Why adolescence is also called teenage?

Explanation

**Step-by-Step Solution:**

1. **Definition of Adolescence**: Adolescence is a developmental stage that typically begins around the age of 11 and lasts until about 18 or 19 years old. It is a period of significant physical, emotional, and social changes.

2. **Definition of Teenage**: The term "teenage" specifically refers to the ages from 13 to 19. This is derived from the fact that the numbers for these ages end with the suffix "-teen" (thirteen, fourteen, fifteen, etc.).

3. **Overlap of Ages**: The age range for adolescence (11 to 19 years) overlaps with the teenage years (13 to 19 years). This means that while all teenagers are adolescents, not all adolescents are teenagers.
