"Preadult" is a term used to describe someone who is not quite an adult yet, but also not a child. Some synonyms for "preadult" include "adolescent," "preteen," "tween," "teenager," and "youth." These words all describe someone who is in the transition between childhood and adulthood. Each of these words has slightly different connotations, with "adolescent" often being associated with puberty and hormonal changes, and "tween" usually referring to those between ages 10-12. "Teenager" is a more general term, while "youth" connotes a sense of vibrancy and energy. Whichever word you choose to use, it's clear that preadults are a unique and important demographic in today's society.
