✦Grammar Breakdown
Quandosonoiniziatiituoisintomi?
Quando (interrogative adverb)
‘Quando’ introduces a time‑related question and stays at the beginning of the sentence.
Passato prossimo with ‘essere’
‘Iniziare’ can be used intransitively, so the auxiliary verb is ‘essere’; the past participle ‘iniziati’ agrees in gender and number with the subject ‘i sintomi’.
Agreement of the past participle
Because the subject ‘i sintomi’ is masculine plural, the participle takes the ending –ati.
Possessive adjective placement
In Italian the possessive adjective (tuoi) follows the article (i) and agrees in gender and number with the noun.
Question formation
Italian questions often keep the declarative word order; intonation or a question mark signals that it is a question.

✕Common Mistakes
Quando hai iniziato i tuoi sintomi?
‘Iniziare’ uses ‘essere’ as the auxiliary when it is intransitive; ‘hai iniziato’ is incorrect for symptoms.
Quando sono iniziati tu sintomi?
The possessive adjective must be preceded by the definite article (i tuoi sintomi).
Quando è iniziato i tuoi sintomi?
The past participle must agree with the subject; ‘iniziato’ (masc. sing.) would be wrong for ‘i sintomi’.

Cultural Tip
In Italy doctors usually address patients with the formal ‘Lei’. The formal version of the phrase is ‘Quando sono iniziati i suoi sintomi?’ Using the formal pronoun shows respect, especially with older patients or in a first‑time consultation. In casual conversation among friends, the informal ‘tuoi’ is perfectly acceptable.
