A female is typically referred to as a "girl" up until she is around 18 years old. However, this age is not a strict rule and can vary depending on context and social norms.
In more detail:
- The term "girl" generally applies to females who are younger than women.
- Legally and socially, the age of 18 often marks the transition from childhood to adulthood. Therefore, 17 and under are generally considered girl age.
- However, usage can be flexible. For example, a younger adult woman might be casually referred to as a "girl" among friends. Likewise, the term can sometimes be used informally to describe a woman of any age.
Therefore, while there's no precise cutoff, under 18 years old is the most common and widely accepted age range for being called a "girl."
