Adolescence is a period of life that every person goes through. It is a time of transition from childhood to adulthood and is characterized by physical, emotional, and social changes. Synonyms for adolescence include teenage years, youth, puberty, adolescence years, and teenagehood. These words describe the stage of life when a person is no longer a child, but not yet mature enough to be considered an adult. Other synonyms for adolescence could include the term "young adulthood" as it reflects the transitional phase a person experiences as they take on greater responsibilities, gain independence, and start shaping their own future.
