The state of growing up from childhood to manhood or womanhood; youth, or the period of life between puberty and maturity, generally considered to be, in the male sex, from fourteen to twenty-one. Sometimes used with reference to the lower animals.
Stage of growth and development ranging from about 11 or 12 years old to 17 or 18 years old in which major physiologic, cognitive, and behavioral changes take place. According to some theorists, important developmental tasks need to be accomplished (e.g., developing an identity, becoming independent, etc.).
The period of transition from childhood to adulthood, describing both the development to sexual maturity and to psychological and relative economic independence. The World Health Organization uses the 10-19 year age range to define adolescence, with further divisions for early adolescence: 10-14 years, and late adolescence: 15-19 years.
Adolescence is the period of transition between puberty and adulthood. Adolescence is roughly considered to be the period between 12 and 19 years of age. It refers to the time between the beginning of sexual maturation (puberty) and adulthood. During this period, adolescents are expected to become capable of adult behaviour and response, and autonomous decision-making. Adolescents experience not only physical growth and change but also emotional, psychological, social and mental change and growth.
the period of time in a person's life beginning with the onset of puberty and ending with the full acceptance of adult responsibility. In years, that could be anywhere from age 10 on the low end to about age 25 on the other end.
Adolescence (Latin adolescentia, from adolescere, to grow up) is the period of psychological, social, and physical transition between childhood and adulthood (gender-specific, manhood or womanhood). In common usage in western, English language countries, "adolescent" and "teenager" may be considered synonyms (though it should be noted that the term 'teenager' is an artifact of the English counting system, not something that occurs in most languages), though the exact endpoints of each category don't always coincide depending on the definition of "adolescent" being used. Adolescence is the transitional stage of human development in which a juvenile matures into an adult.
