teenage
UK: ˈtiːneɪdʒ | US: ˈtiːneɪdʒ
adj. relating to or characteristic of teenagers (ages 13–19)
n. the period of life between childhood and adulthood
The word "teenage" combines "teen," derived from the Old English "tīen" (meaning "ten"), and "age," referring to a period of time. In English, numbers 13 to 19 ("thirteen" to "nineteen") all end with "-teen," historically marking them as "ten plus X." Over time, "teen" became shorthand for this age group, and "teenage" emerged in the early 20th century to describe the transitional phase between childhood and adulthood. The logic is straightforward: the "-teen" years (13–19) define this life stage.
