A teenage girl is typically defined as a female between the ages of 13 and 19. This period is marked by significant physical, emotional, and social changes as she transitions from childhood to adulthood. Teenage girls often experience puberty, which includes growth spurts, the development of secondary sexual characteristics, and hormonal changes that can affect mood and behavior. During these years, teenage girls may engage in various activities such as school, sports, and social events. They often form close friendships and may explore their identities through interests in fashion, music, and social media. This stage is crucial for developing self-esteem and independence, as well as navigating relationships with family and peers.
