Wh-Questions: chi, cosa, dove, quando, come, perché

A wh-question asks for specific information: who did it, what happened, where it took place, when it happened, how it was done, why the speaker is asking. Italian forms these questions on a clean, consistent template: wh-word + verb + (subject + the rest). The question word goes to the front, the verb follows immediately, and the subject — if expressed at all — comes after. There's no auxiliary like English do/does, and there's a hard rule that prepositions never get stranded at the end the way they do in English. Once you internalize the front-the-wh-word reflex, asking these questions feels almost mechanical.

This page covers the full inventory of wh-words, the four prepositional patterns (con chi, di cosa, da dove, per quanto), the three interchangeable forms of "what," the indirect-question patterns, and the most common transfer errors English speakers make.

1. The core wh-words

Italian has a compact set of question words, each occupying a clear semantic slot.

These eight items cover almost everything you'll want to ask. The first four — chi, cosa, quale, quanto — are pronouns and have their own page; see Interrogative Pronouns. The last four — dove, quando, come, perché — are interrogative adverbs and pure question words.

2. The basic structure: wh-word + verb + (subject)

The template for an Italian wh-question is straightforward:

Wh-word + Verb + (Subject) + (Rest of clause)

The subject is normally pro-dropped. When expressed, it comes after the verb.

When you do express the subject, it sits after the verb:

This is one of the few cases in Italian where the subject must appear after the verb — fronting the subject before the wh-word would be ungrammatical (Marco cosa fa? — marked, more colloquial; standard is Cosa fa Marco?).

3. Prepositions before wh-words: pied-piping

Italian doesn't allow preposition stranding. Whenever a preposition is involved, it must travel with the wh-word to the front of the clause.

People — preposition + chi

Things — preposition + cosa / che cosa

Places — preposition + dove

The preposition dove + a (going to) is normally just dove: Dove vai? (Where are you going?). The destination preposition is absorbed into the verb's own argument structure (andare a), so you don't need A dove vai? — though that form does exist, especially when emphasising the destination angle.

What you must NEVER do

The following English-style stranded patterns are ungrammatical in Italian:

For more on this rule and all its consequences, see Preposition Stranding.

4. Compound wh-questions

Italian has a number of fixed multi-word interrogative phrases that combine prepositions, wh-words, and nouns.

The distinction between da quanto tempo and per quanto tempo is worth noting: da points to a starting moment in the past for an ongoing situation (with present-tense verb), while per describes a completed bounded period (with past tense).

5. Che cosa / cosa / che — three ways to say "what"

Italian has three interchangeable forms for "what" in questions:

• Cosa — most common in everyday speech. Cosa fai?
• Che cosa — slightly more deliberate, neutral register. Che cosa fai?
• Che — shortest, also conversational, mostly with very common verbs. Che fai?

All three are correct, all three appear in writing, and all three slot into the same syntactic positions.

A regional note: cosa dominates the north and centre of Italy, che is more common in Tuscany and parts of the south, and che cosa is the safest middle-ground choice everywhere.

With prepositions, all three forms work, but cosa and che cosa feel smoother:

6. Wh-questions with compound tenses

When the verb is in a compound tense (passato prossimo, trapassato, etc.), the wh-word stays at the front and the auxiliary + participle follows together.

The structure is identical to questions in the present tense — only the verb form changes.

7. Indirect questions

When a question is embedded under another verb (verbs of asking, wondering, knowing, telling), it becomes an indirect question. The wh-word still goes at the front of the embedded clause.

A note on mood: in formal or literary contexts, the subjunctive can appear after verbs of wondering and asking in indirect questions. In modern everyday Italian, the indicative is fine. Mi chiedo dove sia (formal) and Mi chiedo dov'è (everyday) are both used — note that the apostrophe-elision rule still applies in writing.

8. Perché — both "why" and "because"

A peculiarity of Italian: perché serves both as the question word why AND as the answer-introducing conjunction because.

English needs two words (why / because); Italian uses one. This is a small but striking feature, and it's not confusing in context — the position in the sentence (clause-initial question vs reason-introducing) makes it clear.

A formal alternative for perché in the question sense is per quale motivo or per quale ragione:

This is the language of lawyers, journalists, and teachers — careful and slightly distancing. In casual speech, perché dominates.

9. Wh-questions with topicalization

You can combine a topicalized phrase with a wh-question by putting the topic before the wh-word, with a comma:

The topicalization frames what you're asking about. The comma is helpful in writing for the reader to see the prosodic pause.

10. Echo wh-questions

When you didn't catch a word and want it repeated, you can use an echo wh-question: keep the original sentence intact, but replace the missed word with a wh-word in the same position.

These echo questions keep the wh-word in situ rather than fronting it. They carry strong emotional shading — surprise, doubt, request for clarification — and are common in spoken Italian.

A subtle structural point: the in-situ wh-word in echo questions is the only position where a wh-word doesn't front in Italian. The standard fronting rule applies everywhere else.

11. Comparison with English

Italian and English wh-questions agree on the basic principle of fronting the wh-word, but they differ in two important ways.

English uses do/does/did support; Italian doesn't. "What does Marco do?" uses the auxiliary does; Italian "Cosa fa Marco?" uses just the verb. As with yes/no questions, this is a structural simplification in Italian.

English allows preposition stranding; Italian doesn't. "Who are you going with?" (with with at the end) is fully natural English; the corresponding Italian "Chi vai con?" is ungrammatical. Italian forces Con chi vai? — preposition fronted.

The two languages also differ on the position of the subject. In English wh-questions, the subject still goes between the auxiliary and the main verb (Where DID Marco GO?). In Italian, when the subject is expressed at all, it comes after the verb (Dove è andato Marco?) — and most of the time it's pro-dropped entirely (Dov'è andato? / Dov'è andato Marco?).

A compact summary of the patterns you'll use most:

Key takeaways

• Italian wh-questions front the question word and follow it with the verb. Subject, when expressed, comes after the verb.
• The core wh-words: chi, cosa / che cosa / che, quale, quanto, dove, quando, come, perché.
• Three forms of "what" — cosa, che cosa, che — are interchangeable; cosa dominates everyday speech.
• Prepositions front with the wh-word (pied-piping). Italian never strands: Con chi vai?, Da dove vieni?, A chi parli? — never Chi vai con? or Dove vieni da?
• Italian doesn't use do/does/did support — just the verb form is enough.
• Indirect questions keep the wh-word at the start of the embedded clause. Indicative is normal in modern speech; subjunctive is more formal.
• Perché does double duty as both "why" and "because" — Italian uses one word where English uses two.
• Dov'è with apostrophe is mandatory in writing — dove
  • è contracts obligatorily.
• The compound interrogative phrases (a che ora, da quanto tempo, per quale motivo) cover most of the more nuanced asking.
• The fronting reflex is the central skill — once it's automatic, you'll be asking accurate Italian questions without thinking.
