What is your name?
CHIA-ma — the 'chi' sounds like 'ki'. Stress on first syllable.
Ask when meeting someone formally. 'Come si chiama?' uses the formal 'si' form. In informal contexts, 'come ti chiami?' is used. Always use the formal with strangers until invited to informality.
Italian names follow specific patterns: first name ('nome di battesimo' = baptism name), family name ('cognome'). In formal address, use 'Signor + cognome' or 'Signora + cognome'. Never use a first name with someone you've just met formally unless invited. Titles (Dottore, Professore, Ingegnere) are used frequently.
Come ti chiami?

For people your own age or younger in social contexts.

Standard self-introduction — 'mi chiamo' = I am called.
Piacere di conoscerla.
Pleased to meet you (formal).
The formal version — for 'Lei' register contexts.
Italian professional titles are used with great frequency. A doctor is 'Dottore/Dottoressa' even in casual conversation; an engineer is 'Ingegnere'; a lawyer 'Avvocato'. Even university graduates are sometimes called 'Dottore' as a sign of respect. Using someone's title correctly signals cultural awareness.
