Vecchio vs. anziano
The Italian language has two common words for 'old': 'vecchio' and 'anziano'. While both refer to age, they have distinct uses and connotations.
Vecchio
'Vecchio' is a general term for old, often used for objects, ideas, or people in a more casual or potentially negative context.

Anziano
'Anziano' specifically refers to elderly people and is considered more respectful and formal.

Summary
While 'vecchio' is a versatile term for old things or people, potentially with negative connotations, 'anziano' is specifically used for elderly people in a more respectful manner. Use 'vecchio' for objects or informal situations, and 'anziano' when referring politely to older adults.
