Verb 'tener' for age
In Spanish, age is expressed with the verb 'tener' (to have) followed by the number and the noun 'años'.

✕Common Mistakes
Tengo 40 años de vida.
Adding 'de vida' is redundant; 'tengo 40 años' already means you are 40 years old.
Tengo 40 años viejo.
Do not attach the adjective 'viejo' after the age; it sounds unnatural.
Tengo cincuenta años.
Make sure the number matches the intended age; saying 'cincuenta' means 50, not 40.

I am forty years old.
Tengo 40 años de edad.
I am 40 years old (more formal).
Cultural Tip
In many Spanish‑speaking countries, people often mention their age when meeting new acquaintances, especially in casual settings. However, older adults may consider it a private detail, so use discretion in formal or professional contexts. Also, avoid adding adjectives like 'viejo' after the age; the age alone conveys the information.
