with what), put the preposition first, then the question word.

8. A worked dialogue: the whole system in action

Here is a short conversation that uses every type of question discussed on this page.

The dialogue contains nine questions in nine turns: yes/no by intonation, wh- with most of the question words, indirect with both indicative and subjunctive, prepositional fronting, two tag questions, and the qual è form. Every one of them follows the patterns laid out above.

Common Mistakes

Key takeaways

• Yes/no questions are formed by intonation alone — no auxiliary, no inversion, no movement.
• The eight core interrogatives are chi, cosa/che cosa/che, quale/quali, quanto/quanta/quanti/quante, dove, quando, perché, come.
• Only quale (number) and quanto (gender + number) inflect.
• Perché takes the acute accent (é). Writing perchè with a grave accent is a common error.
• Qual è is written without an apostrophe. Writing qual'è is wrong — qual is a truncation, not an elision.
• Dov'è and com'è ARE written with apostrophes — those are genuine elisions of dove and come before è.
• Italian does not strand prepositions. Con chi parli?, Da dove vieni?, A cosa pensi? — the preposition always leads.
• Tag questions are invariable. No?, vero?, giusto? attach to any statement regardless of tense or polarity.
• Indirect questions drop the question mark and the rising intonation, and may shift the verb to subjunctive in formal registers.
