Adolescence

1. The period of physical and psychological development from the onset of puberty to maturity.
2. A transitional period of development between youth and maturity: the adolescence of a nation.

Period of life from puberty to adulthood (roughly ages 12 – 20) characterized by marked physiological changes, development of sexual feelings, efforts toward the construction of identity, and a progression from concrete to abstract thought. Adolescence is sometimes viewed as a transitional state, during which youths begin to separate themselves from their parents but still lack a clearly defined role in society. It is generally regarded as an emotionally intense and often stressful period.[1]

The teenage years are from ages 13 to 19. However, the end of adolescence and the beginning of adulthood varies by country and by function, and furthermore even within a single nation-state or culture there can be different ages at which an individual is considered to be (chronologically and legally) mature enough to be entrusted by society with certain tasks. Such milestones include, but are not limited to, driving a vehicle, having legal sexual relations, serving in the armed forces or on a jury, purchasing and drinking alcohol, voting, entering into contracts, completing certain levels of education, and marrying.[2]

In short, adolescence is the time between the beginning of sexual maturation (puberty) and adulthood. It is a time of psychological maturation, which a person becomes "adult-like" in behavior.

Adolescence is roughly considered to be the period between 13 and 19 years of age. The adolescent experiences not only physical growth and change but also emotional, psychological, social, and mental change and growth.[3]
