There are many different synonyms that can be used to describe a young person. Perhaps the most common term is "youth," which applies to anyone in the early stages of life. Other terms that can be used include "adolescent," which refers specifically to individuals in their teenage years, and "teenager," which is even more specific to those between the ages of 13 and 19. "Junior" is another word that can be used to describe young people, particularly when they are in school. Other possibilities include "youngster," "juvenile," and "young adult." Each of these terms has its own specific connotations, and choosing the right one depends on the context of the situation.
