Pre-teens are children in the age group of 9-12 years old, also referred to as tweens or preadolescents. Tweens refer to those who are transitioning from being a child to a teenager. Preadolescents signify the period of development between childhood and adolescence. Other synonyms for pre-teens include 'tweenagers' and 'adolescent juniors.' These terms reflect the liminal stage of pre-adolescence where children are not quite kids but aren't quite teenagers yet. During this era, young people experience a gamut of changes that range from physical growth and hormonal development to emotional and social immaturity. Understanding these synonyms helps us communicate better with tweens.
