Past participle agreement (lavato)
The past participle agrees with the subject in gender and number – ‘lavato’ for a male speaker, ‘lavata’ for a female.

✕Common Mistakes
Hai lavato i denti?
Reflexive verbs use ‘essere’ as the auxiliary, not ‘avere’.
Ti sei lavata i denti?
If the speaker is male, the past participle must be masculine (lavato).
Sei ti lavato i denti?
The reflexive pronoun ‘ti’ must stay before the auxiliary; placing it after changes the meaning.

Cultural Tip
In Italy, ‘lavarsi i denti’ is perfectly correct, but most people say ‘spazzolarsi i denti’ because a toothbrush is the usual tool. When speaking to children, adults often ask this question as part of a bedtime routine. Remember to match the past participle to your own gender – a female speaker would say ‘Ti sei lavata i denti?’.
